Highcroft Hospital, Main Building

Highcroft Hospital's main building, originally the Aston Union Workhouse, was constructed in 1869 by architect Yeoville Thomason and builders Jeffrey & Pritchard. The building features red brick with blue brick and stone dressings and bands, topped with tiled roofs that have a deep enriched eaves cornice, all in the High Victorian Gothic style.

The structure has a slightly projecting central bay with five windows, flanked by long ranges, and stands three storeys tall. The entrance is marked by a brick and stone banded round-arched design, topped by a Gothic traceried pediment that bears an inscription commemorating its construction. The ground and first floors have four-pane sash windows with patterned cambered arch heads, while the second floor features small-pane sashes with patterned pointed heads. The flanking ranges are styled similarly.

Behind the entrance, there is a rectangular plan tower with arcaded pointed windows and a pyramidal roof, which has tall brick chimney stacks at each angle and is topped with a louvered cupola. Inside, the entrance hall is supported by timber brackets and features a currently clad stained glass ceiling that was originally lit from the tower windows. There are two pointed arch doorways that flank a large pointed arch leading to a stairway towards the rear recreation hall, which has a heavy timber arch-braced open truss roof and a stage.
