Cramped flatshares mean many city dwellers are forced into locking non-vital possessions away in storage while dreaming of one day having a house of their own. Storemates is a far more pleasant alternative to the depressing facilities found on edge-of-town industrial estates, where tinned music echoes eerily down fluorescent-lit corridors. The website brings together people looking for storage space with locals who have extra space to offer. You can pay your host a nominal rental fee for the temporary use of an attic or spare room, or pay in kind by weeding their flowerbeds or painting a bookcase.
