31, 33 Marshall Street, Edinburgh

31 and 33 Marshall Street in Edinburgh is a mid-18th century building with a Scots baronial section added in 1877. It is a four-storey and attic L-plan tenement featuring commercial premises at the ground level and a basement at the rear. The earlier section has a two-bay gable elevation facing east and a three-bay double-gable elevation to the south, with a narrow canted bay in the re-entrant angle. The original part is constructed of random rubble with dressed margins, while the later section from 1877 is made of squared and coursed rubble with ashlar margins and is painted at the ground level. Some windows have raised architraves, cornices, and strapwork pediments, while others feature consoled cornices at the ground level. The dormers are piended and finialled with pediments, some displaying the monogram DC, and one dated 1877 on the south side.

The eastern shop front is pilastered with a timber fascia, and there is an advanced pedimented doorway to the south with recessed panelled timber and glass entrance doors. The earlier section predominantly features 12-pane timber sash and case windows, while the later section has 2 over 4 pane timber sash and case windows. The shops have plate glass windows, and the roof is covered with grey slates. Gable stacks and raised skews with scroll skew-putts are also present.

The interior was partly seen in 2007, and the shops have been comprehensively modernised.
