Flats 1- 4, 1 Bath Street and Flats 1- 3, 20 Bath Street Lane, Edinburgh

Flats 1-4 at 1 Bath Street and Flats 1-3 at 20 Bath Street Lane in Edinburgh is an early 19th century former hotel that has been converted into flats around 2003. This L-plan building, located on the corner of Bath Street and Bath Street Lane, features two storeys with an attic and originally had four bays, with a later bay added to the right that is slightly set back. The exterior is classically detailed, constructed of painted polished ashlar with a channelled ground level on all bays except the outer right, which is rendered. The side elevation and rear elevation are harled in lined render with droved ashlar quoins. Architectural details include a base course, a band course between the ground and first floor, a cill course at the first floor, a mutuled cornice, and a blocking course. The first-floor windows are architraved, except for the outer right window.

On the northwest elevation, there are four steps leading to each deep-set, panelled door located in the first and fourth bays. The outer left features broad, curved ashlar ingoes, an architraved and corniced doorpiece, and a panelled frieze. At the wallhead of the two bays on the outer left, there is a curvilinear gable with a bipartite window and a moulded cill course. Above the door in the fourth bay, there is a plate glass rectangular fanlight and window. The entrance is enhanced by a Doric columned porch with a mutuled cornice, and Doric pilasters are present between each bay at the first floor.

The windows are timber sash and case with plate glass. The roof is a grey slate mansard with pedimented dormer windows in the three outer right bays of the northwest elevation, while the central dormer window is bipartite. The building features ashlar coped chimney stacks on the right side elevation and between the third and fourth bays, a gablehead stack between the first and second bays, a droved ashlar shouldered wallhead stack, and a harled, coped and shouldered wallhead stack on the northeast side elevation, along with a cream brick chimney stack at the rear. The interior was not seen in 1994.
