Delta Builders Ltd is a London-based bespoke design and build company specialising in high-quality home extensions that enhance both lifestyle and property value.

With years of experience working across London, we have developed a deep understanding of the city's diverse housing stock, planning regulations, and construction standards.

Our Process

We start every project with a detailed home visit carried out by one of our experienced designers. This allows us to fully understand your requirements, assess the existing structure, and offer practical advice on design possibilities, layouts, and materials.

Quality You Can Trust

Our skilled tradespeople and project managers work to the highest professional standards, using quality materials and proven construction methods.

From the first conversation to the final handover, we are committed to delivering a stress-free experience and a finished extension you can enjoy for years to come.
