Street Shelters

Hello to all,
Does anyone know where I can get the dimensions of street shelters, for instance, 50 people street shelter length, breadth and height.
Thanks

 

There's literally hundreds of files if you do a simple search on the National Archives Catalogue - For example this file at Kingston Archives

 

Thank you Horsapassenger for the link most useful

one I took a photo of in nw London the sizes were my guesstimates but roughly same size as below
Air Raid shelter ,Ruislip,Middlesex


more info below
With its entrances at either end now blocked, it would appear that the shelter had three internal compartments. The overall external dimensions are 36ft (11m) long by 13ft 4in (4m) deep and 7ft 6in (2.3m) high. It would probably have been designed to accommodate thirty six people. Photographed in 2013.

CL1 you are a star, It's just what I am looking for. I want to build a model of the shelter with a couple civilians and an ARP warden in attendance.
Thank you very much.
