Aside from the people that install palatial gyms, garages and their own yoga rooms; has anyone dug out a basement under their home?
I am only thinking enough space for storage so about 10ft x 10ft. Its a victorian terrace and no other houses on the terrace have one as far as I know so it may not be feasible. I'm just idily wondering if the cost of doing it would be more than £20k if it's just for storage. £20k would buy a lot of off-site storage but that's not remotely convenient for bikes, suitcases etc.
I don't know if the minimum heights have to be complied with if it is not going to be used for anything else (though obviously you'll need to be able to stand up in it). I could speak to a builder but I don't want to be hassled for months.
