1. Baby Cage
We've all tried to maximise space in our increasingly small flats. Whether it's vacuum packing or simply stuffing everything inside a closet that's already housing the boiler, we're always on the look-out for a new form of storage. Back in the 30s, city-dwellers were offered the Baby Cage, a totally safe and responsible contraption which dangled your child storeys above a busy street. Unsurprisingly it was soon replaced by the window garden.
