Right from the delivery I should have realised there was going to be problems. The frame work fixing were either bent or missing the joints completely, the pack lists were completely soaked and damaged making it very difficult to read what was in each pack the construction detail sheet was also soaked and had to be dried before I could risk using them. When it came to the floor the instructions state to use the 100mm timbers to join the floor sections but there was only two in the initial pack so I had to cut some from my own timber stock. I eventually found them all as I opened other packs, the last two were in the pack with the finishing timbers. The floor and balcony were supposed to be a different thickness so the front frame would lip over to form a seal but as mine were the same thickness I had to make good the fault. When it came to the walls the T/G timbers were poorly cut, they were in places wider than the frame work and the gaps between the T/G were so bad that I was forced to seal all the joints with mastic. The roofing felt was also short by 3meters which again I put right with felt I had used on other jobs. When I contacted sales (several times) The stock answer was ''tell us what is missing and we will replace it in 2 or 3 days'' if I had done this it would have taken weeks to complete. I repeatedly said that I had completed the build but I still got the same stock answer I sent some pictures but they kept asking for more, when I pointed out the floor problems they said they would forward the complaint to that department, that was the last I heard of that. The floor was so flimsy that I have had to lay sheets of ply down, the roof panels are so thin that even though the felt nails were short they have all broken through the roof panels making it very unsightly. I was going to allow a full weekend to complete the build but it took well over a week with some help from a friend.
