Our Process
What to expect
-
We meet to understand your goals, site, and budget — and walk through how we work, what's possible, and the next steps.
-
Together with your architect (or ours), we develop scope, drawings, finishes, and a clear path to permit.
-
A line-item proposal and contract aligned with your scope, schedule, and budget — clear pricing, no surprises.
-
Organized site management, weekly progress updates, and a single point of accountability throughout the build.
-
A detailed punch list, final cleanup, and warranty documentation before keys change hands.
