I do not think Nissen Huts were comfortable in any conditions.
As to Vengeances, I guess they were put together at RAF Drigh Road. There were Maintenance Units there, and a large storage area in an airship hangar, approximately where is PAF Museum now. During the RPAF period there were two Maintenance Units operating, No 101 & 102, responsible for overhauling engines and airframes.
Re Lawrence, I think he was photographed in one of those buildings.
