I have written on this subject before, but there is still a WW1 Aeroplane maintenance shed at Moreton Village in Essex, that was originally sited on North Weald airfield while home to the famous Zeppelin killing RFC 39 night fighter squadron.
The surviving structure is one half of a double apex shed. It left the airfield in the 1930’s when the site was significantly re-developed into what was eventually the grass airfield and buildings of WW2.
The hangar was used as the village service station, and car maintenance workshop, and laterly as a car spray shop until the 1980’s. It has been empty for some 15 years, and the site upon which it stands is now up for sale/redevelopment.
Just to update ,the site at Moreton is now under offer.
