"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.

"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."

"David and Team recently took on a challenging deck rebuild project at our home. Our home is on a hillside, and also required plans / approvals for the City. David communicated effectively and in detail throughout the process, and did a great job keeping the project on budget and schedule. The Team worked diligently through the issues we encountered, resulting in a beautiful deck that is the highlight of our property. We would recommend Laguna Bay Developing without hesitation!"

"We had an addition built into our home to accommodate our growing family. We were a little nervous about having contractors in our home as I was pregnant at the time but the guys from RS Construction could not have been more professional. They always made sure things were kept clean and safe around the house as they worked. They did a beautiful job with the addition and the price was very fair. I highly recommend their services."

"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."

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.

Handypeople usually don’t hold trade licenses, so they typically aren’t qualified to tackle projects involving installing or making alterations to plumbing or electrical lines. Below are some jobs that a handyperson usually won’t be able to complete:

  • Installing plumbing for a new kitchen or bathroom

  • Replacing plumbing pipes

  • Installing or repairing septic systems

  • Running new electrical wiring

  • Installing a subpanel

While some highly experienced homeowners can frame a house independently, it is not advisable. You will need ample carpentry experience, a team of helpers, and professionals to sign off on your work to meet local building codes. For the safest outcome, we recommend buying or building a house with the guidance of professionals.

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

Yes, you can finance cottage construction through several options. Construction loans provide funds in stages as work progresses, while home equity loans or lines of credit are available if you have existing property. Some lenders offer a combined construction and permanent mortgage. Always review loan terms and payment milestones before committing.
