Introduction A well-apPointed patio is the perfect example of enhanced outdoor living space. Designed around your lifestyle and favorite leisure activities, a patio can be comfortable, spacious, and even versatile, just like any well- used indoor gathering place. But what makes a patio so special are the things you can’t get under your roof: pure sunlight, open air, an atmosphere that changes hourly and with the seasons- in short, a direct connection to the outdoors. It is this unique combination of comfort and the natural world that gives patios the power to lure us out of the house and away from our indoor routines. As an “outdoor room,” designing and decorating a new patio is not so different from planning any other living space. The design rule “function comes first” certainly applies. Assessing how everyone in the household will use the new patio is the primary consideration that influences every other decision, from planning the size, shape, and layout to choosing paving materials and adding special features and amenities. One of the great things about building a new patio or walkway is the number of options you have to choose from. Few other building projects offer so many choices of materials, configurations, and even locations-unlike a deck or balcony, a patio doesn’t have to be tied to the house or confined to the back yard; it can welcome guests at the front door or host an intimate gathering around a fire pit in a far corner of your lot. With all of this flexibility, a patio can complement your home’s architecture as much as it shapes your landscape, and that’s what makes creating a patio from scratch such a rewarding project. If a patio is a stage from which you can enjoy the outdoors, walkways and paths are the ties that bring it all together, linking the house, patio, garden, lawn, driveway, and any other points in between. Pathways unify various landscape elements in both functional and perceptual ways: they define spaces, direct traffic, and make it easy to travel from one place to the next. They also draw a line between separate, sometimes distant, spaces- joining them visually and inviting us to venture on to the next destination. Thinking about patios and walkways together is a smart choice, as both can transform an outdoor home. It’s not surprising, then, that a new patio project often leads to new walkways as well. Whether you’re dreaming of a new patio, a new walkway, or both, this book will take you through the process from start to finish- from gathering ideas and choosing materials to preparing the site and laying the surface. After surfacing, you can set out some furniture and enjoy the fruits of your labor or you can gather more tools and start right in on another project, such as installing landscape lights or building an outdoor kitchen. Either way, as soon as you begin to enjoy your new patio, you’ll quickly understand why so many do-it-yourselfers see their patios as works in progress- it’s fun to keep thinking up new and creative ways to make your favorite outdoor spaces even better.
• 5Patio & Walkway Basics T o install a new patio or walkway, first get started by working through the basic steps of planning your project. The section in this chapter on design themes can help you think conceptually about the character and emotional quality of your new outdoor room. Consider, also, all of the ways you hope to use the new space and decide how the layout and other design elements will best accommodate those activities. Next comes the choice of paving material. Whether it’s classic clay brick, naturally rough-hewn flagstone, simple and sleek concrete, or any of the other great options you’ll learn about here, the surface material you choose will be the defining feature of your patio or path. In addition to the appearance and performance qualities of the different paving options, make sure to think about the logistics of installation. Flip ahead to the step-by-step projects in this book and review the materials to get an idea of the work involved and to gauge which applications best suit your design, budget, and time frame. Other practical matters to consider- including zoning restrictions and natural conditions on your property, such as drainage and seasonal weather- are addressed in this chapter as well. \t\Then it’s time to pull it all together, you’ll find it helpful to draft a site plan. The patio and walkway plans on pages 33 to 37 offer inspiration and tips for thinking globally about your patio or walkway in the context of your outdoor home.

Privacy can take many forms and often is as be somewhat limited functionally. If this is not what much a result of perception as physical seclusion. you want for your entire patio, you can always make Adding privacy might mean screening out the views of some parts private while leaving others open. Another neighbors or locating the patio in a distant corner of option is to build a small private retreat away from the lot. A fountain or other water feature can provide the main patio. Whatever the design, a private patio a sense of privacy by drowning out noise and letting should be personal and comfortable, particularly for you dwell in your own thoughts. Along with increased those who will spend the most time there.
Urban patios often rely on tall fences or walls for much needed privacy. Plantings help soften the look of the barriers and prevent a closed-in feeling.

This sprawling outdoor room maintains an expansive feel with a visual flow between levels. Accents of boulders and trees that echo the view of distant mountains blend this patio into the natural openness of the land.
The most important idea behind expansive patios borrow views of the natural landscape and create the is openness.

