A charity that turns empty shops into temporary spaces for community use.
They have doene many things in the North West - Oldham, Salford, Wigan and Manchester.
This included the Circus House in Manchester - http://www.thecircushouse.co.uk/
I think that this idea of pop-up, less precious approach to investing in the community has potential, particularly at the moment. Plus, if it was always going to be temporary, then it can't fail - only suceed while it is there.

Dementia Adventure connects people living with dementia with nature and a sense of adventure.
