RAF Wittering: Electrical testing building A08

The electrical testing building A08 at RAF Wittering is a 20th-century structure made of reinforced concrete and brick, topped with an earth mound roof. It has a U-shaped plan with the base facing east and the uprights extending west from each end, creating a nearly symmetrical internal layout.

The building features a single elevation on the east side, which is one storey high and ends with projecting sloping screen walls that support the earth mound. Originally, there were six doors on this elevation: the outer two were double timber doors serving as entry and exit points, located beneath louvered vents, while the two inner single timber doors led into the plant room. Between each doorway were two two-light steel casement windows, but the southern center door has been blocked with brick, as have all the windows. Above the low concrete parapet, there are two extractor fan outlets, symmetrically placed, with the southern outlet still retaining its louvers.

Inside, the west end of each upright of the U contains the reception, packing, and assembly departments, with the testing and dressing sections to the east. A north-south corridor runs the length of the building, with double doors at intervals. At the front, the instrument servicing and standards departments each have two east-facing windows between the double doors, and these facilities are mirrored on the north and south sides. East of the long corridor, illuminated by the remaining east windows, are the records office to the south and a storeroom to the north, separated by an unlit plant room. The internal walls are constructed of stretcher bond brick, and each area is equipped with high-level ventilation grilles. The front windows are intact and protected by internal steel security grilles.