However, creating an can help frame the view from the patio, but a large over- expansive feel is not about maximizing the patio’s head might be too oppressive and can detract from the size. In fact, small patios can gain the most from an open feeling. An expansive theme works well for remote expansive theme- leaving patios open allows them to outdoor rooms as well as patios right next to the house.

A freestanding into the landscape or become an eye-catching or detached patio can be remote both literally and focal point on its own. Detached patios are often psychologically. A remote space can be private, created to supplement a patio or deck adjoining the tucked behind dense foliage at the end of a path, or house.

A remote patio is ideal for a private retreat. Being away from the house, it can take on a unique architecture to elicit a particular mood. Here, a classical romantic setting allows the homeowners to feel as though they are far away when they are just in the back corner of the yard.

Patio (7 Walkway Basics • 17I stone Natural stone has an organic beauty that’s unmatched by all other building materials. Stone paving is used all over the world in grand courtyards, ancient road- ways, and back yard landscapes alike. In nature, stones frequently form paths for crossing streams and skirting muddy fields- it’s not surprising, then, that it’s a popular material for patios and walkways. Stone is available in many forms, while the most commonly used types for do-it-yourself projects are flagstone and stone tile.
I Flagstone Flagstone is the general term given to any broad, flat stone that has been split to a thickness of around one to four inches, making it good for paving. Common species of flagstone include sandstone, limestone, bluestone, and slate . Individual stones may have cut edges for paving in linear patterns, while stones with jagged edges and irregular shapes are best for creating a patio or walkway surface with a natural, casual feel. Flagstones can be set in sand or stable (tamped) soil, or they can be permanently laid in mortar over a concrete patio slab or walkway. For an organic, stepping-stone effect, you can space stones widely and fill the gaps with gravel or groundcover plantings. Availability of flagstone varies by region; see what types are offered at local stone yards. For paving on patios and primary walkways, make sure the stone is thick enough for furniture and/or heavy foot traffic and that the surface of the stones won’t become dangerously slick when wet.

Buying Stone ~
Flagstone is typically sold by the square yard or by
the ton. Before you start shopping, calculate the area
of your patio in square feet. Stone suppliers can use
this number to estimate your requirements in tons,
if necessary. Buying flagstone in bulk from a stone
yard is less expensive than hand-selecting individual
stones, though you don't get to inspect all of the
pieces in advance. Also, purchasing bulk shipments
preloaded onto pallets helps prevent breakage before
and during delivery. To estimate quantities of stone
tile, calculate the total area you need to cover, then
factor in the thickness of the grout joints. Your tile
supplier can help with these calculations.
Here are some other things to think about when
considering stone for your patio or walkway:
• In general, the difficulty of quarrying and
dressing stone makes it a relatively expensive
material. The more work that's done to the
raw material-hand-selection, cutting, and
finishing-the higher the cost.
• When it comes to a finished patio, one of the
main drawbacks of some flagstone is its uneven
surface, which can lead to wobbly tables and
the occasional stubbed toe. However, many
people choose stone specifically for its natural
"imperfections."
• Softer flagstone, such as sandstone, can split

I Decorative Effects for Poured concrete While many people like the clean, monolithic look of a plain concrete slab, there are several options for adding decorative touches to a new concrete surface: Seeded concrete is finished with a layer of fine stones for a uniform, yet organic, effect . This is a popular choice for patios because of its multicolored, textured appearance and nonslip surface. A divided concrete slab is poured with permanent wood dividers and border edging, separating the slab into equal sections. In addition to its decorative value, a divided slab is also easier to work with, since it allows you to pour and finish one section at a time, if desired. Tinting and acid staining introduce a range of color options to the familiar cement gray of plain concrete. Commercial colorants, available in both liquid and powdered forms, can be added to wet concrete mix for consistent color throughout the material. This is a good option for mold-formed walkways and other projects that call for small batches of wet concrete. For larger projects, you can order ready-mix concrete in a limited range of colors. Acid One of the best things about poured concrete is its staining is a simple, permanent treatment for cured malleability: in its liquid form, concrete follows curves and concrete slabs and can be applied at any time after angles just as well as straight lines, making it a great medium the concrete has fully cured. for custom shapes and sizes.

