Accessible one bedroom ADU
A smart, mid-size two-bedroom detached ADU over a garage that balances comfortable living space with real storage and parking below. The main floor is designed around a bright, open great-room feel—featuring a spacious living room, dedicated dining area, and a full kitchen with pantry—plus two true bedrooms for flexibility.
With a covered porch entry and a layout built for everyday livability, The Summit is a great fit for long-term rental income, multigenerational living, or a private backyard home that doesn’t feel “small.”

What’s Included in the Seattle DADU plan set?
This plan set provides the core drawings needed to define the layout, exterior design, and overall construction intent—so you can move forward with pricing, planning, and permitting.
Typically included:
- Floor plan layout(s) and dimensions
- Exterior elevations
- Core architectural details needed to price and permit the build
Still required for permitting (site-specific):
You’ll still need a site plan, utilities/connection details, and completed permit paperwork based on your jurisdiction’s requirements. We can help identify what’s needed for your lot and coordinate next steps.
