When you live in a small space, you're always looking for new hidey holes within which to store things in. There are always some pieces of furniture and parts of buildings that can be made to work so much harder once someone puts their mind to it.
The staircase in our house has had many reincarnations. It was originally a lowly broom cupboard, but we opened it out to create a mix of hidden storage in the form of deep cupboards and drawers and open shelving for the TV and books. It then became the focal point of our lounge.
I took down the ceiling in part of our home to reveal the loft space above and this area has become a book shelf and perch for storage baskets and the kids' artworks.
Think creatively about how you could put your redundant spaces to work.
