Why Choose a Home Addition in Bothell

For many Bothell homeowners, moving isn’t the ideal solution. Rising property values, limited available lots, and strong community ties make expanding your current home the smarter choice. With a well-planned addition, you can stay in the neighborhood you love, keep your children in the same schools, and enjoy the convenience of familiar surroundings.

Bothell’s unique mix of established homes, newer subdivisions, and semi-rural properties creates endless possibilities for additions. From adding a second floor in a compact neighborhood lot to building a spacious detached accessory dwelling unit (ADU) on a larger parcel, Armada Design & Build has the experience to tailor each project to its setting.
