Bonar House, 17 Bell Street, Dundee

Bonar House, located at 17 Bell Street in Dundee, is a three-storey and basement educational building designed by Robert Gibson in 1928. It features an H-plan layout and is built in the Edwardian Baroque style on sloping ground. The facade is made of red sandstone ashlar with pink stugged and snecked rubble on other parts, and the roof is concealed.

The front elevation is symmetrical with seven bays. It has a battered base course topped by a band course, a moulded lintel course at the ground floor, and a cill course at the first floor. The corners of the east elevation are accentuated with quoin strips. All elevations have a wallhead course and corniced wallhead, with shallow pedimented parapets on the front pavilions and a stepped parapet at the centre. The windows are border glazed with top-hopper metal frames.

The central entrance features two-leaf doors with fielded panels and a keystoned round-headed fanlight, framed by a pilastered doorpiece with a consoled segmental canopy. To either side of the entrance are two keystoned windows with cavetto reveals. The first and second floors have five windows set in recessed panels, with bays marked by Ionic half columns. The single bay pavilions on the left and right are channelled at the ground floor, each with a round-headed window, while the first-floor windows are pedimented and flanked by two-storey pilasters with mannered Doric capitals.

The east elevation has three bays, with the ground floor concealed by a church. The outer bays are blind, while the centre bay is deeply recessed and features a large stair window with border glazing, leaded panes, and frosted glass.

The south elevation, facing Royal Exchange Lane, is symmetrical with nine bays. It includes three two-leaf panelled doors with corbelled cornices, flanked by single windows. There are nine windows across the principal, first, and second floors, all set in recessed vertical panels, with an additional two-storey single window bay recessed to the right.

Inside, the gymnasium has a large timber doorpiece with paired double doors and a large segmental fanlight. The well stair features steel balusters, and the former Principal's office is oak panelled. Throughout the building, there is a boarded dado that is covered with modern sheet imitation boarding.
