  John Whitmore - Director   I started out 29 years ago as an apprentice learning and gaining qualifications in all areas of the building industry. I have a good knowledge of all aspects of the trade and feel lucky to say that even now after so many years I still love the work we do and I think this shows in end product.  I've been in the building industry from the age of 16, starting out as an apprentice heating engineer. Having gained qualifications in domestic as well as commercial, I began working on projects which gave me a better understanding of the building industry as a whole. I carried out many small jobs which led on to larger projects, running teams of contractors from brick layers, plasterers, electricians and working with local planning departments and district surveyors.
