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

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

A construction-to-permanent loan is the most common type of mortgage used to finance a house teardown and rebuild. These loans include financing for construction costs and convert to a long-term mortgage once construction is complete. Check the terms of the loan closely before beginning work—there are often restrictions requiring you to use licensed contractors for all work.

Typically, architects do not build homes in a hands-on sense of doing the actual framing, roofing, or other building. Architects usually do not have the training and experience to build the homes they design. An architect would need to know how to do the specific trades required to build a house, which is possible but not a common practice. A general contractor or homebuilder typically oversees the actual details of building the house that the architect designs.

The longest part of building a custom home is the design phase. It takes multiple professionals and a ton of work to bring your vision for your dream home to life while sticking to a homebuilding budget and also ensuring everything is built to code. Expect the design phase for a custom home build to take six months to a year.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.
