Advice on how to convert large shed into a garage
I have recently bought a property with a large shed (with electrics) in the back garden and behind it a small area to park a car. It's a fairly basic style shed and I'm unlikely to use it for anything other than storage so I'm running through a few ideas in my head. At the moment these are
1.) Convert the shed into a garage with an up-over door. Combined storage-parking option and keeps the large workshop space.
2.) Shorten the shed by a third to make a smaller shed / cabin and increase the parking area. The shed does get morning light in summer (if I did a cabin) and it keeps the storage and parking separate spaces.
Out of these two options, what is more feasible and cost effective? Also if I resold, which option would be more appealing to buyers do you think?
Lastly, what trade or type of work would this involve? I'm not sure where to start or who to ask for quotes. Any advice is much appreciated!
