"Matthew Bruce exceeded our expectations. Our 92-year-old dad fell while using the bathroom and injured himself. We needed an immediate response to make the bathroom safe. Matthew responded to my request very quickly. He asked questions about the situation that showed he had the expertise we needed. He came to the house within a day of agreeing to perform the work and completed the most urgent task that day. He needed other tools to complete the installation of the grab bar drilled into the shower tiles, so he had to return at a later time. He communicated clearly when he could return and completed the task. Additionally, he cleaned up after his work and was pleasant to workMatthew Bruce exceeded our expectations.

"Noah and his team are truly wonderful to work with. Noah kept in close contact with us and was able to add items we decided on during the project. We couldn’t be happier with the final product. We have already contracted Chumbley Construction to remodel our bathroom based on this experience."

Home Building FAQs, answered by experts

Construction typically takes 3-6 months, including site preparation and assembly.

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.

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

It usually takes around four to six months to build and install a modular home, although your timeline could go up to around eight months if there are delays in the manufacturing or permitting process. Heavy site preparation and foundation pouring can extend that timeline if you need them, as can customizations you want for your modular home. Your modular home company should be able to provide an estimate for the construction timeline before you sign any contracts or agree to any work.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.
