After the war, cash shortages lead to the complex not being completed and it was converted to an outdoor swimming pool, opening in June 1946 using wartime gas decontamination rooms as changing facilities.
The rebuilding works were funded by a planning benefit arranged by Stanley Thomas, Chair of Holborn BC Leisure with the Hammersons group.
It included the 10 storey office block, Berkshire House, as a facade and front entrance from High Holborn plus sun bathing terraces built above the indoor pool and the rear underground car park area.
The entrance building on Endell Street was demolished and offices, a new public and establishment laundry plus warm baths and shower facilities, were installed on the ground floor.
Three floors of sheltered housing for elderly people were built above this, and Dudley Court occupied the ground of the demolished Workhouse at the rear.
In the mid 1990s the main sports hall was converted to a multi exercise equipment gym and the sauna was relocated to the previous warm baths and shower area to provide a dance studio.
