Biscuit Joinery – Custom ADU

He wanted a woodshop. She wanted a guest room. An energy-efficient custom ADU in the backyard of their Old Town Fort Collins home became the perfect solution to house both.

ABOUT THIS CUSTOM ADU

This custom ADU incorporated Passive House principles for the construction, which included using energy-efficient windows from local window manufacturer Alpen and SIGA Majrex intuitive smart vapor barrier. This makes the ADU a cozy place to work and stay in during the winter months while only needing limited heating, and it’s comfortable in the summer without air conditioning.

On the exterior, wood siding matches elements on the main house, while low-maintenance Corten steel accents and a metal roof give the space an industrial look. Double doors on the shop side open wide for unloading woodworking supplies that will be used by the homeowner to build cabinets and a wall bed to complete the guest space, creating a personalized touch from the woodworker himself.
