“We have known and relied on Brian Knowlton Builders for many years.   As the former owners of ‘Busketts Lawn Hotel’ Woodlands for 38 + years!  We used Brian Knowlton Builders for several extentions, modifications, and improvements at the Hotel, and the work was always efficently planned, organized, consistant and well supervised.

We sold the Hotel in 2007 and moved to a cosy but very out of date cottage in Netley Marsh, and started planning to improve the building and had no hesitation in contacting Brian Knowlton Builders to do the work for us, as we knew we would get a very good job done at a reasonable price and the work would be completed in the time schedule given.  We had a few hiccoughs along the way with planning, which they took care of, to our total satisfaction.

From our experience, we would have no hesitation in recommending Brian Knowlton Builders for quality building services.”
