Reminds me of a flat I once viewed.
There was a pole set up in the middle of the living room. All the sofas were angled so they were looking at it.
The estate agent couldn't tell me whether it was holding up the ceiling or a business opportunity.
I didn't offer on the flat mainly because I was concerned that the pole might have caused structural damage.
They obviously have to be securely fixed in place & it could've caused unseen problems to both floor & ceiling.
(If anyone does have a pole set-up then does it cause problems to rafters or floor boards when you take it down?)
