50 Great Junction Street, 48, Edinburgh

50 Great Junction Street is a four-storey corner tenement building, designed by Thomson and completed in 1885. It features shops on the ground floor and exhibits Free Renaissance architectural details. The exterior is constructed of cream sandstone, with droved ashlar and polished dressings, while the rear is made of coursed and squared rubble.

The building has a continuous cornice above the ground floor, accentuated by pedimented angle pilasters. There are cill band courses on all floors, an eaves cornice with a blocking course, coped angle dies, and decorative cast-iron brattishing. The first-floor windows are adorned with shouldered architraves and a dentilled cornice, while the second-floor windows have carved lintels and hoodmoulds. The angle pilasters are channelled at the first floor, and the windows feature ashlar mullions.

On the southwest elevation facing Great Junction Street, the building has five bays, including a curved corner bay on the outer left with a doorway in a chamfered corner. Above this corner bay, there are curved bays supported by corbels over what appears to be a carved head of Neptune, with bipartite windows. The four bays to the right include single windows in the centre bays and bipartite windows in the outer bays. There are two truncated wallhead stacks on the right.

The northwest elevation facing Henderson Street has four bays, with a replacement shopfront at the ground floor. It features single windows in the centre bays and a commemorative panel along with the street name at the first floor, with single windows in the outer bays and a wallhead stack in the centre.

The northeast rear elevation has single windows and two rebuilt wallhead stacks. The building has timber sash and case windows, mostly with plate glass glazing, some four-pane windows, and several modern replacements. There are five wallhead stacks, with serrated coping and octagonal cans on the southwest and northwest sides. The interior was not seen in 1993.
