Detached three-bay two-storey university building with attic, built around 1911. The building is constructed of machine-cut red brick laid in Flemish bond with red sandstone dressings, and is irregularly planned, facing east at the north entrance to Magee Campus where Rock Road and Northland Road meet.

The building is roofed with natural slate and features hipped roofs to both front and rear, with roll-moulded terracotta ridge tiles and lead valleys. Four tall corbelled red brick chimney stacks with terracotta pots rise from the building. Paired 2/1 sliding sash windows are housed within timber-framed hipped dormer windows with lead-lined cheeks. Moulded replacement steel guttering is supported on a projecting red sandstone eaves course with two angled cogging brick courses below, and replacement steel downpipes are fitted.

The building has a projecting plinth course and features a red sandstone platband and angled cogging brick course between floors. Windows are square-headed with flush red sandstone basket-arched lintels and red sandstone sills. Most windows are original 2/1 timber sash windows with ogee horns and historic glass.

The east front elevation is three bays wide. To the left is a full-height three-sided canted bay window, to the right a full-height rectangular-plan bay window, and to the centre a single recessed bay abutted by a lean-to entrance porch. Both bay windows feature decorative wall-head dormer windows breaking through the eaves with decorative curvilinear gablets surmounted by ball finials. The recessed entrance bay contains an original tripartite timber casement window. The entrance porch has a single window and a square-headed door opening with replacement timber panelled and glazed door, opening onto a concrete paved platform with five steps and a universal access ramp to the left with steel balustrade.

The south elevation is two bays wide with a full-height three-sided canted bay window to the left. Rising to the right of this elevation is a tall chimney stack with a corbelled vertical projection in angled brick.

The west rear elevation features a full-height projection to the left, a three-storey stair tower to the centre (the upper portion extended from an earlier lean-to at eaves height), and an external steel fire escape. A lean-to single-storey extension with glazed entrance bay to the south abuts the right-hand side of this elevation.

The north elevation fronting Rock Road has randomly-placed windows with a dormer window to the right and a central Dutch-style wall-head dormer window. A tall red brick chimney stack rises from the left of this elevation, similarly detailed with a corbelled vertical projection in angled brick. A coat of arms plaque and chrome-plated lettering reading "UNIVERSITY OF ULSTER" are surface-mounted to the right-hand side.

The building is located on a corner site between Rock Road and Northland Road at the north entrance to Magee University Campus. The front elevation opens onto College Avenue, which leads to the main campus building. A small yard to the rear is enclosed by tall red brick walls with a curved portion at change in height, moulded terracotta coping, and a small red brick shed. The rear of the site is enclosed by a rubble schist stone wall with concrete coping.
