Baron Construction and Remodeling
House Extension Professionals in San Francisco, CA
Average rating: 5 out of 5 stars28 July 2014
“First they came and give us an estimate that we really liked, we signed the contract to do the kitchen floors. Before they started the job I ask them to give me a price for the complete kitchen remodeling. again we liked the price and we signed the contract (BTW they helped us with financing the job). during the process we found out the electrical wiring needs to be replaced mike gave us very good price on that so we let them do it. they also gave us 3D design rendering that was great, we actually could see how the kitchen will look like.. Roy Mike and the team where very helpful they answered all of our concerns and even when we change things around they where very understanding and helped us to make our dream come true. we where very impressed when all city inspection pass at the first time. we love how our kitchen came out, it looks amazing like it came out of a catalog, its like living in a mention. we will use Baron construction again to do our roof in the in the near future. they did exactly what they promise and above. we are extremely happy that we choose Baron construction and remodeling to do our kitchen.”

Argos Construction
House Extension Professionals in San Francisco, CA
Average rating: 5 out of 5 stars21 January 2016
“I have hired Argos Construction twice, once for a kitchen remodel in our previous apartment, and once for a full remodel in our current house. The fact that I am a repeat customer is best proof that I am happy with Argos Construction and the owner Viktor. Bottom line is that they do quality work at a reasonable price. Viktor is very knowledgable of all aspects of construction and his team is courteous and efficient. My favorite aspect of working with Argos is that Viktor is extremely responsive. He almost always picks up the phone when called. In the rare cases he doesn't he gets back to messages within minutes. To me, this is key when working with a contractor and having your home remodeled. I can only recommend Argos construction, and I will surely be working with them in the future.”
Mayer's Construction and Remodeling
House Extension Professionals in San Francisco, CA
Average rating: 5 out of 5 stars4 December 2022
“Great experience, high value, very reliable and best crew we ever worked with. Mayer’s construction did a home remodeling for us during the last 6 months. It has been a big home remodel for us that took design and build as well. After months spending finding the right company for us, we have choose to work with Mike & Nathan Mayer from Mayer’s construction. A week after finalizing contract we started working with Su & Luis both company’s architect and engineer. We worked on the new plans we agreed and wanted at first and started to have architect drawings ready, when we got into engineering process, both Mayer’s construction and us didn’t know we were suppose to redone so much of the existing footings and reinforce of additional walls as 20 years ago we did a 2nd story addition that was probably made poorly and unprofessional. They were extremely kind and helpful and kept the price as we agreed on and didn’t changed a thing. The plan process and measurements took about a month or so, and finally we were able to submit the plans to the city of San Jose. After getting the permits done and job card set ( overall 5 months of waiting / SJ is a pretty busy city) we got into work schedule and been ready to move out as the entire home going to be demolished. Mike was very organized both managing and scheduling the team, rough materials arrivals, and to us to be fully briefed with details and what we need and when. The process of work was great and on timeline , city did changed a lot during this time period with their inspection delays but it didn’t interrupt with our schedule or timeline due to great management ahead. We just finished our work and we absolutely in love with our new home! New flooring throughout, new kitchen, new bathrooms, complete open floor plan, new stair case, new rooms reconfigured, new paint, new texture, new windows and sliding doors throughout, all new plumbing and electrical. A brand new and beautiful home we got thanks to Mayer’s construction and the team, Mike, Nathan, Raul, Jose and many more who had a added value and did this work absolute best.”

Average rating: 5 out of 5 stars30 October 2017
“Michael Chau from MSJ Construction is our general contractor. We are in the foundation stage of our new construction project in Palo Alto, CA. Michael submitted a detailed, competitive bid and had solid references. We loved his prior experience as a builder for his own state of the art mixed-use property and his contemporary design sensibilities. Most importantly, Michael was prompt in communication and easy to interact with. Those were reasons why we signed him for our project. It certainly helps to have a contractor who is an engineer by trade with prior technology industry experience. Michael uses the latest technology available to builders to share construction progress reports. Communicating with him has been like communicating with colleagues in the office - easy and efficient. He also seems to enjoy the trust and support of material vendors and sub-contractors he works with. Michael joined me on vendor calls / visits, and provided useful input to help make the right trade-offs at our first few decision points so far - e.g. selecting folding doors and radiant heating system. He attends seminars on new building technologies and is open to constant learning. He is also flexible and willing to try new materials and methods to help us realize our architect's and our vision. For e.g. Michael is currently looking for ways to support us on our desire to use the Tesla solar-roof for our project, despite the uncertainty surrounding its first availability. He is creatively thinking ahead to provide schedule flexibility for the Tesla solar-roof via an economical interim roofing option so other project tasks won't be held-up due to lack of weatherproofing. Based on our experience so far, I am happy to recommend MSJ Construction Inc.”

CA Bear Construction
House Extension Professionals in San Francisco, CA
Average rating: 5 out of 5 stars21 July 2023
“Ca Bear is the best, for so many reasons. The first project we did with them was a complete kitchen remodel December 2020. We took down walls, opened up our entire layout and had the best experience ever. A few things that stuck out to us: The speed at which work was completed. So efficient, and that matters when you’re spending a lot of money. Everyday ended with a shop vac sweep and our home was left as clean as it could possibly be. The creative vision that Brenda had for us. I don’t have that lens so thank god for her! The communication that Brenda provided us each day, we always knew what was happening and if there were any changes. Her management was key. Our kitchen was completed 2.5 years ago now, and everyday we sit there and say, “we love our kitchen.” We just love it! After the kitchen we did a closet remodel, again, awesome. Salvador is an incredible wood worker and again, Brenda make the whole process so smooth. A year ago we did a basement and laundry room conversion into a bedroom and laundry/full bathroom. We couldn’t be happier. Everything is still looking amazing, the quality of work is superb. We are so happy. I take my referrals seriously, and I back CA Bear while heartedly. They’re good people, trustworthy and hard working. And to me that matters the most.”

Builder 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 San Francisco.

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. Finally, choose a reputable house extension builder to bring your vision to life.
