There was a thread on here a few days ago where the poster was looking to combine a loo and utility - there were a few alot of posters which hated the idea of clean laundry need a loo, and others that suggested it would be OK if walls were put in.
This is similar - idea would be that a cupboard could hide the WM/TD and it wouldn't really be used for drying wet laundry. Intending that when we have guests who need to use the loo, it would just look like a corridor because floor to ceiling doors would close all the utility bit off.
We do have a utility at the moment, but extension means we have to change it and just considering options.
