Look don’t be mistaken it’s a plastic shed 
But seriously for the price and the fact it will never rot is great 
I put it together on my own 
Took me 4 hrs taking my time on a Sunday 
Best bit of advice is make sure your ground is level that is a must 
The rest will just fall into place  you need a cordless screwdriver and maybe a hand one as well for some of the smaller areas 
Follow the instructions just as it says do not be tempted to put more screws in that it says 
Remember it’s a process and there are reasons for the amount of screws you put in at a time 

All in all was it worth £400 maybe the question is you you build a wooden one for that 
Your paying for the convenience and the fact it’s not going to rot
