Explore What We’re Providing

Built for Kirkland, Designed Around You

Kirkland homes are diverse—early craftsman builds, infill developments, and remodels that never quite made sense. Our job is to fix what’s not working, expand what is, and deliver construction that actually feels finished.

At Signature Build, we specialize in custom home construction, ADU and DADU builds, garage conversions, and additions across Kirkland, Washington. Our in-house team manages every step—no outsourcing, no handoffs. We’ve delivered second-story additions in Rose Hill, garage ADUs in Highlands, and custom homes in Norkirk—always with precision and a deep understanding of Kirkland code.

If you’re planning a new build, addition, or conversion, we’re here to make sure the end result works the way you need it to.
