Development update

We are pleased to announce that we have been granted planning consent for our new 72,000 sq ft store in Camberwell, London.

We are also pleased to announce the acquisition of a site in Uxbridge for a new 55,000 sq ft store, subject to planning. Uxbridge is an affluent suburb in West London, with a relatively limited supply of self storage, and a catchment area which Big Yellow does not currently service.
