Custom Deck Design & Construction in Washington

Design a Deck That Reflects How You Live

We Build Custom Outdoor Spaces from the Ground Up

At Alliance Deck Builders of Washington, custom means more than choosing your board color. It means we design from scratch — guided by your yard, your budget, and your goals. Whether you're adding space for family dinners, outdoor parties, or quiet weekend mornings, we build decks that do more than look good. They serve your lifestyle, meet Washington code, and stand strong in all seasons.

Every Deck Starts With a Smart Plan

Here’s What Goes Into a Great Custom Build

From the first sketch to final screws, our custom deck process includes detailed 3D planning, material matching, and structural engineering. We factor in sun angles, drainage patterns, slope, access, and future add-ons — not just the shape of your yard. We take time up front to make sure your design works beautifully and lasts for decades.

Our Custom Deck Design Process

How We Take You from Sketch to Finished Deck

Our deck design process starts at your home. We listen to your goals, evaluate the build site, and suggest ideas based on how you want to use the space. Then we create digital drafts — often with multiple layout options — to help you visualize your future deck. Once approved, we move into construction using the same team that designed your project, ensuring nothing gets lost in translation.

Details That Make a Difference

Design Features That Add Value and Use

Want built-in seating? Wraparound stairs? A grilling station or privacy screens? We don’t just build “a deck.” We integrate smart features that turn your deck into an outdoor room. From accent lighting and under-deck storage to unique shapes and material inlays, we tailor every build to how you want to live.

Built for Washington's Terrain and Climate

Smart Foundations and Framing from the Start

From coastal cities to hillside properties, Washington offers beauty — and construction challenges. We assess grade, soil, access, and exposure before digging. Our decks are built with deep-set footings, corrosion-resistant fasteners, and pressure-treated framing lumber. Whether you need ground-level support or elevated platforms, we ensure your deck stands level, drains properly, and complies with code.
