What they build

Design + build under one roof.

Drake Design + Build handles the whole arc of an ADU: architectural plans, interior design, new construction, additions, conversions and the drywall and finish work that makes it feel like home.

⌂
Detached ADUs

New backyard units sized to your lot, your town's rules and your budget, from foundation to final inspection.

▣
Garage, above-garage & basement conversions

Turn existing space into a code-compliant unit, including egress, insulation, plumbing and electrical coordination.

✎
Plans, permits & interior design

Permit-ready drawings and finish selections from the same team that builds it, so nothing gets lost between designer and crew.
