Stackable football pitches could be erected on disused or temporarily empty plots across London, according to Amanda Levete and her London-based studio AL_A.
The concept, named Pitch/Pitch, aims to tackle the shortage of inner-city sports fields available in the centre of the UK capital.
Designed by AL_A with Arup engineers, the modular system would comprise a lightweight carbon-fibre structure, able to stack five-a-side football pitches one on top of the other.
The towers are designed to be quick and easy to install, allowing them to be erected temporarily for events such as World Cup tournaments.

"We've designed this intervention to encourage the theatre of the game, with spectators and would-be players drawn in as Pitch/Pitch animates the cityscape," said AL_A director Maximiliano Arrocet. "Pitch/Pitch allows the game to retain an urban flavour, adapting to the number of players and awkward shaped sites."
The towers are intended to have a lifespan ranging from just a few days to a year, meaning they could be used to fill sites awaiting development. One such proposed site is the car park of a wine merchant in Shoreditch, east London.
But AL_A is currently in discussions to consider how the scheme might be funded and implemented across the city.
This wouldn't be the first time the studio has worked with carbon fibre ? the architects used the material, more commonly associated with the marine and furniture industries, to create a canopy of transluce...
