"Our experience with Suj and So Cal Builders & design was very pleasant. They executed a high quality upgrade to our prior home before we sold/upgraded. We did not want anyone else to renovate our new house. Every step of the remodel was handled in a timely manner. And, honestly, Suj is quite humorous; he creates a very nice environment to be around for his team and clientele."
Completely renovating both the guest and master bathrooms. In the master bathroom, we're installing a spacious walk-in shower featuring dual black-finished shower heads, elegant floating benches, and marble wall tiles. Meanwhile, the guest bathroom will have a sleek built-in tub and stylish hexagon tiles.
This project involved adding a new master bathroom to the existing house. The shower features sleek white subway tiles complemented by striking black fixtures and shower door hardware. The bathroom floor is adorned with elegant white marble tiles, providing a seamless and luxurious finish. A white shaker vanity topped with a white marble countertop completes the space, creating a clean and sophisticated look.

Customers say: True professional

"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."

"David and Efrain did an amazing job converting our oversized 2 car garage into a one bedroom apartment. They were very attentive, cost conscious and efficient! They were on hand monitoring the subcontractors and making sure the job was done correctly. They did a great job and we are very gratefully for their hard work!"

"My experience with LA Expert Builders was awesome. I went with them on my bathroom remodel and they did a high quality work, did everything as I requested, as they promised and all that at very reasonable costs. Nir and his crew were great to work with, always on time, clean, polite and professional. I really like how my bathroom turned out, it's very beautiful! Thank you LA Expert Builders!"

Custom Home Builders FAQs, answered by experts

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

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.

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.

How long it takes to build a custom home or rebuild a home after a disaster varies depending on many factors, but averages between seven and 14 months. Smaller homes or homes that don’t need a re-poured foundation may take less time to build than larger homes or homes without an existing foundation. Material availability, contractor schedules, and permit and inspection timelines can all affect how long your house takes to build.

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.
