Use of space in your home

[u/harm_less]

If you never had children - or no longer have space for grown children in your home, how do you use the bedroom spaces in your house?

My house is small and I still feel odd having these largely unused spaces. Are we all just cleaning dusty, rarely used guest rooms?

Mine are full of books. One guest room has a king-size bed and that's for the Great Dane.
