Ok - I eventually got to see one of these lawnmower sheds as follows
Total nightmare
Asgard Metal Sheds is an online only company they are a manufacturer open 5 days a week, so when I turned up on Sat I found it all locked up!! Glimpsing through the gates to see the sheds!!
Back on the Monday though and had a good look around the factory and the sheds. The girl took me around all the stuff they make and all the sheds they do, it was nice to see a British manufacturer actually still in Business!
I ended up buying one there and then! Best thing I have ever seen (not that I知 a shed expert!). I won稚 plug the company too much! But compared to the pap you get from Wickes and B + Q these are amazing. Galvanised, vented condensation proof design, 5 point locking system and a fully integral metal floor/base. Definitely worth a look. I will post a pic when mine arrives (I have to wait for the builder to put a concrete base down to stick it on 1st)
Not a cheap shed though!
