Architect in Bothell, WA — Piper Cole Architects

Bothell spans two counties — King and Snohomish — and has grown significantly as housing demand has pushed northward from the Seattle core. With the University of Washington Bothell campus, Canyon Park tech employment, and easy access to SR-522 and I-405, Bothell attracts a diverse residential population and active commercial development. Piper Cole Architects serves Bothell homeowners and businesses with residential and commercial architecture services.

Custom Homes in Bothell

Bothell has a mix of established residential neighborhoods and newer development areas offering custom home opportunities. Sites in the Kenmore-Bothell area near Lake Washington, the North Creek corridor, and the rural edges of the city offer varied terrain and character for custom home design. We design homes that respond to their specific sites — capturing views, managing stormwater through thoughtful grading, and creating homes with genuine design quality in a market where production builders dominate.

Home Additions and Renovations

Bothell’s housing stock includes established mid-century homes in older neighborhoods and newer production homes on the north end of the city. Both present different renovation opportunities — the mid-century homes often have excellent bones but dated floor plans; the newer production homes often need quality upgrades to match homeowner expectations. We design renovations appropriate to each context.

ADU Design in Bothell

Bothell allows ADUs on residential lots following state law. In areas where Bothell’s jurisdiction overlaps with Snohomish County (for properties outside city limits), permit requirements differ. We confirm jurisdiction before design begins on every Bothell project.

Commercial Architecture in Bothell

Bothell’s Canyon Park corridor is a significant suburban employment center with active office and light industrial development. The downtown Bothell revitalization effort has also created opportunities for mixed-use and retail projects. We design commercial tenant improvements and new buildings throughout the Bothell area.

North Creek and Wayne Golf Course Area

The North Creek watershed runs through Bothell, creating critical area buffers that affect development on many residential lots. Properties near North Creek require critical area review and may have building envelope restrictions. We identify these constraints in our feasibility assessment phase before any design work begins.

Bothell Permitting

Bothell building permits are processed through the City of Bothell’s Community Development Department. Properties outside city limits may fall under King County or Snohomish County jurisdiction.
