Hello, REPLY BY EMAIL ONLY PLEASE. We are considering having either a full extension or lean-to conservatory to the rear of our terraced house. Rather than have a parade of sales reps coming in and out of our house we would ideally like a ballpark figure to establish if it is financially feasible. Extension/conservatory measurements: 6mtrs x 2.1mtr Solid walls to sides, dwarf walls to the front with double opening doors AND GLAZED PANELS EITHER SIDE OF DOOR. Floor make up approx 400mm to be level with kitchen. Some pipework to be boxed in and all internal walls plastered. Electrics and plumbing to be carried out by myself. Regards, Michael Bush
