The practice, which operates from Goldsmiths at the University of London and was founded by British-Israeli architect Eyal Weizman, had been shortlisted for its investigative work into incidents including alleged race-motivated murder.
It is currently building a three-dimensional model of how fire spread through Grenfell Tower.
Forensic Architecture’s work will be displayed at Tate Britain until January 2019. The practice received £5,000 for being shortlisted.
The £25,000 first prize was won by Prodger for her solo exhibition BRIDGIT / Stoneymollen Trail at Bergen Kunsthall.
According to the jury, Prodger’s work, shot on a smartphone, ’interweaved bodies, thoughts and landscape’ in her work. The judges said they admired the painterly quality of BRIDGIT and the attention it pays to art history.
The other finalists were Naeem Mohaiemen and Luke Willis Thompson.
Forensic Architecture was chosen for the shortlist for its work at the documenta 14 art show and for its own exhibitions, including Counter Investigations: Forensic Architecture at the Institute of Contemporary Arts in London.
This presented a selection of the practice’s recent investigations, including one into the death of a man in Kassel, Germany, and of migrants in the Mediterranean Sea.
The jury praised Forensic Architecture for developing ‘highly innovative methods for sourcing and visualising evidence relating to human rights abuses around the world, used in courts of law as well as exhibitions of art and architecture’, Tate Britain said.
It was the second time an architectural practice has been nominated for the £40,000 art prize. In 2015 East London architecture outfit Assemble, at the time an 18-strong collective, became the first architecture practice to win the accolade.
