Fashioned to fit in with their surroundings, these semi-secret storage system designs turn (un)usually leftover spaces into high-functioning, purpose-targeted places for whatever stuff you might want to stash – including, perhaps, a whole hidden office area.

British bespoke furniture designers at Deriba specializes in custom built-in solutions for awkward (often angled) spaces, including fitted wardrobes and wall units but also sub-staircase storage. The results go a few significant steps beyond bare, wide-open, one-size-fits-all storage.

Flush and smooth with simple hardware (flat round pulls, for instance), what slides out from these odd wall spaces ranges from basic cupboards, cabinets and drawers to clothes-oriented vertical mini-closets fit with hooks and rails.
