Completely rebuilt door as gaps to big to fill also twisted. Completely built new roof as one provided so flimsy it sagged and also bought a roll of better quality felt as the felt provided split as you unrolled it. Removed some of the slats and refitted them as two panels had gaps in them letting the elements in. I then finished by putting 18mm osb board on the floor to strengthen it and cover the gaps between the boards. Overall this company should be ashamed of their total lack of quality in their products as they are certainly not value for money or even fit for purpose.
