MY Home Builders Inc.
House Extension Professionals in Los Angeles, CA
Average rating: 5 out of 5 stars15 February 2016
“It really was absolutely wonderful having My Home Builders transform our never- been-updated kitchen &baths into simply gorgeous, functional, light filled spaces that are now the envy of our family, friends, and neighbors. During our first meeting with Roy, he listened carefully to my color preferences and lengthy wish list in order to come up with a design plan for each of my three rooms. and then, at our next meeting, I was able to view 3D computer images of how the finished rooms would look like, and to say I was astonished to see he'd included every item on my wish list. starting From demo to completion - always ahead of schedule. and by the way - Roy kept us well Informed about every step of the work. This was super important to us. He came early each day to meet with the work crew and us, and was always available by phone / text as well. The project foreman, and his entire crew were super friendly and polite, so it was a pleasure having them in our home each and every day. And true to his word, Roy made certain we were both satisfied with every detail before the job was fully completed. - Since I tend to be very particular, I was thrilled to work with such a company that also shares my views of a job well done!! It's superior quality work, at not a penny more than the contracted price that was completed on time. My Home Builders is the best choice you can make for all your remodeling needs. Good luck in your decision making”

“We wanted to remodel the kitchen and my brother recommended calling Pure Builders. He said Pure Builders were real professionals. Their designers were really knowledgeable. They were very careful with the flow of the design. Eli from Pure Builders really listened to what we wanted. We saw the 3D design plan he came up with and we hired them. The design blended with the existing decor of our house. Eli really puts in a lot of effort with the design. When they started their crews were really good. They checked in with us and answered all our questions as the kitchen remodeling progressed. Good company for your remodeling projects! Thanks, Eli!”

“I worked with Synthesis on the design and construction of my home and I could not be more pleased with how the project came out. They are very professional, honest and their attention to detail can be clearly seen in every aspect of their work. Every person that has walked through my home has always commented on their work and many have asked me for their contact information. I would highly recommend them for your next project.”

“I am currently working with Stephen Gabor and The Gabor Design Group on a backyard landscape and home add on project. Stephen and his team are extremely professional, organized and responsive. I am in love with the work they have done at my home so far and cannot wait for the finished product. As a homeowner since 1999, I have been through multiple renovations and worked with several contractors and have never had a good experience until the Gabor Design Group. Exceeded all of my expectations!!”
Kofler Design Build
House Extension Professionals in Los Angeles, CA
Average rating: 5 out of 5 stars28 December 2018
“I have been living In Mar-vista CA/West LA area for over 30 years. My house is about 3,000 Square feet and I have procrastinated renovating it for a very long time. I was very concerned with finding a reputable construction company as I heard so many horror stories related to this industry. I was so lucky to be referred to “kofler design build” by a close friend I trusted very much. I met with Asaf, and with no time my worries fated away. He asked me all the right questions, took notes and open my eyes to the possibilities at hand. What I liked most was that he wasn’t pushy in any fashion and told me to take my time and think things through. My main focus was on the kitchen, flooring, master bath and powder room. Within two days, Asaf emailed me a detailed proposal that fully explained the project. He of course included the total price as well as a fair stage payment process. I called him up and told him “Let’s do it”. He sent me all the documents to review and had me signed them via DocSign, at my own privacy, which was another very comforting factor. (Especially after having a guy from a different company that wouldn’t leave until I signed his contract – Terrible) After several days we met with his amazing cabinet maker to work on the kitchen design and schedule the official start date. A week later demolition started. I never imagine anyone paying so much attention to cover walls, floors, doors etc.. before the they start demolition. His crew finished all the demolition, haul away and cleaning up in one day! (WOW) The crew members and his foreman were at the house every day at 7:45 am, waiting to come in at 8:00 am sharp. The work was professional and the attention to detail was remarkable. Cabinets came out better than I thought. We had one issue with the counter tops, where the island counter broke. Asaf took care of it right away and three days later they came back to install a new one, no questions asked. Asaf Helped me with all the fixtures selection and was able to save me quite a bit of money on most of them including all the tiles. One thing I really appreciated was the fact that each day about 20/30 minutes before they finished for the day, his workers stopped everything and clean-up the work area. I am very sensitive to dust and so I found this incredibly thoughtful. The project was done in just under six weeks about a week before schedule. I don’t have much experience in renovating so it’s hard for me to compare this company to other companies, but I can most definitely say that my experience exceeded my expectations and was very, very good!

