Seward Park is one of Seattle’s most naturally beautiful neighborhoods, wrapped around Lake Washington with old-growth trees, waterfront streets, and properties that genuinely reward outdoor investment. Alki Deck Builders has worked across Seattle for over ten years, and Seward Park is a neighborhood we build in regularly. Our deck builder team understands the lakeside setting, local permit requirements, and what the Pacific Northwest climate demands from every build. We take the time to get it right from the start.
At Alki Deck Builders, we provide comprehensive outdoor solutions tailored to your lifestyle, property, and budget. Our full-service approach covers design, material selection, permit acquisition, and expert installation to transform your outdoor space.

Seward Park sits on a peninsula jutting into Lake Washington, surrounded by water on three sides and old-growth forest at its heart. That natural setting gives property owners a compelling backdrop and every reason to develop outdoor spaces that take full advantage of it.

Seward Park has the kind of neighborhood feel where people know each other and invest in their properties with care. The community is close-knit and deliberate, and improvements made here tend to reflect that same thoughtfulness.

With lake access, forest trails, and mild microclimate conditions, Seward Park residents treat outdoor living as part of everyday life rather than a seasonal luxury. A well-built deck becomes a genuine extension of the home that gets used constantly.

Many properties in Seward Park have been in families for years, and improvements are made with that kind of long-term perspective. Quality builds using durable materials fit naturally into a neighborhood where people plan to stay.

Seward Park is home to one of the last remaining stands of old-growth forest within Seattle city limits, preserving trees that are hundreds of years old and giving residents a rare chance to walk through ancient woodland just minutes from their front door.
Stylish garden structures that offer gentle shade while enhancing the elegance and visual appeal of your patio or yard.
Covered spaces created for comfortable outdoor living while providing protection for your vehicles from sun, rain, and weather.
Three hundred-plus completed projects, ten years in business, and a 5-star Google rating built through consistent work rather than promises.
