22 Walker Street, Edinburgh

26 Walker Street in Edinburgh is a significant building designed by Robert Brown between 1827 and 1845. This 12-bay terrace features a cohesive façade with a two-storey basement and attic, consisting of three-bay classical townhouses that have main doors and common stair flats at the back. Notable is the later addition of an ashlar attic storey to numbers 24, 26, and 28. The basement area includes some vaulted cellars and retaining walls.

The building is constructed from sandstone ashlar, with droved ashlar used for the basement and channelled ashlar on the ground floor. The entrance platts extend over the basement, and there are band courses at the ground, first, and second floors, along with a string course on the first floor between the windows. The eaves are corniced, and there is a balustraded parapet at number 22. The doors are timber with four panels, set in square-headed doorpieces, and feature rectangular fanlights. Number 22 has rectangular dormers, and there are cast-iron balconies supported by foliate brackets at the first-floor windows.

The rear elevation is four-storey and constructed from regularly coursed rubble with some long and short ashlar quoins. It has an advanced and recessed wall plane with some later additions, and features ashlar rybats, lintels, and sills that accommodate irregular fenestration, some of which have relieving arches.

The windows are predominantly timber sash and case, with plate glass, and include some 12-pane and 6-over-9-pane styles. The roof is a double pitch M-section covered in grey slates, with corniced ashlar gable end stacks topped with modern clay cans. There are cast-iron railings above the ashlar coping stone edging the basement recess to the street, featuring spear-headed finials, along with cast-iron rainwater goods.
