Has anyone built one recently? Thermal block with brick skin or cavity wall brick sort of thing. Roof profile that allows plenty of storage without looking like a second storey. I can find prices for prefab stuff, but in York that's baiting the Planners, nothing for conventional construction though. So how much? So many things have become bizarrely expensive in Engerland. Colleague round corner just had a single car size garage added to the end of his house, with a room above and the original roof line extended. Eighty Fucking Grand. "Mostly labour" he said. Good grief a team of 6 blokes working for a month could build an entire fucking house, but lets imagine they only achive a 3x9m 2 storey extension. 960 man hours. <shakes head>
