123 Princes Street, Edinburgh

123 Princes Street in Edinburgh is a late 18th-century building that underwent significant changes in the 19th century. The interior was redesigned by David Bryce in 1850, and the facade was remodelled and raised by W Hamilton Beattie in 1873. The building is four storeys tall with an attic and features three bays, constructed from polished cream sandstone ashlar. A modern shop has been added at the ground level, extending over the basement area.

The facade includes a broad painted projecting five-light window in the two left bays on the first and second floors, supported by Corinthian pilasters and an entablature, with a bracketed cornice that continues across the facade, along with a blocking course and acroteria. The other windows have architraves, and there is a consoled cornice at the first floor. The eaves cornice and blocking course are also present. A central tripartite ashlar wallhead dormer features pilaster mullions and scrolls, an entablature, and a segmental pediment, flanked by segmental-headed timber dormers.

The building has timber sash and case plate glass windows and a mansard roof covered with grey slates, with ashlar coped skews, although the stacks have been removed.

Inside, Bryce's Jacobean ceiling remains visible at the ground floor, although it is enclosed within a later ceiling, and there are cornices on the upper floors.
