XL Workshop - Good quality but think before you assemble.
This is a robust building which can be assembled fairly easily in 5-6 hours by two able-bodied people. That doesn't mean two muscle-bound blokes, but you do need four pairs of hands to hold and connect panels. The quality is good on the whole, but make sure that you are there when the panels are off-loaded - the driver needs help to get the panels off the truck and it gives you the chance to make sure there are no bits of slight damage during the process. As the workshop is two panels long, replacing the linking nails/coach bolts with nuts and bolts allows you to pull the panels into shape on the base and adds structural strength. I did the same with joining the four roof sections and it paid dividends. So before you start assembling, read the instructions, check that you recognise each part and have a good think first. Otherwise, it's a breeze!
