Do not buy from these Del boys! The quality of wood is very poor and when a problem is highlighted their customer service team reply with 'well it is wood and we cant stop it deforming ' Had the cabin getting on for two years. Within a few months we had a downpour which flooded along the so called sealed wooden beams. The whole cabin now swells and shrinks with the conditions even though it's been treated with over £100 worth of the wood treatment recommended by Dunster. I've recently had to make some metal strengthening bars in work in an attempt to hold the beams together. On really hot days the beams swell so much gaps appear and we can see daylight through them. 10 year guarantee my arse. Be lucky to get another 12 months out of it. Very poor choice on my part.
