Most of what goes wrong on a build was decided before anyone broke ground. My job is to be in the room before that.

FAQs
FAQs
Straight answers to the questions homeowners and architects ask us most, from budget to timeline to how we work with your architect.

What is pre-construction?
Pre-construction is the work before a construction contract: pricing the design while it can still change, writing our assumptions next to each line, and reviewing constructability. You get a line-item cost model before you commit to building.

What does a custom home cost in Boulder?
Costs vary with site conditions, design complexity, and finish level. Projects typically begin around $700 per square foot, with highly design-driven homes often exceeding $1,000 per square foot.

Cost-plus vs fixed-price construction
A fixed price on an unfinished design is a guess with a margin on top. We work cost-plus with an open book: you see actual costs and our fee, and the monthly cost report we see is the one you see, unedited.

How does Fernhill work with architects?
We join the team early, price the design as it develops, and flag constructability issues while they are still drawing-table decisions. The architect keeps design authority; we keep the budget honest.

Why involve a builder early in design?
Most of a project’s cost is decided before the drawings are finished. With a builder in the room early, the budget can shape the design instead of surprising it after permits.
