Land will be made available across Bristol to test affordable housing options over the next five years, according to the council's cabinet member for housing.
Councillor Paul Smith announced the plan at the official launch of the Bristol Housing Festival at City Hall on 25 October, where he also committed council investment to building modular homes for one of the sites, to accommodate people in housing crisis within six months.
Some of the sites that will be used have been deemed 'undeliverable' when using conventional housing methods, but homes that are manufactured offsite, such as ZEDPods, can be put up quickly, sometimes in as little as a day.
An average two-bedroom house in Bristol cost £222,000 in 2017, compared to £60,000 in 1990; around 500 families with children are staying in temporary accommodation every night.
Smith said: "The council will support the festival in using the city as a laboratory for housing innovation, making available a variety of sites. Some of these will seem 'impossible'; some will be between, on top of or even underneath existing buildings. So, we are inviting ideas from all over the world and saying let's be imaginative, let's challenge, and let’s be prepared, if necessary, to fail and try again."
The free exhibition, which opened on 19 October and runs until 4 November, has already attracted over 2,500 visitors.
Bristol mayor Marvin Rees, who also spoke at the launch, said: "The festival can turn the city in to a living exhibition of the latest and most innovative approaches to housing and finding the best way of tackling our housing crisis.
"It is not just about homes, but about communities too, and solving wide social challenges such as social isolation and mental health issues through housing."
A £175m mixed-use development scheme is planned for the landmark site of the Soapworks in Bristol that will include new homes and an apart-hotel.
