Denver Custom ADU Builder

from our clients

We worked with Denver Custom ADU on two projects across two homes in Denver—converting our garage into a beautiful office and fitness space, and a basement renovation. His work was exceptional.

— Virginia S.

Matthew helped me with a complete design & build project for a small ADU at our house in Denver. He was involved with everything from the initial design phase, to linking up with an architect, choosing materials & finishes, everything. He made the process super easy and transparent. Pricing was fair, build quality was excellent. Timeline was right on schedule. I’d definitely recommend him and would work with him and his crew again!

— Ari M.

We had them do a total design, tear down, and remodel job, and they did an exceptional job – brought the whole property back to life. This was an old house from the 1800s, so nothing was simple and he found clever ways to work with it to make it shine again. Did an excellent job and he even tells some mediocre jokes from time to time.

— Stephen F.

What sets us apart

A clear timeline & set budget

We provide fixed budgets tied to defined scopes. If you request a change, we adjust transparently. Otherwise, what we quote is what you pay and our schedule remains set. That’s our No Surprises Guarantee.

Pay-As-You-Go

You sign a separate contract for design and construction and then we only bill monthly on work we’ve actually done. No large upfront deposits or out-of-pocket expenses. 

Comprehensive Permitting Support

We approach permitting the same way we approach construction: proactively. We anticipate red flags before they become setbacks. We maintain communication with reviewers. We prepare complete, coordinated submittals — because speed without shortcuts is possible when you know what you’re doing.

Regular & proactive communication

Our “step-ahead” communication ensures you always know exactly what’s happening with your project what’s next. We’ll let you know when you can expect us, which days might be noisy and where we’ll be storing everything so that you can plan accordingly.
