Flour Mill, Carpet Lane, Leith, Edinburgh

The Flour Mill on Carpet Lane in Leith, Edinburgh, is an impressive six-storey warehouse built in 1828, featuring classical architectural details. The building is primarily constructed of cream sandstone with an ashlar west front, droved ashlar on the ground floor of the south and southwest elevations, and coursed and squared rubble above, with coursed rubble at the rear.

The west elevation, facing the shore, has four bays. The outer left bay is plain with single windows, while the three bays to the right have a raised ground floor divided by shallow strip pilasters. There is a door to the right supported by a scrolled bracket, with a cornice above. The tall first floor features Ionic columns and a deep cornice, with single windows above and arcaded windows on the third floor.

The southeast elevation, facing Chapel Lane, has five bays. The bay to the right of centre has a taller opening that breaks the band course, which is now blocked, with single windows above. The centre and outer right bays feature broader openings (pends), and there are bipartite windows on the first and second floors of the centre bays, with single windows in the remaining bays.

The southwest elevation, facing Broad Wynd, has ten bays. The four gabled bays to the right have single windows and a bull's-eye window in the gablehead. The six bays to the left include loading doors in the second and sixth bays, which were formerly covered with wooden lucams, while the remaining bays have single windows set in three-storey giant arcades. The south jamb has a recessed bay with altered openings and a corniced and bracketed door surround at the second-floor level, with a round-arched opening above. The return elevation of the south jamb is blank but shows remains of fireplaces. There is a two-bay Broad Wynd elevation of the south jamb featuring a multi-pane glazed shop front (No. 7 Broad Wynd) with single windows above.

The north (rear) elevation mostly has single windows and altered openings, with two-storey giant arcades on the northeast elevation. There is a small square-plan addition at the re-entrant angle.

Inside, the ground floor features slender cast-iron columns, while the floors above are constructed with timber beams and posts. Some ten horizontal-pane timber casement windows remain, along with internal wooden shutters, and the building is topped with a pantile roof.
