This is believe it or not a " portable airship hangar " . This one to be seen today amongst the building of Farnborough Airport has been given grade 11 listed status for it's role in the past. It was erected around 1910/11 and used in WW1 to house airships or ballons and given the building numbers R51 and Q65 . It is called a portable hangar although to me it looks fairly well fixed.
