9 Walker Street, Edinburgh

7 Walker Street in Edinburgh is a Grade A listed building designed by Robert Brown between 1822 and 1824. This structure features a 12-bay terrace with a unified façade that includes two-storey attics and basements, as well as three-bay classical townhouses with main doors and common stair flats located behind. There are later additions in ashlar at the attic level and a three-bay return to William Street. The basement area includes some vaulted cellars and retaining walls, with sandstone ashlar that is droved at the basement and channelled at the raised ground floor. The entrance platts oversail the basements, and there is a banded base course along the bottom. A banded cill course is present at the first floor, along with a string course between the windows. The building features a corniced eaves course and is balustraded with rectangular dormers on the right side. The main entrance includes timber six-panel doors with a rectangular fanlight above, while No. 9 has geometric glazing. The centre window at the first floor of the northern corner block is architraved, corniced, and bracketed. Additionally, there are cast-iron balconies on scrolled brackets at the first-floor windows.

The north elevation facing William Street has three storeys and is constructed of regularly coursed rubble with long and short ashlar quoins, featuring stone cills and lintels. There is a window in the centre at the ground, first, and second floors. The west (rear) elevation is four storeys high and also made of regularly coursed rubble with some long and short ashlar quoins. This elevation has an advanced and recessed wall plane with some later additions, and it includes ashlar rybats, lintels, and sills to the irregular fenestration.

The windows are predominantly plate glass in timber sash and case, with some featuring 12-pane and 6-over-9-pane designs. There are cast-iron railings above the ashlar coping stone edging the basement recess to the street, topped with spear-headed finials. The roof is a double pitch M-section style, with wallhead stacks in corniced ashlar and modern clay cans. The building also has cast-iron rainwater goods.
