We are a building company based in Banstead, Surrey. We offer a full design and build service from conception through to completion with our own Architectural Designers and skilled tradesmen accommodating all aspects of the build process.

Architectural Design

Our Architectural Team are passionate about residential design and have an in-depth knowledge of both the construction and building industry.


We've built in excess of 130 extensions. As well as creating exceptional extensions, we also guide our customers by giving regulation advice.

Interior Design

We advise on all areas of the design process taking into consideration your requirements to give us a clear picture of exactly what you need.


Most property extensions require at least some refurbishment work so again, Bentley’s has considerable experience and expertise in this area.


With initial design by our Architectural Team and on-going modifications managed by our Project Manager, you are in good hands.


With two teams of experienced landscapers, we are as efficient providing foundations for buildings as we are at laying or relaying drives and patios.

I am delighted with my extension which has transformed my house, creating 2 extra bedrooms, dressing room, en-suite, utility and extending the family room. Reliable and punctual, Bentleys have produced a quality finish to time.

Just quick e mail to say thank you for completing the conservatory at Westcombe. Thanks to your teams input it certainly looks "a million dollars". I have no hesitation on recommending you guys to other potential customers planning building works.

- Andy Grainger

The quality of 2 Bentley's work is excellent, all the tradesmen are skilled, polite and helpful, and get on with their work with pride and efficiency, and they leave the site in a tidy state at the end of each day. The work is well managed by Paul and Andy and they are always available to talk to.

"We are so glad we chose Bentley Brothers Ltd above several local competitors, to modify our home. When we asked for a quote, we were given a very clear and concise list of the work to be done, with individual prices for each step, so there were no nasty surprises at the end of the job."

- Pauline and David Guy

"Thanks to your team for everything that you’ve done for us over the last few weeks. I have been impressed by not only the workmanship, but the attention to detail, the professional way in which you have all approached the job and the friendly and courteous manner of all the staff and contractors."

- Bob Marchbanks
