"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."

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.

Custom Home Builders FAQs, answered by experts

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

It’s typically more cost-effective to move a building along with its accessories than to demolish and rebuild it from scratch. However, that’s only if you can move the accessories without damaging them. However, if you plan to demolish the accessories anyway, it is advisable to do so before the move to save costs.

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.

In most cases, you should get an architect before you hire a builder. An architect will be the one to draw up formal plans for your project, including guidelines and even material lists for your builder to follow during construction. Many architects can even help you find builders, choose one for your project, and negotiate prices. Some are also willing to act as project managers throughout the process, working closely with a builder from start to finish.

Start by researching local contractors with experience in cottage construction. Ask for references, check licensing and insurance, and review completed projects. Compare multiple bids, making sure each includes the same scope of work. A good contractor will communicate clearly, provide a detailed contract, and ensure all work meets code and safety standards.
