"Fantastic! This was our second experience for a remodel with Lou Phillipe and his crew at Stone Age Design and Build and it was smooth and a very satisfying experience. They are highly professional, responsive and do very high quality work. The end product was everything we wanted. The team of Daniel, Carlos, Jose and many others are amazing with very careful attention to detail. They have become like family for us. We can't imagine hiring any other group for a remodel. They are not cheap but the high quality of their work is excellent and they stand by their work. They will come back if anything needs tweaking or adjustment."

"After several long years of designing and permitting our home remodel during the pandemic, we were searching for a good contractor to build out our remodel and second story addition. Avi and David were wonderful; very thorough in explaining the process, answering all of our questions, and settling on a price that was reasonable and within our budget. During the building process, David was very responsive, available, and receptive to changes and last minute decisions made along the way. The project took longer than anticipated and there were some unexpected setbacks, but David and Avi worked quickly to fix issues and keep the project moving forward. At the end of the project they were very responsible about making sure we were satisfied with every last detail before completing the project. Our new home is beautiful and we're very happy with how it turned out, thanks to David and all the crews at So Cal Builders."
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 worked with Nathan to remodel our first house this year. As first-time renovators and first-time home owners, it was a daunting task. Nathan made us feel very well taken care of he has a strong attention to detail, and we felt we knew what we were getting throughout the project. We settled on a price up front for all of the labor, with the promise that even if things came up during the project, Nathan would take care of the complications without changing the price. He kept that guarantee. We ended up expanding our job to include other work, but all of the initial work was done at the promised price with no surprises. We are now living in our renovated house, and we love it. I couldn't imagine organizing such a huge project myself, and we're deeply grateful to have had someone as reliable as Nathan taking care of everything!"

"If you need an addition built on your house, I'd highly recommend you give Creative Remodeling a call. We used them to add a master suite which makes our house much more livable. We've also decided to add decking in the back yard off the the back of the house. Oh, and this was after working with them during Covid on a kitchen and 2 bathrooms. So that makes us repeat, on repeat, on repeat customers. The work is quick, to a good quality, and they listen to what the customer wants and have dealt with the odd snafu without any push back. Highly recommended."

"I'm grateful for the remarkable transformation of my previously awkward 2 bed/1 bath into a fully functional 2 bed/2 bath plus office. After interviewing several companies, I chose HIC Construction because Idan was open-minded, thoughtful, and had good ideas for my first renovation project. Choosing a contractor is like a marriage, and Avi delivered on what was promised, mostly within the expected timeframe. We rearranged plumbing, added a subpanel for a larger kitchen, replaced ducts, added a new furnace, and created two new bathrooms. I appreciate project manager Avi for navigating project issues and assisting in design and investment decisions. I look forward to witnessing your company's continued success."

"I recently worked with HA My Design to build an ADU, and I could not be happier with the results. Golan and his crew were always on time and worked hard to ensure the project was completed within budget. The quality of their work was excellent, and they were quick and efficient. I highly recommend HA My Design for anyone looking to build an ADU. Their one-stop-shop showroom, covering 5000 square feet, made selecting finishes a breeze. I will definitely refer them to friends and family!"

"Our entire kitchen had to be renovated, from floor to ceiling. The Platinum Home Builders staff visited us, listened to our needs, and presented us with options. Though it meant a reduced price, he gave us guidance about what would fit in our space. The responsiveness of Platinum Home Builders was one of the things that really set them apart. Eileen, our project manager, was fast to react to our questions. It makes a significant difference â we had not even felt that we were just another project; they treated us as if we were their only client."

"They added a window and removed the popcorn ceiling and painted a room. They did a real good job with the clean out. The work was good. The only problem I had was with communication due to a language barrier. The work was complete in two or two and a half days. The work is fine. The price was reasonable."

"Trig Builders is an excellent one-stop shop for mainly excellent design, great help in selecting final materials/accessories and mainly for any complete home remodeling. Our master bathroom and kitchen needed to be completely demolished and redesigned. Yossi met with us several times and by listening to us and to what we want to get, he was able to come up with a new concept that included all the ideas and goals of what we wanted to have and his design was very clean, modern while still be within our budget. Yossi also managed and handled all the orders and purchased of the materials and final accessories which caused us to write this review because this was an excellent service. The bathroom was gutted and after the demolition, Yossi and his guys discovered that the floor support beams were damaged so we had to replace them with new ones and to have the floor leveled before they could start the new construction. This problem caused the budget increased by a small cost (Yossi charged us only for the materials) for the overall budget. All the professional people that were involved in the work including the plumber, drywall man, electrician and tile man were excellent and skilled people that executed their part in a very high level of work results. They were very careful about all the cleaning aspect by dropping cloths, plastic wraps for the floors. The kitchen was completely redesigned and Yossi was able to include everything we wanted and needed. He went with us prior to the work and helped us purchasing all the materials appliances. The remodeling job was a week behind the original schedule because of the floor problem and due to few days when we had to leave the house for personal reasons on top of complications in getting the necessary inspections completed. We must mention here that any of the delays was not caused because of Trig Builders fault. We are very happy and satisfied with Yossi, the workers and all the skilled people and mainly Trig Builders as the company and we highly recommend them."

FAQs for addition to existing structure building service projects in Torrance, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
