How do you fancy living on the water within the Olympic Park or in a home built on a low-level bridge in east London?

Well you may be able to if any of the 100 shortlisted ideas presented as solutions to the housing crisis are successful.

New London Architecture, the capital’s development think-tank, will bring together the proposals during a two-week free public exhibition at the NLA galleries in The Building Centre.

Then 10 winning ideas will be selected by a team of housing experts, with winning submitters invited to join a Greater London Authority working group to examine how their ideas can be applied to real London sites to deliver future housing for the capital.

Among the submissions from world-renowned architects are a new mega-city near the M25, transforming London’s docks into water neighbourhoods (called Floatopolis), re-purposing rooftops and the creation of 50,000 new homes on low-level bridges across east London.

Alastair Parvin and Adam Towle in partnership with the WikiHouse Foundation proposed an initiative called Right To Replace in which homeowners could demolish their properties in the suburbs to build a new home – but only if it occupies half the space.

London Housing Commission chair Lord Bob Kerslake said: “The scale of the challenge is so big that we genuinely need some fresh thinking.

“There are a lot of new ideas here particularly new approaches to tenure and off-site construction.”

The ideas will be displayed between Thursday, October 15 and Thursday, December 17, accompanied by a programme of events to establish how London’s housing needs can be met.
