Queensberry House, 64 Canongate, Edinburgh

Queensberry House, located at 64 Canongate in Edinburgh, was built between 1667 and 1670, with later additions and alterations by James Smith. It underwent extensive renovation and was partially incorporated into the Scottish Parliament complex from 1999 to 2004. This substantial mansion is three stories high with an attic and has an F-shaped plan. The exterior is finished in lime-harled rubble with ashlar dressings and features regular fenestration with raised margins.

The principal (north) elevation showcases a rusticated single-storey entrance hall with a blind attic, flanked by full-height, advanced two-bay gabled wings that have wall-head stacks. The entrance features round-arched rusticated door surrounds on the inner faces, and the corners are accentuated with in-and-out quoins.

The south elevation is four stories tall and has ten bays, highlighted by a pair of curvilinear wallhead gables. It is flanked by three-storey pavilion towers with ogee roofs at the eastern and western angles. The entire length of the ground floor at the rear (south) elevation connects to a single-storey roof of the Parliament Garden Lobby.

The roofs are pantiled with grey slate on the ogee-roofed pavilions, featuring tall end and ridge stacks, coped ashlar skews, and clay cans, along with cast-iron rainwater goods.

Inside, the building has been extensively refurbished, with the ground floor integrated into the Scottish Parliament complex. Timber flooring has been replaced with steel beams and concrete. Some stonework has been left exposed, including bolection-moulded fireplace surrounds on the ground floor, and there are vaulted arches in the former kitchen area.
