Awful decision to buy a dunster house cabin, nothing but problems ever since! The structural base is perfectly level. We have 25 posts supporting 6x2 timber framework above ground. The cabin is warping and the timber walls are literally seperating, the doors have warped and never close properly from 2 months after construction. Damp has come in through the walls, after painting and sealing it... with the product recommended by dunster. Customer support non existent, surely with so many people experiencing the same problem, there must be a law suit against them somewhere?!
