These two structures are situated either side of Broomhill Farm's gate and make up what was the pump house for the FBL 'Flame Barrage, Land'
Abit of history :-
By early 1941 a flame barrage technique was developed. Rather than attempting to ignite oil floating on water, nozzles were placed above high-water mark with pumps producing sufficient pressure to spray fuel which produced a roaring wall of flame over, rather than on, the water.Such installations consumed considerable resources and although this weapon was impressive, its network of pipes was vulnerable to pre-landing bombardment; General Brooke did not consider it effective.
Here are the few shots I managed to get of the pump house's.
