If I may briefly hijack this thread – how do you know what’s underneath your ground floor?
I didn’t see our house being built, but I watched the ones across the road going up – although they have a different design. They’ve got two storeys up front and three at the back because the plot slopes a lot. BUT underneath the front they built full sized room and filled it with giant inflatable bags, then built on top of it. It seems absolutely bonkers to me not to have made that into a store room.
Now I woudln’t have thought that they’d build our house like that since it’s the same front and back, but when you stamp on the ground floor there’s definitely some resonance. Tempted to drill a small hole in the floor and lower down a camera!
