We used Mr Gaunt (BJM Design and Build) for our loft extension and were delighted with both the quality of the finished product and his transparent and fair pricing.  His team were polite and professional and the house was always left tidy and clean.  Mick was able to advise and discuss with us any changes to ensure that we both maximised the space and gave us the living area that suited our needs and our family.

We have gone on to use Mick and his team for a patio extension and bathroom revamp and once again got the spaces we wanted that worked for the areas available.

We will now only be using BJM Design and Build for any other building projects in the future and I have told Mick that he is not allowed to retire until our house alternations are complete!

We always found Mick to be approachable and even when we had questions about part of the build, he would happily discuss our concerns or desired changes with us and was both willing to change when needed or advise us as to the impact of changes.  This was also true of pricing.  We changed our minds about some doors and where an interior wall was to go and Mick made sure that we knew the financial impact on this before proceeding. 

 Mick and his team have helped us create the home we want at a fair and transparent price with a professional finish
