UK consulting engineer Arup and London-based architect AL_A have designed Pitch/Pitch, a modular system that allows carbon fibre football pitches to be easily stored and erected on derelict or temporarily vacant sites.
AL_A says the idea is to allow the game to retain an "urban flavour", adapting to the number of players, from three-a-side upwards, on awkwardly shaped sites.
The space could also host other activities such as fitness classes for children and adults during the day.
The pitch could last for a fortnight to coincide with a World Cup tournament or last for a year while a site lies dormant.
AL_AÂ notes that "London suffers from a chronic lack of space for sport. Children no longer play in the streets as they once did and adults who want an informal game after work are frustrated by a lack of spaces and by high costs for what is available."
The firm says it is "working with partners with a view to financing and implementing the scheme across London".
