Bothell’s unique position spanning two counties means building codes can vary significantly from one street to the next. We are experts in both jurisdictions, managing the specific permitting nuances for projects in Canyon Park, Thrasher’s Corner, or North Creek. From managing North Creek buffer zones to meeting UW Bothell vicinity stormwater requirements, we handle the technical red tape so your addition is fully compliant and built to last.
With Bothell’s 2026 zoning updates, adding an Accessory Dwelling Unit (ADU) has never been more advantageous. We design and build attached and detached suites (up to 1,200 sq. ft.) that serve as premium rental income properties, private guest quarters, or home offices. Our Bothell ADU projects focus on "Small Footprint, Big Luxury," utilizing vaulted ceilings and smart storage solutions to make compact living feel expansive.
In the modern Bothell home, the kitchen is the command center. Our expansion services focus on opening up cramped floor plans to create "Great Rooms" that flow naturally into your dining and living areas. By extending your footprint, we can integrate walk-in pantries, professional-grade appliances, and oversized islands that transform your home into the ultimate space for family gatherings and entertaining.
When your backyard space is a priority, we look upward. Second-story additions are an ideal way to add multiple bedrooms or a primary suite without sacrificing your garden or patio. We specialize in vertical engineering, ensuring your Bothell home’s foundation is reinforced to support the new level. Our designs focus on architectural continuity, so the new story looks like a natural evolution of your home’s original silhouette.
As part of the Cascadia Innovation Corridor, Bothell homeowners need spaces that work as hard as they do. We build "flex" additions designed for the 2026 lifestyle—sound-proofed home cinemas, high-bandwidth home offices, or private gyms. These spaces are pre-wired with the latest smart-home hubs, allowing you to control lighting, climate, and security with a single tap, ensuring your addition is future-proofed for decades.
Washington’s 2026 Energy Codes are some of the strictest in the nation. Our Bothell home additions utilize high-performance building envelopes, triple-pane windows, and high-efficiency heat pumps to exceed these standards. By prioritizing sustainability, we don't just add space; we lower your utility bills and increase your home's resale value, making your addition a responsible investment in both comfort and the environment.
