St Line House

St Line House is a five-storey building with an attic and basement, designed in a free Renaissance style with Dutch influences. The ground and first floors are constructed from rusticated bathstone set on a grey stone plinth, while the upper floors feature red brick with bathstone dressings. The building has a parapet with a central attic window that is round and set under a curved pediment, flanked by ball finials. Small segmental-headed aedicules are present on the parapet.

The fourth floor is distinguished by squat Doric pilasters, with round-headed windows that have radial keystones and banding. A dentil cornice runs along the top. The second and third floors are marked by giant Corinthian pilasters, which are fluted and cabled in the lowest zone. The central bay, where the cornice breaks forward, features engaged columns with floral decoration in the lowest zone. The central window on the third floor is round-headed with radial keystones, while the other third floor windows are topped with scrolled pediments.

Banded pilasters define the ground and first floors. The first floor includes a central segmental-headed window, flanked by windows that have engaged Doric quarter columns in their reveals. Below these windows is a band of low relief panels depicting dragons and sailing ships, with the central panel featuring putti holding an inscription. The central entrance doorway is round-headed with radial keystones and is flanked by paired Corinthian columns on high plinths. The ground floor windows are round-headed and have shallow curvilinear aprons.
