ADU Construction in Renton & Greater Seattle
Add Independent Space. Keep the Property Connected.
Accessory dwelling unit projects planned around property access, privacy, compact living, exterior architecture and the relationship between the primary home and the new residential space.
More Than a Small House
Create Independent Living Without Disconnecting the Property.
An ADU should function as a complete residence while maintaining a thoughtful relationship with the primary home, yard, access and surrounding architecture.
We consider how residents enter the space, where windows face, how living and sleeping zones connect, how storage is incorporated and how the exterior relates to the existing property.
The project direction can then coordinate site work, supporting construction, framing, enclosure, interior build-out and visible finishes through one organized sequence.
Property-Wide ADU Planning
Plan the Unit and the Space Around It.
An ADU affects more than its own footprint. It changes access, yard relationships, privacy, views and the way the entire property is used.
The project direction should consider the primary home, property circulation, outdoor areas and the new residence as one connected environment.
