The awning, whilst giving me rain cover in the workshop also gives the family and I somewhere to sit outdoors. The hedge and corner situation of the workshop also act as a wind-break. Those living in the UK are all too familiar with cold breezes pinching the skin of a summers evening ;)
The entire job cost around £250 including extra tough paint for the frames.
So's to make the drain accessible while creating a usable space I put a removable floor panel / splash stopper. Garden tools are stored here in the narrow cupboard enclosed by a 3rd door on the left hand side.
Having made entirely sure that all is weatherproof I have since installed outdoor sockets and lighting in there as well.
