“We had the pleasure of working with Tom Ahearn as our project manager on our complete home renovation. Tommy is a consummate professional. Great ideas and designs are just the start- they have to be executed in the field.

“I worked with Benchmark Builders LLC, we did a whole home remodel. They were straightforward to work with and also had a lot of fun. They are a down-to-earth builder that made the process enjoyable. Were their hiccups? Yes, but all in all I would work with them again and I love my home. Nick the owner was a pleasure to work with.”

Green Bay Remodeling
House Extension Professionals in Sonoma, CA
Average rating: 5 out of 5 stars8 August 2019
“It was great working with Zack Ilinetsky and his team. They were professional, communicative, and respectful. They kept the project going and were amazingly on time (5 weeks) to finish the project. There were so many moving parts that Zack kept track of and was on top of, so no delays. All of the inspections were passed with flying colors. He kept the costs down as much as possible, always checking in on how to do things without unnecessarily increasing costs, though he certainly didn't cut corners. He was very thorough and made sure we all were happy with the results. We were very impressed with his work and look forward to using Green Bay Remodeling again for future work on our home.”
Jason McClure Contracting, Inc.
House Extension Professionals in Sonoma, CA
Average rating: 5 out of 5 stars3 March 2016
“My experiences with Jason McClure have all been extremely positive! He is a true professional and a great person to work with. He has done projects in my parents former home that my niece and her family now live in. He did several projects on site. Electrical, plumbing, insulation, lighting, roofing, painting, tile work, bridge repair and other jobs as requested. He has some wonderful ideas, but always listened to what was wanted and offered his expert advice on what would work best. Jason has done projects for me for the past 3 to 4 years. Jason also did some landscaping work at my home as well as a covered area on an existing arbor. He and his family are wonderful and always will have a positive review from me!! My entire family now uses Jason McClure for their contracting needs!! H. Romero”
Contractor 2.0
House Extension Professionals in Sonoma, CA
Average rating: 5 out of 5 stars1 May 2023
“We contracted with Contractor 2.0 to have a small part of our drywall repaired on our ceiling-- they were quick, responsive and did a good job on the repair within 2 days. It was also at an affordable price. Small areas for opportunities for growth would be direct communication with the repair person so that it's easier to communicate about any potential delays. Thanks for the good work!”

Character Builders Inc. General Contractors
House Extension Professionals in Sonoma, CA
Average rating: 5 out of 5 stars26 November 2013
“We purchased a mid-century ranch home and needed Character Builders to remodel two bathrooms, relocate laundry from a utility room off the kitchen to the back area of one of the bathrooms, oversee refinishing wood floors throughout, install new molding on all doors and windows, texture all walls, and supervise complete painting of the whole interior, all with a 7-week deadline so we could move in before the lease ran out on our apartment! The master bathroom design began with a difficult footprint - a long narrow room with no water closet and closet space behind louvered doors along one wall. The remodel of that room was fabulous. Keith delivered everything we wanted in the 'whole house remodel' despite the time crunch we imposed. He would let me know the decisions and selections needed for the next step of the remodel with plenty of time for me to give him my answer. His subcontractors did great work. Keith encountered many things that were unexpected in remodeling a home more than 60 years old; he would have two or three solutions that he would present to us, and would let us choose. I appreciated his collaboration with us most of all.”

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 Sonoma.

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.