They also tend to be much less expensive than most other paving options and couldn’t be easier to install. In a typical installation, start with a bed of compacted gravel and cover it with landscape fabric to inhibit weed growth and separate the gravel base from the surface material. Then, spread out the surface material a few inches thick, compact it if necessary, and you’re done! For simpler applications, such as a lightly traveled garden path, you can often skip the gravel base and lay the landscape fabric right over leveled and tamped soil. In most cases, it’s best to include a raised edging of some kind to contain the materials and maintain the shape of the paved surface.
I Selecting Loose Materials
Because different loose materials can have very
different textures and properties, it's important to
choose the right surface for the application. Here's a
look at some of the most popular materials for patios
and walkways:
Decomposed granite: A popular choice for
level patios, paths, and driveways, decomposed granite
(DC) can be compacted to a relatively smooth, flat,
hard surface. DC consists of small pieces of granite
ranging in size from sand-size grains to a quarter
inch-this size variation is the reason this material
is so compactable. DC is available in various natural
shades of gray, brown, and tan. Due to its gritty, sandy
finish that can stick to your shoes, DC is not a good
choice for surfaces that receive heavy traffic directly to

gravel are compactable, but usually less so than DG. Gravel made up of round stones is more comfortable to walk on than jagged materials. River rock: Smoothed and rounded by water or machines, river rock ranges from small stones to baseball-sized (and larger) rocks. These smooth surfaces make it more comfortable to walk on than jagged gravel but it is also less compactable and easily displaced underfoot. Larger stones are difficult to walk on and are more suitable for infill and accent areas than for primary paving surfaces. Pea gravel Wood chips: Wood chips and mulch are commonly used as groundcover in planting beds, gardens, and flowerbeds. Most types are soft and springy underfoot, and many can be used for light- traffic paths and even children’s play areas. Wood chips come in a wide variety of grades, colors, and textures. In general, finely chopped and consistent materials are more expensive and more formal in appearance than coarse blends. The term mulch is often used interchangeably with wood chips but can also describe roughly chopped wood and other organic matter that’s best suited for beds and ground cover. Most loose material made of wood needs some Crushed stone replenishing every two to four years. Both stone and wood loose materials are typically sold in bulk at landscape and garden centers and by the bag at home centers. Buying in bulk is often much less expensive for all but the smallest jobs. Landscape and garden suppliers typically offer bulk deliveries for a reasonable flat fee. Due to the variance in terminology and appearance of loose materials, be sure to visit the supplier and take a look at the materials you’re buying firsthand, so you know exactly what to expect.

Permeable patio and walkway surfaces include sandset pavers and stone, as well as all loose materials, while poured concrete and mortared surfaces are essentially impermeable. From a green standpoint, impermeable surfaces are fine as long as your patio or walkway is sloped toward an area of natural ground that is large enough to capture and absorb all (or most) seasonal runoff. However, if you have a large paved surface that drains onto another impermeable surface, such as a driveway or street, consider using a permeable paving material instead of solid concrete, or plan for an adequate buffer zone of natural ground between the new surface and other paved areas.

Patio (7 Walkway Basics • 25IPractical Considerations
I n addition to the creative work of planning the look and feel of a patio space, there are several practical matters that must be addressed before you can hit Visualizing Your Patio ~ Create a quick mock-up to help you plan your the drawing board. Thinking about how you will use patio’s size, shape, and location. Mark the proposed the patio will help you answer one of the biggest space with rope or garden hose, and set out any questions-how much space you’ll need. The planning furniture you’ll use. See how it all looks from different stage is also the time to consider environmental points on your lot, as well as from inside the house. factors, including site drainage, sunlight, and wind, to make sure your patio will be both comfortable and usable whenever you’re ready to get outside. Finally, it’s a good idea (and possibly required by law) to check with your city’s building department to learn about building code requirements and zoning restrictions that might affect your project plans.
I Use How you plan to spend time on your patio will influence many of your design decisions, so it’s best to start the planning process by brainstorming with everyone in your household. What will be the primary uses for the space? Dining, entertaining, sunbathing, playing with the kids, enjoying the view? Once you establish the uses, see if you can accommodate all of those activities within an attractive, efficient design. For some, the solution lies simply in providing adequate space in a flexible floor plan-a quick shift in furniture, for example, can set the stage for the next activity. In thinking about everything you hope to do on your new patio, imagine the ideal setup for each activity. For example, if you have young children, maybe you want a comfortable sitting area near an edge of the patio that’s adjacent to a sandbox (or even a sandbox built into the patio; when the youngest has outgrown it, you can turn it into a planting bed). Or maybe you want some space on the patio for a baby If your plan is to refurbish an existing patio, pool or a fountain for the kids to play in. think hard about what you like and dislike about A patio that’s good for entertaining, as well as the current setup.

