NHER 65662 (Building record) - Late 19th-century engine house at Trowse Sewage Pumping Station

December 2021. Listed, Grade II.
This three-storey red brick engine house was constructed at Trowse Sewage Pumping Station (NHER 26403) around 1869 to house a steam-powered engine. It may have been built to designs prepared by Alfred Morant, city engineer to the Norwich Corporation. Rectangular in plan, the exterior features dressing of yellow and blue engineering brick and a slate roof. The entrance is located on the south, where a dog-leg staircase leads to a double doorway on the first floor. To the right of the staircase there is a tall carriage arch with double doors. An adjoining ancilliary range composed of a contemporary boiler house, workshop, smithy, and coal store is considered separately and is not Listed.
The sewage works was upgraded in 1909, with the construction of a new engine house, boiler house, and coal store immediately to the southwest (see NHER 65663), and this engine house was de-commissioned.
Documentary research indicates that all of the original machinery has been stripped from the building except for an air receiver tank located under the main staircase.
