The building was subject to assessment in 2000 (SUP 4) and a programme of historic building recording was undertaken in 2011, prior to demolition.

This building is a single-storey rectangular structure of red brick laid in Flemish bond and a pitched asbestos slate roof, with a flat, felted roofed extension to the rear joining it to the boundary wall with Butt Road. This extension is a later addition as is shown by the 1875 and 1897 O.S. maps which depict the structure as freestanding. The building originally functioned as the Ablution House in conjunction with the Soldiers’ Latrine located to the north-east which was destroyed when Circular Road West was constructed in the late 1970s. The south-east elevation has a range of five windows, three of which are original, displaying the characteristic window heads of alternating red and yellow brick voussoirs. A later Crittall metal-framed window has been inserted into one of the original openings and is slightly wider than the arch of the window head. The remaining window of this elevation is a large dormer with an unhorned sash window of eight over eight lights. This has replaced the original entrance to the building. The ridgeline of this dormer has a crest of upright geometric tiles.<1>

The north-west elevation, the rear of the building, has four original windows in line with those on the front elevation. A probable fifth window, in line with the original entrance, has been removed by the construction of the extension. However, a window looking out onto Butt Road does exist where this extension is tied into the boundary wall. This has been bricked in at a later date.

The south-west elevation shows a centrally-located entrance inserted into the short end of the original structure. This has two small lights above it and is surmounted by a deep cast concrete lintel. Directly above this lintel is an original small, square-shaped louvred window with a York stone sill and the characteristic window head. Immediately to the rear of the main structure is the later extension. The south-west elevation has a narrow Crittall window of three lights and two single door entrances surmounted by a wide concrete lintel, opening into two separate rooms. These flat-roofed rooms are of differing height, with the one tied into the boundary wall being built higher than the wall itself. It is probable that this increased height housed a water tank to provide pressure, although there is no direct evidence of this. The lower of the two flat roofs has a later brick alteration raising the overall height but keeping it below the level of the other roof.

The north-west elevation displays the same inserted entrance and original louvred window as the opposite end on the main block, while the façade of the extension has a window near to the eaves of the lower-roofed room. This window is of the same dimensions as the original ones in the main block but has a sill and lintel of cast concrete.

The interior of the former Ablution House has three distinct areas of increasing size. Off the south-western entrance are urinals and two WCs, on either side of a central passage. A door in a brick cross wall provides access to a larger room used as a kitchen, while a further door in a second cross wall provides access to a large square room, latterly used as an office. Both entrances in the cross walls show evidence of originally having been wider and of having a brick arch above. All three rooms have what appears to be the original boarded ceiling and have tiled floors, although the largest of the three rooms has carpeting concealing this. The rear wall of the central room is not original and has been moved further into the main block to accommodate the extension to the rear. The extension comprises a room with a WC and sink, closest to the main block, and a square room, which is empty except for shelving. The height of the extension suggests the former presence of a water tank and these two rooms probably originally held the boiler room and equipment necessary to heat the water for the Ablution House. The tiled floor of the main block is original and reflects the function of the building.
With the proximity of the Latrine to the north-east, it is unlikely that the smallest of the three rooms was ever originally designed as a lavatory. The presence of the louvred windows at either end of the building suggest that these rooms were designed to have a damp atmosphere and that the smallest of the rooms held sinks, whilst the largest was for baths, with the middle room doubling as both entrance and a place to heat water.
