We had a lean to garage fitted and the fitters said that it was about as big as they would normally build a lean to garage, although they'd built much larger stand-alone garages. We'd already had the ground works done which took a couple of weeks. The garage was delivered and erected in about 5 hours. It looks neat and tidy and our car fits in easily (unlike the garage at our previous house). There were a few gaps in the mastic put between the panels, but they did leave a tube for us, so we could tidy that up ourselves. I put a mortar fillet on the inside as directed but the rain still came through a bit as damp patches. This might improve as all the concrete cures. I also painted the fillet with a bitumen paint which has helped. All in all, a nice job . Sharon in the office was very helpful throughout the buying process and I'd be happy to use Nucrete again.
