Building Spaces That Grow With You
We design and build thoughtfully crafted ADUs that bring family, function, and sustainable living together in one thoughtful space.
At Green Built Cottages, we believe an ADU is more than just extra square footage, it’s a place where family can stay close, creativity can flourish, and life can expand in new directions. From cozy backyard cottages to reimagined garages and basements, we design and build thoughtfully crafted and sustainable spaces that feel personal, purposeful, and truly yours.
WHY US
Spaces We Craft
For over three decades, GreenBuiltCottages/Bogman Co. has designed and built homes & ADUs across CA & WA. From initial construction plans to final interior finishes, our team tailors each dwelling for comfortable, convenient, healthy living. As custom ADU/DADU builders, we specialize in:

Detached ADUs "DADU"
These fully equipped, stand-alone homes are built on the same property as the primary residence, providing independent living with all the essentials.

Attached ADUs
These units are attached to the main home and can feature either a private entrance or one shared with the household.

Garage Conversion ADU
Constructed by building an ADU above the garage or converting the garage itself into a comfortable residence.

Basement/Attic ADU
Basement and attic ADUs make use of existing space within the home, converting underutilized areas into fully equipped, independent living quarters.

Backyard FlexSpace
Ranging from 100 to 500 square feet, these versatile ADUs can be shaped into an art studio, gym, office, personal retreat—or even that extra bedroom when you need it.
