Tweeddale House, 9, 11 Tweeddale Court, 14 High Street, Edinburgh

Dated 1576, Tweeddale House is a complex of residential and commercial buildings situated on the south and east sides of Tweeddale Court, with a 16th-century townhouse forming its core. It has undergone remodelling and extensions from the 17th century onwards. The building is constructed of rubble with a mix of chamfered and moulded ashlar dressings.

The principal (south) elevation is a two-storey building with an attic and a lower ground floor, spanning three bays. The facade is painted, featuring a Gibbsian doorpiece with a Roman Doric porch in the centre. Steps at the re-entrant angle provide access to the lower ground floor. To the rear, a three-storey, eight-bay section exhibits regular fenestration.

An extension to the west, encompassing numbers 9 and 11 Fountain Close, is a two-storey and attic structure with four bays. A doorway is located on the ground floor to the right, and a forestair leads through an archway to a first-floor entrance at the western gable end.

A range to the east side of Tweeddale Court, comprising numbers 5 and 7, originally served as industrial buildings and have now been converted into residential units. This range is three-storeys and attic in height, spanning five bays. Number 5 features a shallow segmental-arched recess at the first floor level, housing a cast-iron winch with ornamental ironwork. The east elevation includes a door with a fanlight and unusual ogee-arched, traceried ashlar detail above. To the left is corbelling at the ground floor corner-angle. Decorative wrought-iron entrance gates link number 5 to a fragment of a freestanding wall, which is listed separately.

The windows are 12-pane timber sash and case windows. The roof is covered in Scottish slate. Broad, harled stacks have clay cans, and cast-iron rainwater goods are present.

The 16th-century section of the interior includes a barrel-vaulted entrance hall. A door on the north wall bears the date 1576, along with the initials of Neil Laing and his wife, Elizabeth Danielstoune, and an inscription reading "The Feir Of The Lord Preservith The Lyfe”. Behind this is a large hall with arched buffet recesses. An eastern chamber features an aumbry containing a painted guilloche design. Further interior features include moulded doors and fireplaces. The first floor, formerly the High Dining Room, boasts a plaster ceiling designed by James Nisbet in 1782, complemented by Adam-style timber bookcases added in 1827. Pilastered doorpieces feature block pediments and crenellated parapets, with additional Neo-Classical detail in a room to the east. Sections of a bellcast roof dating back to 1752 are concealed beneath a pitched roof constructed around 1800. The western extension, dating circa 1791, includes two groin-vaulted rooms on the ground floor, featuring a flue and iron safety rails set within the stone-flagged floor. A room on the first floor contains an iron safe embedded within a wall.
