I really like the solution that KHBT architects have come up with for this flat in Mayfair.  As you can see from the plans below, the space dealt with some inconsistent floor levels which they worked around by crafting a gorgeous, precise stair case and hallway that links the main space with the bathroom.  It’s quite a stark finish (clinical, even?) but the quality of the work gives a sleek, expensive look.

I also like the storage wall in the bedroom which also cleverly disguises access to the flat’s entrance.  What do YOU think of this flat?
