A single-story brick utility building in the British wartime style, with red brickwork, pale stone lintels over the windows, and a low-pitched corrugated roof. A tall brick chimney rises at one gable, and rain downpipes run down the corners onto a raised concrete plinth base.

Two plank doors and small barred windows front the block, suggesting separate service rooms of the sort used for civil-defense and decontamination facilities during the war.

An excellent support structure for a 1940s home-front or airfield diorama, a wartime village on a model railroad, or a wargaming board that needs a compact, defensible brick outbuilding.
