- Detached backyard cottages and granny flats
- Garage conversion ADUs
- Above-garage living units

Each project is approached as a custom solution rather than a standardized build, with attention given to both functionality and architectural fit.
Experience & Leadership
Founder Jed Stamen transitioned into full-time ADU construction after decades of experience working on large contemporary remodeling projects. His construction background helps guide projects with a focus on practical execution, efficient planning, and long-term build quality.
