Office Building at Pitstone Cement Works

The office building at Pitstone Cement Works was constructed in 1937 by contractor Peter Lind for F.L. Smidth. It features a reinforced concrete frame with coarse pebble aggregate, which is now painted white, and has a flat asphalt concrete roof. The building has a rectangular plan with a central entrance hall that contains a staircase, and there are axial corridors on each floor leading to the offices. It is designed in the International Modern style.

The building is two storeys tall with a basement and consists of a six-bay concrete frame. The projecting piers support the floors and flat roof, with the first floor and roof extending out as deeply projecting canopies around the entire structure, except at the back (west) where there is a large full-height wall of glass bricks in the central bay that lights the hall. The ground floor also projects over the low basement windows, but not as much. The spaces between the piers are filled with large metal-frame windows. The entrance, which is set back in the central bay on the east front, is accessed by a later flight of stairs, and there are additional later stairs at the south end.

Inside, the large two-storey central hall features a striking concrete staircase with sinuous curved solid balustrades and tubular handrails that spiral around cylindrical newels. The staircase ascends from the basement to a landing balcony overlooking the hall. The glass brick wall that illuminates the hall is said to have the original cacti growing in front of it. The internal partitions consist of glazed metal frames.
