16 Alva Street, Edinburgh

6 Alva Street in Edinburgh is a classical terrace building designed by J Gillespie Graham in 1823 and completed by R Hutchinson between 1826 and 1830. This impressive structure features a 33-bay façade that includes both 2 and 3-storey townhouses, with main-door and common stair flats located behind. The building has a basement area that includes some vaulted cellars and retaining walls. Notable later alterations include a corniced storey added to Nos. 12 and 24.

The exterior is constructed from sandstone ashlar, which is droved at the basement and channelled at the ground floor. The entrance platts extend over the basement, and there is a band course at the ground floor, along with a banded cill course at the first floor. The building has a corniced eaves course and a partially retained balustraded parapet on the left side. The openings at the first floor feature architraved and corniced surrounds, and there are cast-iron anthemion balconies at this level.

The windows are predominantly 15-pane and 12-pane timber sash and case, with some plate glass also in timber sash and case. The roof is a double pitch M-section covered with grey slates, and there are corniced ashlar ridge stacks topped with modern clay cans. The basement recess to the street is edged with ashlar coping stone and has cast-iron railings.

Inside, the interior showcases a Greek decorative scheme characterized by key motif cornicing. The building was converted for office and residential use in 2008.
