18 Rothesay Terrace, Edinburgh

18 Rothesay Terrace in Edinburgh is a terraced townhouse building designed by R H Watherston and A Craig between 1906 and 1907. It features four storeys and a basement, built in a plain classical style with sandstone ashlar. The entrance platts extend over the basements, and there is a banded base course. A moulded band course at the second floor includes a cornice that connects to No. 16, which is listed separately. The building has a corniced eaves course and corniced main doorpieces with moulded architraved surrounds and rectangular fanlights. Above the main entrance, there is a corniced and moulded architraved window at the first floor with a raised apron. To the right, there are corniced two-storey, three-light canted bays, with bipartite windows above the canted bay at the second and third floors.

The windows are made of plate glass in timber sash and case frames, with some larger windows featuring plate glass over two-pane timber casements. The doors are two-leaf timber panel doors. The roof is a double pitch M-section design, with corniced ashlar ridge and gable end stacks topped with modern clay cans. The property has cast-iron railings on ashlar coping stone edging the basement recess that faces the street, along with cast-iron rainwater goods.
