"Adam did a fantastic job from the beginning to end. He communicated along the way and helped make decisions, giving us various options. We appreciated Adamâ s integrity and excellent craftsmanship. He made our house a home and treated us like family rather than just another customer. We will use Adam for other projects and highly recommend him!"

"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."

"We are so happy we picked LEC for our custom home build. We talked to many GCs and literally cannot say enough about our experience with them. We had a very specific design in mind and they delivered 100% for a reasonable price point and faster than any of our neighbors were built. Highly recommend!"

Custom Home Builders FAQs, answered by experts

Builder-grade is one of two types of stock cabinets, whereas semi-custom designs allow homeowners some control over the color, finish, or hardware on their cabinets. Stock cabinets are sold in construction-grade and builder-grade designs. Construction-grade cabinets are usually made from inexpensive medium-density fiberboard, which is prone to moisture damage, whereas builder-grade models are a step up with higher-quality materials. Construction-grade designs are the most common type of cabinets in America.

Modular homes last an average of between 50 and 75 years, and high-quality modular homes can last for 100 years with proper maintenance. For comparison, a standard home lasts 50 to 100 years and can push to 150 or longer with good maintenance. Modular homes provide better long-term value in that they are significantly more affordable and can last almost as long, but some buyers are wary of modular home longevity, so the actual value if you sell could be lower.

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.

The term “cottage” is subjective, so there’s no rigid definition, but it generally refers to a small home with simple and purposeful architecture that embraces nature and focuses on charm over everything else. Cottages are typically 1 or 1 1/2-stories tall, usually with gabled roofs, and are built out of natural materials that help make the structure a part of the surrounding nature rather than something that stands out from it. A big part of what makes a cottage a cottage is the decor, which includes natural materials from the nearby area.

Handypeople usually don’t hold trade licenses, so they typically aren’t qualified to tackle projects involving installing or making alterations to plumbing or electrical lines. Below are some jobs that a handyperson usually won’t be able to complete:

  • Installing plumbing for a new kitchen or bathroom

  • Replacing plumbing pipes

  • Installing or repairing septic systems

  • Running new electrical wiring

  • Installing a subpanel
