Trinity House, 1-7 Trinity Quay, Aberdeen

Trinity House is a substantial late 19th-century warehouse located at 1-7 Trinity Quay in Aberdeen. This four-storey building with an attic features nine bays and includes shops and offices on the ground floor, positioned prominently overlooking the harbour. The principal southeast elevation is constructed of grey granite ashlar and is nearly symmetrical, while the sides and rear are finished in coursed granite.

The ground floor, second floor, and central bay have segmental-arched openings, with full-height pilasters on either side and dividing band courses at the second and third storeys. The attic is distinguished by a pair of pedimented wallhead gables, each containing a pair of round-arched windows set into the gableheads. The far left corner bay is rounded and returns to the southwest elevation, which consists of three gables with irregular openings and connects to a two-storey building on the far left.

The symmetrical northwest (rear) elevation has seven bays, featuring a gabled five-storey central bay, although the ground floor openings have been blocked. The building predominantly has four-pane sash and case windows, with curved glazing in the corner bay. There are also a pair of piended roof dormers situated between the attic gables, along with additional dormers at the rear. The roof is multi-pitched and covered with grey slate, featuring beaked skewputts and corniced gablehead stacks with moulded octagonal cans, as well as cast-iron rainwater goods.
