Home Additions Construction in Seattle, WA

Seattle is a city full of character, from historic craftsman bungalows to modern contemporary homes overlooking Puget Sound. But even in a vibrant city like ours, homeowners often find that their living space doesn’t quite meet their needs. At Armada Design & Build, we specialize in home additions construction in Seattle, WA, designing and building custom expansions that blend seamlessly with your home while giving you the extra space you’ve been dreaming of. Whether you want a second story, an expanded kitchen, a new home office, or a guest suite, our team delivers high-quality additions tailored to your lifestyle and the unique character of your Seattle neighborhood.

Why Choose a Home Addition in Seattle?

Seattle homeowners often face two challenges: limited space and rising property values. Many residents love their neighborhoods—whether it’s Ballard, Capitol Hill, Green Lake, or West Seattle—and don’t want to move. But with growing families or changing lifestyles, space quickly becomes an issue. A well-planned home addition offers the perfect solution: more room without the stress of relocating.

Some of the top reasons homeowners in Seattle choose to invest in an addition include:

• Maximizing existing property in a dense urban environment.

• Adding value in a competitive real estate market.

• Modernizing older homes while preserving their historic charm.

• Creating functional space for work-from-home needs or multi-generational living.

• Enhancing lifestyle with more room for entertaining, hobbies, or relaxation.

With Armada Design & Build, your addition is carefully designed to complement your home’s original architecture and feel like a natural extension of the space you already love.

Types of Additions We Build in Seattle

Seattle’s variety of home styles—from classic craftsman to mid-century modern—means no two additions are alike. Our team customizes every project to suit your house, your neighborhood, and your lifestyle.

We build:

• Second-story additions for maximizing square footage on smaller city lots.

• Room additions such as bedrooms, bathrooms, or offices.

• Kitchen expansions that create open-concept spaces perfect for entertaining.
