The scope, plainly.
An ADU is a complete second residence on a single-family lot, with its own kitchen, bathroom, and entrance. We build attached ADUs (converted basements, garage conversions, and additions) that increase the usable square footage of your property and open new possibilities: rental income, multigenerational living, a home office that finally has a door, or a quiet place for a grown child to land. Washington's 2024 ADU reform (HB 1337) loosened parking, owner-occupancy, and size restrictions across most cities — making now an unusually good moment to build. We handle design coordination, permitting through your local jurisdiction, structural work, MEP, finishes, and final inspection.

Four phases, one crew.
- № 01
Feasibility
Site walk, zoning review, and a candid conversation about what your lot can support and what it will cost.
- № 02
Design
We coordinate with your architect or one of ours — finalizing layout, finishes, and the structural plan.
- № 03
Permit
We submit and shepherd the permit through your jurisdiction, handling corrections and reviewer follow-ups.
- № 04
Build
A single crew, a single point of contact, and weekly progress updates from foundation to final walkthrough.
Other work we do.
Detached Accessory Dwelling Units
Separate, freestanding homes in your backyard — full privacy, full systems, and as small or generous as your lot allows.
New Construction
Custom single-family homes built on infill lots and rural parcels across the greater Seattle area.
Additions & Add-Ons
Pop-tops, room additions, bump-outs, and second-story additions that match the home you already have.
