Single storey rear kitchen extension - really pleased with the new kitchen. Yuri and his men built the extension and did all of the ground work too and then fitted the kitchen for me. As my existing kitchen plus the new kitchen extension together, is a very unusual shape, the fitting of the new units and appliances would have stumped most builders or kitchen fitters and I know that it was a very difficult job but Yuri fitted everything really well and kept his sense of humour at the same time.
