"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"OZ-ARI did an excellent job with my recent complete renovation. Quick to respond and great communication. They came highly recommended and provided amazing customer service. I want to give a special shout-out to the construction team because of the attention to detail and care they took with their work. Would definitely work with OZ-ARI again for any future home updates. I couldn't be happier with the results!"

"My wife and I purchased a home built in the ‘70s that was in good condition but in desperate need of a complete remodel. We had a clean, modern style in mind for our growing family and needed an architect to help us turn it into an actual design. That’s where YNG Architects came into play. We selected Yenny Ng and his team for design after interviewing several other firms because during the walk-through (a) he quickly played off and expanded upon our ideas, (b) provided pragmatic insight into the implications to build and construction, and most importantly, (c) had a gentle but confident manner that matched well with our working style. We were not disappointed. Over a period of several months we went through a systematic design process. Yenny and his team listened to our design preferences and took cues from example photos of design elements we admired. He lent his expert opinion and personal perspectives to balance pragmatic build versus splurging where we wanted to splurge (bi-fold doors between the indoor and outdoor space, yay!). He and his team worked well offline where we often exchanged and updated designs by exchanging emails and annotated PDF files—this was very productive as my wife and I both have demanding careers. He and his team also helped us through the city’s permitting process to get the requirements and details done; they were thoughtful and swift in responding to the city’s requests. There were no surprises with the design fees.  In the end, we have a beautiful modern and functional design that fits in well with the neighborhood. Over 65% of the existing home will be remodeled and an additional 30% new living space will be added. My wife and I were very pleased with the outcome and even more excited to see this design come to life for our family. We even have a Phase II project lined up with Yenny and his team to build out the outdoor living space. We would gladly recommend YNG Architects to our friends and family. Now, this also means the construction project will be large and complex and require an experienced general contractor. We did interview other builders but chose Yenny (via YNG Construction) for similar reasons as the design—experience, pragmatism, and working style. We look forward to this next phase of our home remodel."

"One of my relatives recommended to me this home remodeling company after he hired them for his house and they were super happy due to the fantastic job that Best Builders did at his home. At my house I wanted a new patio deck built before the summer will start. Sofia from the main office scheduled me an appointment with one of her people and she sent out Zohar, who worked with me step by step through this entire remodeling project. Zohar is a great guy and a professional person! He made sure that everything is being done exactly as it was promised in the design stage AND each change that he wanted to do (in order to make this project better than it should). The new deck including the covers looks fantastic and it came out much better than I imagined. I’m glad to have worked with Best Builders Group!"

"We found Landmark construction energy crew, after being frustrated in the past from other contractors. From the initial meeting that we had with Charlie, we were impressed. Their values of customer satisfaction and their deliver everything they said. Charlie was the manager of the work and he was on time for all the meetings that we had with him. He was very straight, kindly and motivated to be invited into our house. He came back and took all the measurements that he needed for the kitchen, asked us many questions about what we would like to include in the new kitchen and 3 days after, he brought us a 3D design for us to look at and see how it will most likely look like. It was exciting to see how fast they could generate a nice design. Charlie knew what he’s doing and we were sure he has done this type of jobs many times before. Their prices are reasonable. We wanted our kitchen finished as soon as possible, so we agreed with Charlie to start the following week. That gave us little time to buy all the appliances, hardware, countertops, tiles Etc… Charlie personally went with us to 2 showrooms where we picked out our tiles and countertops. He also helped us to search and buy all the options for the (sink, faucet, hardware and more…). To be honest, I was probably a nightmare type of work. We moved out of our place during the month of the remodeling and we were a little worried that something would go wrong and we would end up on a terrifying remodeling show. Now after this remodeling is over, we can say clearly that is nothing to worry about when Landmark construction energy crew are working at your house. Their workers was clean, friendly, willing to answer questions. I discovered that Charlie visits the job site every few days, but he too sincerely cares about your home. He always called regarding the schedule, timeline or if there was a problem that need to be solved. We asked for changes to the electric wiring after the tiles have been installed. Would I recommend them to others? Absolutely yes. We will refer this company to all our friends."

Custom Home Builders FAQs, answered by experts

Renovating or remodeling an existing structure is usually less expensive than the cost to build a new house. That’s because you can save on the costs of new building materials, laying a foundation, framing the entire building, and installing new materials and utilities throughout the house. However, if a home is in very poor condition or is incredibly old, you could spend more on upgrades and restoration compared to building from scratch.

Custom homes can take an average of 18 months to build, mainly due to the lengthy design process, and most projects take somewhere between 12 and 24 months. When you work with the right custom home builders near you, they can help you map the road ahead and understand what can speed up or delay the timeline. Choosing locally available materials, for example, can speed things up without losing that customized touch.

Modular homes are a type of prefab home. Specifically, manufacturers first build modular homes in sections and then deliver them to the job site. The modules, or sections, are usually at least 70% finished before they arrive on your property.

In comparison, prefab homes arrive in panels or segments, and workers assemble them on-site. Generally speaking, modular homes tend to be more durable, and their consistent construction standards may mean you’ll have an easier time getting conventional home loans.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits. 

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.
