We're in the process of renovating our PPOR, which is a sandstone house built directly on to stone. We have a lot of space under the house (about 2 bedrooms worth), height enough for a 6ft person to be able to almost stand up. I'm looking for suggestions on how to best use this space. Since the access isn't the best, I plan on having a trap door installed in the house. Does anyone have experience with using the space under their house? I'm thinking of using it to brew some beer and store some wine. Maybe a little bar/man cave. Possibly a meditation spot.
