CRB Building & Roofing are true specialists in extending your property. Home extensions are a real art and are generally considered to be far more difficult than new builds. A good home extension builder should have the right skills and expertise to marry your new building into your existing building. We spend a long time with our clients ensuring we get just the right bricks for the walls and tiles for the roof, and even use little tricks like re-using already weathered materials reclaimed from the existing building to make it look perfect. Take a look at these case studies to see how we blend extensions in to both modern (Seaford Extension hyperlink) and period (Granary Extension) buildings. Of course extensions don’t always have to blend in and we are very good at creating striking extensions using modern materials like Monocuche through coloured render, architectural grey aluminium windows and all metal fascia details with hidden gutters.

One of CRB's key facets is the combination of both a building and roofing skill base. This means our own distinct teams construct the timber roof structure and complete the roof finishes. This joined up approach allows us to offer quicker projects (no waiting around for the roofers to turn up!) but also allows us to design better watertight details as the roofers and carpenters work alongside each other to ensure the best design and outcome for every project.

We have built house extensions starting from under £10,000 right up to £400,000 and can help with everything from design, planning, budgeting and building regulations. We offer a free site meeting to discuss the process with you and set you on the right path, offering access to approved and vetted designers, architects, engineers and surveyors. If you’re considering a house extension and are looking for a quality builder, call us for your free site visit and appraisal.


CRB is a family-owned and managed company with a staff of 16 full-time employees, supported by a network of specialist sub-contractors.
