"We were impressed with BD's unique approach—genuine and insightful. The team demonstrated remarkable flexibility and friendliness from start to finish. They have an opinion and take the right approach in sharing it."
MARK & BETH
Private house refurbishment & extension
As our house is in a conservation area, we were concerned that it might prove difficult to get the project through planning. However, BD proved to be knowledgeable of the process and worked very closely with our Planning Officer at every stage, and despite some objections from surrounding residents, planning was awarded.
GEORGE & ROBERT

I cannot speak highly enough of the BD team, and in particular Miriam and Thomas. They are both highly professional, a pleasure to work with and delivered a result – both in terms of building design and construction – far in excess of our expectations.
