St Clement's Hospital

from the Wikipedia page

St Clements Hospital was a mental health hospital located between Mile End and Bow, in the East End of London.

The building opened in a former workhouse building as the City of London Union Infirmary in 1874. The palatial design of the workhouse had been created by architect Richard Tress and had cost over £55,000 to construct, boasted central heating, a dining-hall measuring 100 feet by 50 feet, Siberian marble pillars, and a chapel with stained glass windows and a new organ. It closed in 1909 but re-opened as a hospital for chronically ill people becoming known as the City of London Institution in 1912 and as the Bow Institution in 1913. It became a psychiatric unit, known as St Clement's Hospital, in 1936 and joined the National Health Service in 1948. It came under the same management as the London Hospital in 1968. After services were transferred to a new Adult Mental Health Facility at Mile End Hospital, the hospital closed in February 2006.

Following the hospital closure the site was transferred to English Partnerships, then to the Homes and Communities Agency, and eventually the Greater London Authority, who marketed it as a regeneration opportunity in 2011. The Government announced that the site would include London's first Community Land Trust. Mayor of London Boris Johnson broke the ground on the site in March 2014. The house prices will not be based on the open market rate but instead will be linked to the average median salaries in the London Borough of Tower Hamlets. The formula will be reapplied every time a house within the Trust is sold, creating what organisers describe as "truly and permanently affordable housing".
