Houses are individuals. They have to fit our lives and often this means that they are extended and changes are made to layout. This can leave awkward corners. This one is a classic.
Boxed in to hide a soil pipe, next to a dormer, with a sloping ceiling. What a wasted space!
And the solution can be as individual as the problem.
The cupboards could be open, have a hanging rail, shelved, or fitted to fit a particular piece of large sports equipment. In this case drawers were added for clothing storage. Job done!
