                Brick with coped gables to asymmetrically pitched 
                roofs to 4 linked parallel ranges, the north facing steeper 
                pitches fully glazed. Later single storey lean-to cover lower 
                parts of side walls. Front elevation (north) of 5 bays, with

                Part of the lamp charging equipment has been 
                retained in the altered interior. The building is of special 
                interest as a large scale lamphouse built to serve a colliery 
                workforce of almost 4000 men. The Chatterley Whitfield Colliery 
                was in the forefront of mine electrification in the early 
                decades of the C20, and was the first colliery to produce in 
                excess of a million tons of coal per annum, in 1937.
