Construction workers building a new type of hut for soldiers, during World War I. This photograph shows builders working on the framework of a new type of hut for resting soldiers behind the frontline. It is likely that these recreation huts were used for soldiers who were on short leave from the fighting. Many of the famous YMCA (Young Men's Christian Association) resting huts were located almost on the front line, and the branchless trees and uneven ground in this image suggests that these huts were also being built fairly close to the front line. It could be that these huts were an early prototype of the Nissen hut, as the British military engineer and architect, Peter Norman Nissen (1871-1930), served in the British army as a lieutenant colonel. Though Nissen huts were traditionally tunnel-shaped sheds of corrugated iron with cement floors, the huts in this image look like they were built with wooden floors.