This includes detailed steps for setting up reference lines and creating a stable foundation for any type of patio surface. If you’re still weighing your options with different patio materials, consider ease of installation: the fastest and easiest patios to build are those made with loose materials. Next are sandset surfaces that require careful planning and layout, but it’s relatively easy to correct mistakes. With m ortared surfaces, you’re working against the clock to get everything set and cleaned up before the mortar hardens, and mistakes are tough to fix. Poured concrete is the most challenging material, due to the time sensitivity and the finer points of finishing.

Repeat filling and spraying until the joints are full and the stones are securely locked in place.
Choosing Soil & Plants for Your Patio ~
Sand-based soil (also called "patio planting" soil)
is the best material to use for planting between
flagstones. This mixture of soil and sand sweeps
easily into joints, and it resists tight compaction to
promote healthy plant growth, as well as surface
drainage. Regular soil can become too compacted
for effective planting and drainage and soil from
your yard will undoubtedly contain weeds. Sand-
based soil is available in bulk or by the bag and is
often custom-mixed at most large garden centers.
As for the best plants to use, listed below
are a few species that tend to do well in a patio
application. Ask a local supplier what works best
for your climate.
• Alyssum • Saxifrage
• Rock cress • Sedum
• Thrift • Thymus
• Miniature dianthus • Scotch moss
Patio "planting soil" (for planting between stones) is available
• candytuft • Irish moss
in bulk or bags at most garden centers. It is good for filling
• Lobelia • Woolly thyme cracks because the sand base makes it dry and smooth enough
• Forget-me-not • Mock strawberry to sweep into cracks, yet the black compost will support plant
growth. Because it is bagged, you can be assured it doesn't come
with weeds.

I How to Build a Round Concrete Patio
Establish layout lines for the site excavation using batterboards, mason’s string, and inverted marking paint. Set the lines so they reach at least 12” beyond the work area on all sides. Plan for the gravel base to extend 12” beyond the slab. Use two pairs of perpendicular batterboards with strings to establish the centerpoint of a round patio (where the strings intersect). To create a rough outline for the patio excavation, drive a stake at the centerpoint and then attach a string to the top of the stake. Tape the other end of the string to a can of inverted marking paint so the distance from the stake to the can equals the radius of the circle, including the gravel base; mark the outline.

A cid staining is a permanent color treatment for cured concrete that yields a translucent, attractively mottled finish ideally suited to patios. Unlike paint or Another important preparation step with either new or old concrete is to color-test a few shades of stain on the concrete you’ll be working with. Stain pigmented concrete stains, both of which are surface suppliers often sell sample-size quantities of stain for coatings, acid stain is a chemical solution that soaks into this purpose. Since acid stain affects every surface the concrete pores and reacts with the minerals to create a little differently, it’s worth the effort to run a test the desired color.

