Bought a 16x6 Powershed last year to go down the side of the house. Needed more storage (no garage) so have just added a 12x6 shed to go alongside.  Powersheds, do what it says on the tin. Delivered on-time. Quality is good. Yes you can spend a lot more, but  is it really worth it for a shed?  Obviously I am a happy customer and can finally get my bike out of the office and into the shed!
