The 2013 competition will give entrants the opportunity to select their own forgotten space, or consider 5 specific sites put forward by London Borough planning departments that have been earmarked for redevelopment.

The competition asks: How would you bring the area under a flyover to life? How could a disused car park be made beautiful? What potential lies in neglected parks, spaces under railways or on our rooftops?

Open to RIBA, RTPI and Landscape Institute members, as well as students, artists, members of the public and community groups across the UK.

1st prize = £5,000, 2nd prize = £2,000, 3rd prize = £1,000
 

Check out the RIBA London website for the full competition brief and instructions how to enter.
