Hello, If anyone is looking for a builder outside of the ED forum usual suspects who are v busy and also, in my experience, a little higher in price because of the fame, maybe. We've used a firm, Creative Living SE, who were found via check a trade and who have been excellent. V courteous, engaged with neighbours, friendly crew, mopped every day and have been the smallest interference to us. 6 weeks completion for single rear extension. Even booked a cleaner to tidy up our flat at the end. Ken's number is 07988 991020.
