My shed has been up a couple of months now. The quality is very poor. So many of the tongue and groove slats do not fit correctly, some panels split, loads of holes and large gaps around the doors and windows. I took a long time to fill and sand the holes and gaps, but now with the warm weather, all panels have expanded and now have over metre long gaps where the tongue and groove was never fitted correctly. So the shed is far from water-tight. Also all the panels are roughly cut and not square. A professional joiner had to try to pull them all back into position and built the shed using ratchet straps and supports or it would have been impossible. So many panels needed to be trimmed or even reconstructed. The screws supplied for the roof supports were not strong enough and it started to sag and needed to be supported with additional bolts. The floor, coming in six sections is a joke. Massively off-square and very flimsy and bouncy. I had to invest in a chipboard floor to go over the top. One of the plastic windows was supplied with a small crack, I couldn't be bothered making a fuss about it, but after a couple of weeks it completely shattered from what I assume was a bird strike. All in all, a very shoddy and cheaply made product with cheap wood and ill-fitting parts. And this is meant to 'premium' product ! BTW, this is what £2,500 gets you !! I wish I had read the review sites as Waltons get appalling write ups. Go elsewhere as this company is awful.
