Straight answers

Questions homeowners ask us

If yours isn't here, ask — you'll get the honest answer either way.

Can you build on land I already own?

Yes — that's the heart of what we do. We start by walking the lot with you: access, slope, utilities, and what the land can carry. Then we design a home around it.

How long does a custom build take?

Honestly: most run 10 to 16 months depending on size and site. You get a written schedule before we break ground, and our On-Time Guarantee means we keep it.

What does a custom home cost?

Every home and every lot is different — which is exactly why we start with preconstruction planning: honest feasibility numbers before you commit. And once you sign, our Estimate Guarantee holds: the price you agree to is the price you pay.

Do you handle design, engineering, and permits?

Yes — design through build under one roof, working with residential architects we've partnered with for 15+ years. One team, one schedule, no hand-offs.

We're deciding between a production home and building custom — honest take?

Production is faster and cheaper per square foot. Custom is built around your land and your life, with craftsmanship we guarantee for life. Talk to Greg — he'll tell you straight which one fits your situation, even if the answer isn't us.

Can you tear down our existing house and rebuild on the lot?

Yes — a growing share of our work. When the lot is worth more than the structure, we handle demo, permits, and the new build in one plan.
