"It gives me great pleasure to write this review for Unison Builds LLC. Chris and his team handled the complete interior and exterior renovation of our 7,500 square feet office building. Their work included adding seven new offices, a gorgeous marble kitchen and dining room, a wonderful reception area, an executive conference room with a 14-foot table, the CEO's new office, and nearly everything else. He is a reliable builder. His team takes great pride in what they do. And the work proceeded even faster than we expected."

Customers say: Terrific value

"Colorado Paradise Builders were responsive when we asked for a proposal to finish our basement. They created a thorough proposal with a price, timeline and specific details on the project. They followed through on everything in a timely manner. Everything cost what it was supposed to cost; their tradesmen were courteous and clean, and they completed the project on time. I would not hesitate to recommend them to a friend or use them again for another home project."

Custom Home Builders FAQs, answered by experts

Framing is often the most expensive phase of building a house because it’s time-consuming and requires a lot of materials. It costs between $20,000 and $50,000 on average, depending on materials and labor costs. Before construction begins, it’s possible that purchasing land is the priciest step in the process. Some plots of land sell for $3,000, while others cost upwards of $150,000.

How long it takes to build a custom home or rebuild a home after a disaster varies depending on many factors, but averages between seven and 14 months. Smaller homes or homes that don’t need a re-poured foundation may take less time to build than larger homes or homes without an existing foundation. Material availability, contractor schedules, and permit and inspection timelines can all affect how long your house takes to build.

It’s typically more cost-effective to move a building along with its accessories than to demolish and rebuild it from scratch. However, that’s only if you can move the accessories without damaging them. However, if you plan to demolish the accessories anyway, it is advisable to do so before the move to save costs.

One of the best ways to negotiate with a homebuilder is to forgo price reductions. Instead, negotiate over upgrades and incentives, as many builders are more willing to go down that road than to decrease their own fee. Even if they were willing to take a cut, a reputable homebuilder often knows their worth, so a willingness to negotiate could be a red flag. Beyond that, builders are typically willing to negotiate closing costs instead of offering a discount on the base price.

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.
