Sorry, I can only give this product 2 stars because of the poor tolerances.

It seems like a never rot plastic shed, which is very worthwhile in London, but it is so hard to assemble especially the roof.
It is impossible to assemble the roof step by step according to the instructions because the tolerances are very big. We put all roof items together and then put the screws so that we can assemble the roof, it's not easy.
In the end, we would like to assemble the door, unfortunately, the holes of the door hinges are too small that the screws cannot fit in.
We 2 people spent 6 hours assembling it without the doors.  
I need to find a solution for putting the doors on. 

You can still buy it if you have a very good tool and a bunch of patience.