Working with Concrete ~
Estimating concrete can be done with a simple
calculation. Concrete quantity is measured in cubic yards.
To calculate the volume of concrete needed for your
project, simply follow these steps:
1. Multiply the width and length of the slab (in feet)
to find the total square footage. For example: 10ft.
(width) x 12 ft. (length) = 120 sq. ft.
2. Convert the thickness dimension of the slab
to feet by dividing by 12. For example: 4" (slab
thickness) + 12 = 0.33 feet.
3. Multiply the square footage by the thickness to
find the cubic volume in feet, then divide by 27 to
find the cubic yard volume: 120 x 0.33 = 39.6 cu. ft.
39.6 + 27 = 1.47 cu. yd.
When estimating concrete needs, it's best to round up to
the nearest half increment to make sure you don't run
short. Therefore, for a slab volume of 1.25 cubic yards,
purchase or order at least 1.5 yards of concrete.
Isolation joints prevent the wet concrete from
bonding to the adjoining structure and act as a cushion
to prevent damage if any seasonal movement occurs. Isolation joints are required wherever a new concrete slab
The standard material for slab isolation joints is W'-thick abuts a permanent structure, such as a house foundation, a
wall, or another concrete slab.
asphalt-impregnated fiberboard. The board should be
glued or nailed to the adjoining structure prior to the
concrete pour. After the new concrete has cured, trim off
the top 1/2" or so of the isolation board and fill the joint
with a suitable masonry caulk, if desired.
A control joint works somewhat like a fault line:
because cracking is a normal occurrence with slabs, the
joint creates a weak spot in the structure, encouraging
cracks to follow the joint (where they are less visible).
Consult your local building department for
recommendations and requirements for control joint
frequency and placement. In general, a control joint
groove should equal a quarter of the total slab thickness
(for example, a 4"-thick slab gets 1"-deep joints). For best
performance and appearance, arrange control joints in
a symmetrical grid pattern, dividing the slab into roughly
equal square sections. For large slabs, control joints are
typically required every 8 to 12 feet. Joints in concrete
walkways are typically spaced at one-and-a-half times the
width of the walkway sections (for example, a 2-foot-wide
walkway should have a control joint every 3 feet).
Control joints are permanent, straight grooves cut into the
top surface of concrete slabs during the finishing process.98 • COMPLETE GUlDE TO PATIOS & WALKWAYS
When mixing your own concrete, work withpremixed dry concrete. It is commonly sold in 60- and 80-lb. bags. Using premixed concrete ensures you get the right formulation for quality results. There are several types of premixed concrete, each with specific properties-such as fiber-reinforced or high-early- strength-so choose the formulation that best suits your application. A 60-lb. bag of concrete mix yields roughly half a cubic foot of solid concrete. For a patio slab, the number of bags required adds up quickly.

Patio Projects • 137Walkways & Steps A walkwa y or path can do much more than provide a route for foot traffic. A path can be a versatile design element, creating an attractive border along a house, a patio, or landscape features. It can also become an attractive transition between two areas, such as a lawn and a planting bed. Walkways and paths are also effective at unifying spaces in the landscape. For example, imagine a back yard with a patio at one end, a beautiful flower garden at the other, and a solid swath of lawn in-between. By adding a footpath, you connect all of the areas. In terms of construction techniques and material, a walkway is essentially a patio in a different configuration. All of the same materials that make great patio surfaces are equally as suitable for walkways. In this chapter, you’ll find complete projects utilizing all major walkway materials, plus some you might not have thought of. As in the chapter on patio projects, there’s also a special section with tips for planning your walkway project and laying out the site (see pages 140 to 143).

D esigning and planning a new walkway starts with
a careful assessment of how the path will be
used. Landscape designers commonly group outdoor
walkways into three main categories, according to use
and overall design goals.
The first is a primary walkway: a high-traffic path
used by household members and visitors, such as a
walkway between the street and the home's main entry
door. A main path should provide the quickest and
easiest route from point A to point B. Any unnecessary
twists and turns are likely to be cross-cut by walkers,
leaving you with a less manicured path through the
yard. To allow two people to walk side-by-side, a main As an important part of a home's curb appeal, a primary

you live in a snowy climate), such as poured concrete,
pavers, or flat stones.
A secondary walkway typically connects the house
to a patio or outbuilding or a patio to a well-used area
in the yard. A comfortable width for single-person
travel is 24 to 36 inches. Surfaces should be flat and
level underfoot and provide good drainage and slip-
resistance in all seasons.
The third type, a tertiary path, is informal,
perhaps nothing more than a line of stepping stones
meandering through a flower garden or a simple
gravel path leading to a secluded seating area.
Design tertiary paths for a comfortable stride, with a
minimum width of 12 to 16 inches.

decoration. A gentle curve here and there adds interest

Variation: As an alternative to paving over an entire walkway (if the old concrete still looks good), add a decorative touch with a border of mortared pavers along the edges.

To install edging along a walkway, follow the basic techniques shown in steps 1 to 4 on page 161, but set the pavers flush with the walkway surface. Position the pavers horizontally or vertically, depending on the height of the walkway and the desired effect. After the pavers are set and tooled, follow step 10 above to complete the job.

