The side return house extensions and single-storey ones are cheaper than a double-storey extension. Moreover, your extension cost will depend on the design you want, the size of your dream home, the planning organization, and your budget. Barnes builders take care of your budget by planning the purchase of materials and managing working hours. As the architectural plans are drawn up and project costs are controlled, you’ll have more savings from extending your home. There’s also a project manager appointed to ensure that there’s efficient project management. Spend less to get more value when you hire professional builders in Barnes for your home refurbishments.


You get a team that does not compromise on the quality and satisfaction of its clients. Their diligence, craftsmanship, and commitment to quality work makes the team stand out from any other building company. You also get FMB fully insured builders and NICEIC-approved contractors providing you with a completion certificate and a structural guarantee of 15 years on construction projects.
