"My husband and I had spent 13 years remodeling our 1873 house by ourselves. When it came time to do our dream project of adding a sunroom, finding a contractor to do the work instead of doing it ourselves was a very important decision to us. We met with several contractors and knew instantly that John and his son Nate at Addition Doctors were the people we wanted taking on this project. John and Nate were so great to work with. They were the only company we met with who gave us a computer generated model of what the project would look like so we had a very clear vision of the end product. They were the only company to quote us the project under the budget we told them we had to work with. They kept us up to date at every step of the project and there were never any surprises about cost or timing. They had great ideas for the project when we weren't exactly sure what should or could be done. We love our finished sunroom. The quality of work and service they gave was excellent. We would highly recommend Addition Doctors for anyone who is looking to have quality work done to their home."

"Des Moines Area Roofing was professional, trustworthy, and demonstrated excellent attention to detail from initial contact to job completion. Cleanup was so thorough that the next day you wouldn't even know that such a major project had taken place. It has been 2 weeks since the new roofs and we haven't seen even one stray nail left behind (and they did a complete tear down to both buildings, right down to the wood). An excellent company with which to do business. I offer my highest possible recommendation."

"I was very impressed with Sentri Homes - their customer service was excellent. They sent a subcontractor to install some vinyl laminate in my bathroom and he ended up getting glue all over the carpet in our bedroom. The sub ended up ghosting both me and Sentri, leaving me stuck with a ruined carpet. Sentri stuck with me for over a month to get the carpet replaced with the identical original and to get the vinyl job 100% completed. The carpet was a Home Depot exclusive and Sentri handled everything with them. I will be using Sentri for a much bigger renovation I have coming up soon, because I know that they will make sure everything gets done right no matter what problems come up. The vinyl looks great too."

Custom Home Builders FAQs, answered by experts

Ultimately, a work warranty is only as reliable as the contractor you’ve hired. That’s why trust and reputation are such important factors, in addition to having a solid contract and confirming appropriate licensing, insurance, and bonding. When looking for a contractor, it’s a good idea to read online reviews and ratings to see what kind of experience past customers have had. Issues with your contractor can make for an unsatisfying renovation process, but a reliable contractor can make the process go as smoothly as possible.

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.

A carriage house is a freestanding building, while a townhouse is connected to other units. A townhouse is a full single-family home and typically shares a parcel of land with other connected homes. A carriage house is rarely used as the sole single-family home on a property and is most often an additional building sharing property with a traditional single-family home. 

The average cost to build a modular home is around $270,000, and most modular homes total between $180,000 and $360,000. Of course, this price varies significantly by location, and the price tends to follow the cost of living in the area. There are quite a few other factors at play that can affect your pricing, including the following:

  • Number of bedrooms and bathrooms

  • Site preparation, including land clearing and leveling

  • Type of foundation

  • Utility connections

  • Cost of building permits

Remodeling a house is often less expensive than building a new house. You can expect to pay an average of $100 per square foot when you are remodeling. The cost to build a house averages about $150 per square foot. When remodeling, though, some rooms cost more than $100 per square foot and some cost less. Use a home renovation cost estimator to accurately estimate your remodeling costs.