Walkways (7 Steps • 191I Boardwalk W hether as a garden path or a high-traffic walkway, a boardwalk can add a touch of elegance to any yard. The simplicity of this project’s design makes it an easy solution to many walkway problems. Frames measuring 29 x 45” are constructed from pressure-treated lumber and recessed in trenches along the project area. Cedar decking boards conceal the frame, creating a lovely walkway surface through your yard. The boardwalk should be built on a relatively flat stretch of ground. For greater stability, fasten the frames together with Yl6 x 2 Y2” galvanized lag screws driven through both sides of the end boards.

Walkways (7 Steps • 193Patio Rooms & Amenities F eaturing several projects for turning an ordinary open patio into a custom outdoor room, this chapter is all about making the most of your patio space. A patio room is more of a design concept than a specific type of structure. The idea is to enhance a space with just the right elements to make it more usable, comfortable, or private. If your patio feels just a little too exposed or if the layout could use some definition and a sense of enclosure, an overhead or side screening could be just what’s needed to complete your outdoor oasis. If you like the protection of a covered patio but don’t want a solid roof overhead, then a patio enclosure may be the perfect alternative. Or, for a truly classic patio overhead, you can’t beat the look and subtle shading of a cedar arbor. You’ll even find a project for transforming the undesirable space under a second- story deck into a pleasant covered patio. As for amenities, we’ve included two of the most popular back yard projects: an outdoor kitchen for the patio and landscape lighting, that can be used on a patio or walkway. If you’re building a new patio and want to include either of these amenities, be sure to plan for the utility hookups early in the process, in case you need to run lines under the patio surface.

The line will correspond to the top edge of the gutter channel. The ideal slope is V,6” per foot. For example, with a 16-ft.-long gutter, the beginning is 1” higher than the end. The downspout should be located just inside the low end of the gutter channel. Mark the beam at both ends to create the desired slope, then snap a chalk line between the marks.

Patio Rooms (7 Amenities • 205IPatio Enclosure
I f you like the openness and plentiful light of a patio
but want more protection from rain and strong
winds, this stylish, contemporary patio shelter may
be just what you're looking for. Designed as a cross
between an open-air arbor or pergola and an enclosed
three-season porch, this patio structure has clear
glazing panels on its roof and sides, allowing plenty
of sunlight through while buffering the elements and
even blocking harmful UV rays.
The roof of the patio shelter is framed with closely
spaced 2 x 4 rafters to create the same light-filtering
effects of a slatted arbor roof. The rafters are supported
by a doubled-up 2 x 10 beam and 4 x 6 timber posts.
Because the shelter is attached to the house, the posts
are set on top of concrete foundation piers, or footings,
that extend below the frost line. This prevents any
shifting of the structure in areas where the ground
freezes in winter.
The patio shelter's side panels cut down on wind
while providing a degree of privacy screening. Their
simple construction means you can easily alter the
dimensions or locations of the panels to suit your own
plans. In the project shown, each side has two glazing
panels with a 3Yz" space in between, for airflow. If desired,
you can use a single sheet of glazing across the entire side
section. The glazing is held in place with wood strips and
screws so they can be removed for seasonal cleaning.

If you want to build a sealer or protectant. larger arbor, add additional posts between the corner posts. Before you begin construction, check your local building code for footing depth requirements and setback restrictions. The basics of building a freestanding arbor are as follows. First, layout the location of the posts using stakes and string. Make sure the layout is square by measuring from corner to corner and adjusting the layout until these diagonal measurements are equal. Dig postholes at the corners to the required depth using a posthole digger and fill each hole with 6” of gravel. Next. position the posts in the holes. To brace them in a plumb position, tack support boards to the posts on adjoining faces. Adjust the posts as necessary until they’re plumb. Drive a stake into the ground, flush against the base of each 2 x 4. Drive deck screws through the stakes, into the 2 x 4s. Mix one bag of dry concrete to anchor each post. Immediately check to make sure the posts are plumb, and adjust as necessary until the concrete begins to harden. Let the concrete cure for at least 24 hours. Measure, mark, and cut all the lumber for the arbor. Cut a 3 x 3” notch off the bottom corner of each tie beam, a 2 x 2” notch off the bottom corner of each 2 x 4 rafter, and a 1 x 1” notch off the bottom corner of each cross strip. Position a tie beam against the outside edge of a pair of posts, 7 ft. above the ground. Position the beam to extend about 1 ft. past the post on each side. Level the beam, then clamp it into place with wood screw clamps. Drill pilot holes and attach the tie beam to the posts with 3” lag screws. Use a line level to mark the opposite pair of posts at the same height as the installed tie beam. Attach the remaining tie beam. Cut off the posts so they’re level with the tops of the tie beams. Next, attach the rafters to the tops of the tie This version of a freestanding post-and-slat arbor is beams using rafter ties and galvanized nails.

