Architecture- 15 Aug 2020
Neil has not been to the moon, but he has supplied us with some amazing drawings for our extension, he was more than happy to listen to our thoughts and give us lots of options for our extension. The planning application went through in record time and Neil took care of everything for us. He was only slightly more expensive than others we spoke to but his standards are miles above the rest. Our builders have said that they do not need to think about the build as the instruction on our drawings are so easy to follow. Thank you Neil, much appreciated.

Extensions- 10 Jan 2016
We are delighted with the fantastic single storey extension that Rob and his team have built for us, creating a wonderful kitchen/diner/lounge and utility. Nothing was too much trouble for them and their dedication to providing a home we wanted (not what was easier for them) was excellent. They were punctual, competent, polite, hard working, tidy and fun to have around. They provided good ideas to help us through any difficulties we had in making decisions on areas we hadn't thought about when planning the extension. The build has been finished to a high standard and we now have the living area that we have always wanted. Everybody who visits is impressed with the work and has asked for Centurion's details. Thank you Rob, Paul and Martin for our fabulous new home.

Overall they did a very good job and the end result was better than expected. They were a bit untidy, so something to keep an eye on. However they were very responsive to any queries I had.

What qualifications and experience do you have as an extension builder in Malmesbury?

An extension builder in Malmesbury should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Malmesbury?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Malmesbury extension builder’s ability to deliver a result that meets your expectations.
