Backyard in Walla Walla, WA

Walla Walla summers regularly push afternoon highs near 90 degrees while nights fall into the 50s, a dramatic daily swing that shapes how an outdoor space actually gets used here. Designing a backyard in Walla Walla, WA, means planning for both the heat of a July afternoon and the chill of the very same evening, because the most usable outdoor rooms work comfortably across that entire range. A space built only for one extreme sits empty half the time, while one designed for the swing earns its keep from spring through late fall.

The region's semi-arid climate drives every material and layout choice you make. With only about 16 inches of rain a year and intense high-desert sun, surfaces and finishes face heavy UV exposure, while winter freeze-thaw works steadily on any patio or footing set too shallow. A well-planned outdoor living space in Walla Walla answers all of this with shade for the heat, fire for the cool evenings, and hardscape built to survive the cold. Thoughtful design turns a genuinely difficult climate into a long, comfortable, usable season.

For the past 22 years, we at DunRight Construction have transformed backyards across the area to fit each owner's style and the way they actually live outdoors. From outdoor kitchens and fire pits to patios and landscape lighting, our team builds spaces meant to be lived in, not just looked at from a window. If you have a vision for your yard, we would be happy to help you shape it into something real and lasting.

Walla Walla's climate is one of real extremes, and a backyard has to answer all of them. Summer afternoons climb into the upper 80s and 90s under intense high-desert sun, while the same nights can drop 30 to 40 degrees, a wide diurnal swing that is typical of the valley. With roughly 16 inches of annual precipitation, the air stays dry, so unshaded patios bake by day and surrender their warmth quickly after sunset.

That pattern affects materials and comfort alike. Strong UV fades unsealed wood, weathers finishes, and overheats dark hardscape, while winter sends temperatures below freezing repeatedly, driving freeze-thaw cycles that lift patios and crack footings set above the frost line. Summer humidity often sits in the teens, which dries out timber and loosens fasteners faster than a coastal climate ever would. The practical lesson is that a usable outdoor space needs three things: shade or structure to tame the harsh afternoon, a heat source to reclaim the cool evening, and properly bedded, freeze-resistant hardscape underneath it all. Build for the swing rather than a single season, and the yard stays comfortable far longer each year.

A backyard is only as durable as the materials it is built from, and the local climate rewards a few very specific choices. For an outdoor kitchen, the grade of stainless steel matters: 304 stainless resists corrosion far better than the cheaper 430 alloy, an advantage that pays off under intense sun and constant temperature swings. Countertops fare especially well in sealed natural stone like granite, which handles UV and heat without fading, whereas many concrete or tile surfaces eventually craze and discolor.

Fire features deserve the same scrutiny. A wood-burning pit delivers high heat and ambiance but needs clearance and ash management, while a gas-powered design offers instant, controllable warmth measured in BTUs, ideal for taking the edge off a cool valley evening. Underneath it all, any patio or footing should be below the frost line on a compacted base so freeze-thaw movement cannot heave it over time. Even the wood you choose matters here, since cedar and thermally modified lumber shrug off the dry heat better than untreated softwoods. Drainage matters even in a dry climate, since the rare summer cloudburst can pond against a footing fast, so we grade and channel runoff away from every structure we set. Landscape lighting, run on low-voltage systems, then extends the usable hours well into the night.