Cladding Posts ~ With their textures and grain, plain wood posts are right at home in many parts of many homes. But when you combine them with gleaming new white vinyl-based products, they can look a little rough. One way to make your patio-roof posts blend better when you’re installing under-deck or screening systems is to clad them and paint them to match. Traditionally, clear dimensional lumber is used for the cladding. But to get seamless results, this often means you need to cut complicated dado-rabbet joints that run all the way from top to bottom at each corner. Then, you need to sand thoroughly and apply several coats of paint. An easier option for making all of your screen system parts match is to clad posts with one-piece PVC -, post cladding (see Resources, page 250). The product shown here is designed to fit around a 6 x 6” post. On the interior surface it is kerfed but the exterior vinyl surface is solid. This way, it can be bent around corners crisply and seamlessly.
Vinyl cladding can be wrapped around wood posts seamlessly.

T hanks to the many inexpensive and easy-to-install
lighting kits and fixtures available, outdoor lighting
has become a standard feature in today's home
spaces a second life with a completely different feel
from the daytime setting.
Standard low-voltage lighting systems are
landscapes. A good lighting plan not only makes your commonly available in complete kits that include a
patio and walkways more useful at night, it gives these low-voltage transformer, low-voltage cable, and several
light fixtures, each with a wire lead that links to the
main cable with a special connector. A basic landscape
kit typically has three or more fixtures for standard
in-ground installation. If you'd like to add specialty
patio fixtures, such as step (or "brick") lights, pole-
and wall-mount fixtures, and task lights for outdoor
cooking, make sure your system is compatible with a
full range of accessory lights. In addition to standard
wired systems, you can find a wide variety of solar-
powered fixtures that offer free operation and the
easiest possible installation.
Here are some other factors to consider when
choosing a standard low-voltage lighting system:
• Transformer power-For best performance, the
total wattage of the light fixtures should be at least
one-third of the transformer's wattage rating but
should not exceed the wattage rating. If necessary,
use two systems to avoid overloading a single
system with too many fixtures.
• Transformer controls-Consider timers and
photosensitive switches for automatic operation.
• Cable gauge size-12-amp UF cable is
recommended to reduce voltage drop, resulting
in dimmer lights at the far end of the line. Long
cable runs may require 8- or 10-gauge wire to
prevent voltage drop.
• Fixture and bulb brightness-Brightness
is often rated in foot-candles: one foot-candle
is equivalent to the brightness of a 12" square
area lighted by a candle held 12" away. Use the
brightness rating to guide the fixture layout.

Choosing Solar Landscape Lights ~
Outdoor solar-powered lighting offers two distinct
advantages over conventional low-voltage systems: easy,
flexible installation and free power. Installing most landscape
and patio light fixtures is as simple as staking the light into
the ground or mounting it to a wall or post. Many fixtures,
including path and accent lights, have a built-in solar panel,
so the fixture can go anywhere it will be exposed to direct
sunlight during the day. Brighter fixtures, like spot and
security lights, often include a separate solar panel with
a thin wire that delivers power to the light. The panel is
mounted and positioned for maximum sun exposure, while
the light fixture can be placed directly where it's needed.
Most solar fixtures come with a photosensitive switch that
automatically turns the light on at dusk and off at sunrise.
The main disadvantage of solar lighting is reliability.
Lower quality fixtures and some high-power lights (such
as spot lights) offer running times that won't last through
Solar landscape lights are available in sets and
the night. To minimize this problem, choose high-quality
individual fixtures. You can pick and choose fixtures based
fixtures with advanced solar cells (better cells collect on lighting needs as well as the fixtures' appearance and
more power in low-light weather than cheaper cells) and brightness. Best of all, you can easily reposition lights for
efficient LED bulbs. desired effects throughout the seasons.
