When I bought my new apartment there was a conveniently placed laundry space, which seamed perfectly made out to fit a washer and a dryer side-by-side. Until the builder doing the renewal told me it wasn't wide enough. The architect, probably a sadist, made that space 115cm wide.
Long story short, did you know you can shave 5 centimetres from an exterior, although non-load-bearing, wall?
