"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!"

"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.

"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."

"I can’t say enough good things about D2A Construction and Dani, our project manager. From the very first consultation to the final walkthrough, everything went smoothly. Dani was incredibly professional and always kept us in the loop. The kitchen remodel was done on time and within budget, which was a huge relief. The crew was respectful, polite, and left the place clean every day. I really appreciated how Dani handled every question we had without making us feel like a hassle. The craftsmanship is top-notch — our kitchen looks better than I ever imagined. Highly recommend them if you want a no-stress remodeling experience."

"I am very pleased with the work done by Hic builders. Our initial contact was Josef. He came out and gave us a fair price to replace a wood fence, patio cover, and deck. Materials were sourced and brought in without delay despite supply shortages. My dad is a civil engineer and he noted the wood to be of good quality. He and his workers showed up daily, on-time until the project was completed. Every day the work area was left tidy and cleaned up. We live in a townhome. The only access to the backyard is through the front door and living area. His team covered our furniture and flooring. We will definitely call on Hic Builders in the future and recommend others to do the same."

"I cant explain enough, just how wonderful of an experience we had with Newland. The professionalism and patience that we received throughout the entire process gave us the assurance and value that we hoped we would get from such a demanding job. Our home and family were treated with respect, our ideas were welcomed and now the quality of our home life is forever changed for the better. We began meeting with contractors to see what could be done so that our home could better suit our needs. We met with two other contractors before we met Terry with Newland. After our initial consultation with Terry we knew that Newland would be the company that would help us to make our home dreams a reality. We now have exactly what we wanted in an addition and our home is comfortable and beautiful. Our family of six is now happy and peaceful, and we aren t cramped and crowded for space anymore! The new master bathroom is so stunning and spacious that weve actually spent a significant amount of time in there just visiting with guests when we are showing off the remodel. We have well designed storage spaces, and our staircase fits beautifully in the downstairs space it took up. If we have any home-improvement needs in the future, we will absolutely go with Newland again!"

"This is the second home remodel project that Kyle Beym Home Improvement has done for us. We were so impressed with our exterior home renovation they did a few years ago, that we contacted the company again when we were ready to remodel one of our bathrooms. They were by far the lowest bid, and once again excelled in quality of work and end project. The crew was hardworking and respectful, working long hours and always cleaning up at the end of each day. We were once again pleased with the responsiveness to all questions and changes we made as the remodel was underway, and the bathroom was finished in the time frame that was estimated at the start of the project. The bathroom turned out even better than we had hoped! We are so pleased with the remodel that we can’t wait to do the rest of the bathrooms in our home."

"We recently hired a construction company to complete an addition on our home, and we couldn?t be happier with the results. From the very first consultation to the final walkthrough, their professionalism, transparency, and attention to detail truly stood out. The team took the time to understand our vision and offered thoughtful suggestions that improved both the design and functionality of the new space. Throughout the project, communication was clear and consistent. We always knew what phase we were in, what to expect next, and any questions we had were answered promptly. The quality of workmanship exceeded our expectations. The addition blends seamlessly with the original structure of our home?it looks and feels like it was always meant to be there. The crew was punctual, respectful of our property, and kept the worksite clean and organized each day. We highly recommend this company to anyone considering a home addition or renovation. "

"My husband and I just finished a remodel of our guest house in Sherwood Forest. We used a company called Universal Home Design Inc. The contractor and owner of the company Ouriel Lousky was most professional in every aspect of the job. His crews were timely and most efficient in every way. He had his subcontractors lined up so the job was never lagging behind. I would recommend him to anyone who is planning on a remodel or a renovation. Mary V."

"Used Chris for a refresh on our house several years ago and when we decided to go bigger, reached out to him first. After discussion, decided to go with not only a bigger house, but an ADU and a larger garage this entailed demolishing the existing garage structure stretching the house back 10 feet and adding a second story and building a two-story ADU in our yard. As I imagine with a lot of projects, this large, the city has been difficult to deal with so make sure that you take that into account when doing something like this. We are currently wrapping the ADU and have finished the garage. Looking to move into the ADU to continue the build out of the house. Chris has been phenomenal along the way and has done a great job with change along the way. "

FAQs for addition to existing structure building service projects in Los Alamitos, 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.