US Home Developers Inc.
House Extension Professionals in Los Angeles, CA
Average rating: 5 out of 5 stars3 July 2014
“My family and I pooled our money together to get me a new condominium in Reseda, CA. We got it for an incredibly good price, but it needed extensive remodeling work. I needed to remove the carpet and replace it with wooden tiles, re-paint the entire place, fix up the wiring, and the plumbing and I needed to redo the entire bathroom. It was no easy matter. What was even more problematic was that the current house I was living in is being foreclosed on and I had roughly 3 months to move out. My step mom knew about US Home Developers through a friend of hers who hired the company before, so she pressured me to look into them. I was sort of new to the whole experience but US Home Developers made it extremely easy. They were up front about the cost and time estimates, and were willing to work with me to provide the best solutions for the limited budget I had. Every day I would come to the condo after work and see what has progressed. I was constantly amazed at the speed by which everything was taken care of. The bathroom was the longest and hardest part because of all the necessary plumbing. They redid the tiles in the kitchen, and replaced all the carpets with the hardwood flooring that I wanted. They actually ended up finishing 2 weeks earlier than I had to move out and I was thrilled because it game a lot of time to move in and get settled. As someone who was entirely new to the experience of having a remodeling job done, I was really amazed at how easy, and great US Home Developers has made the experience.”

“We have worked and collaborated with Kim and Bauer Design Group on several residential projects since 2008. Kim and her team have worked on designs ranging from a single room up to multi-million dollar whole house projects that encompassed ground up construction and specifications of finishes, furnishings and fixtures for the interiors and exteriors. It is obvious that when working with her that Kim takes pride in listening to her clients and designing to their wants and needs not to a product or style that might be in her business’ best interest. She has always been very professional in her dealings with both her clients, business partners and suppliers. Kim’s best attributes include her comprehensive understanding of the entire design and construction process, her project planning skills and working to make sure even the smallest details are covered. Kim definitely has an eye for current styles and trends and she is undoubtedly one of the top designers we have worked with in the Orange County/Inland Empire area. Kim is a pleasure to work with and we highly recommend her services!”

Design and Build Company FAQs
A house extension is a construction process that involves expanding the footprint of your existing home. This could be extending outwards, either to the side or rear of the house, or upwards by adding another storey. House extensions provide extra living space and can significantly increase the value of your property.

House extensions can be categorised based on direction, structure and function. The main types include rear extensions, side return extensions, wrap-around extensions, and double or single-storey extensions. More specific ones could be kitchen extensions, loft conversions, basement conversions, garage conversions or conservatories. Select the type that best suits your property and meets your space needs, if you are unsure, speaking with a local home extension builder in Los Angeles.

Generally, house extensions are worth the investment. They provide additional living space and can dramatically increase the resale value of your home, often covering the initial investment cost. However, plan carefully and choose a reputable house extension builder to ensure a high-quality build that will add value to your property.

The cost of a house extension can vary significantly based on several factors, such as the size, complexity of the design, quality of materials used, and geographical location. However, as a rough estimate, a single-storey extension can range from £1,000 to £2,000 per square metre, whereas a two-storey extension can start at around £1,500 per square metre.

Planning a house extension involves several stages, including idea generation, design, planning permission, and construction. Consult with a house extension architect to create a design based on your needs and budget. Ensure to check with your local council about planning permissions.
