"The remodeling of my guest bath went very smoothly. I had few ideas as to what I wanted, but thanks to Nathan's design help, I was able to select the items that fit my concept. Many reviews talk mainly about the job and the results, but there is one important area that is often neglected: the working crew. Without exception his guys, besides being highly competent, were both respectful and considerate at all times. I strongly recommend this company!"

"Avi helped me go over my existing construction plans and was really thorough and helpful. Great customer service. He gave me a solid quote and a reasonable price for the job."
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.

"It went exceptionally well. The Project Manager, Jonathan, was very knowledgeable and patient -- it took us a couple of months to get ready for the project. Jonathan is reliable, competent, easy to work with, and will make sure the job gets done right. He and Supreme Remodeling, Inc. would make a great choice for your next renovation or new construction project."

"I decided to convert my garage into a ADU building, to get extra space. I worked with Kris and his Architect from Creative Home Remodeling on the design and plans. After we got the plans approved back from the city Kris started to build my new space based on his design. We added a small kitchen with a living space and nice bathroom. It has become a very nice place and I love it. Thank you Kris and Creative Home Remodeling."

"We just finished a four bedroom/ three bathroom full remodel in Santa Monica. We are very happy with the end result. Nathan, who is the owner, was very involved in all phases of the job. Nathan got the job done on time. The workmanship and attention to detail was great. He had good communication and relationship with his team. Whenever we had a concern or question, Nathan was easy to get a hold of and handled it quickly. We were worried about the process of a remodel with all the stories you hear about bad experiences. But Nathan made this so easy on us and we would definitely use him for any future projects."

"We needed to do a kitchen remodel for a while now so we did a massive research online and by asking friends and family in our area. After meeting with all of them and explaining to them what are we looking for, what we want to do and mainly what is our budget. We received estimates from all the contractors that we met and we selected Trig Builders because Yossi was the most competitively priced and the referrals that we got on him and his company were very positive. Yossi and the workers were very easy people to work and to deal with and Yossi designed the kitchen exactly the way we wanted it with some nice additions of things that we didn’t think we will get. His suggestions about the new kitchen layout, where and what materials to buy were very helpful. Also, his advises and recommendation on where to buy the cabinets, lightings, plumbing and appliances saved us a lot of money. The end result of the new kitchen was perfect and one of the things that added a huge plus before we hired them was the warranty that included in the price of the work that they did."

"My husband and I hired A&A Construction for multiple projects in our condo: fireplace modernization, laundry room conversion, bathroom renovation and living room cabinetry build-ins installation. The scope of all projects required a lot of design and planning, ranging from cabinetry design to running electrical and plumbing connections, and so much more! The results are stunning. Our place looks like a completely new unit that someone just built. Arnold and Devon are knowledgable and experienced consultants who gave us lots of ideas on how to improve our place and give it more function. The entire team was professional, courteous and punctual. They catered patiently to our requests as we made some changes during the entire renovation process. Overall, we had a great experience working with the A&A team and we would hire them again in the future. "

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