I would be interested to hear what do you prefer WIR or BIR and why.
To be honest looking at some plans it looks like BIR would be a better option as some WIR take so much space.
I get the idea if you had lots and lots of clothes and shoes it would be fab to have a huge fancy WIR with a sofa, mirrors, etc... however for your everyday joe and jane, do you really need a WIR?
