"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

"Landmark Construction provided us with an amazing customer service throughout the process of the remodeling from start to end. Their prices were very competitive. It doesn't get much better than this. We were having foundation work done on my elderly mother's home in LA. We arranged this remotely via a friend that recommended us to Ezra and Charlie. Ezra took time, care, and patience to make sure that the remodeling will be comfortable with the process and to answer each and every one of our questions. This alone makes us recommend them as highly as possible. Customer service of this level is very very rare today. The work that they did was managed by Charlie. Charlie brought his 3 men team and made sure they will do an amazing work and as fast as they could.  I would use this company again without any hesitation. I'd give 6 stars if I could.

"Team was fabulous to work with, hands down. My vision was to add more living space without adding square footage. Expert Home Builders made it happen. Walls were moved, doors rearranged, pocket door installed, custom shelving, new kitchen with extra seating, and new bathrooms came to life. I felt I was part of the Expert team. My vision and their high standards created my perfect place."

"We purchased the Big Deal to have the Bathroom design.  They came and did the design as expected.  The person they sent out did not sit well with us, and we will not have them back.  We have spoken directly with the provider about the issue.  Additionally, their estimate to do the work was significantly higher than others.  
The 3-D design and ideas they gave us were nice.  I would not use the provider for anything else


Update....the provider has called to try to make this situation right. I appreciate their desire to follow up on negative customer service. We'll see if they follow through with their promises

Update...I was hopefully that the provider would follow through with their promises to make this right, but alas we have not heard back from them. It was as I feared, all talk to get us to change a negative review on this site. Stay away!"

Custom Home Builders FAQs, answered by experts

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.

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

An A-frame home can be cheaper to build than a traditional house, but that is not always a given. Prices can be fairly similar in some cases, depending on the location, design, and necessary site preparation. Costs for an A-frame typically run between $100 to $200 per square foot, which is comparable to the cost of a traditional home. The cost of an A-frame can come in under those numbers if you opt for a prefabricated kit.

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

Above all, the downside to building a new house is a longer timeline. You need several months to finish the build, depending on the supply chain and labor availability in the meantime. Building a home compared to buying one is also more expensive, both in the building process and when it comes to mortgage rates and property taxes.
