Tyninghame Mains

Tyninghame Mains is a building dating from around 1800, which incorporates an earlier farmhouse and was extended in the mid-19th century to serve as a two-storey factor's residence. The structure features random rubble and harled surfaces on the south elevation, while the mid-19th century work is constructed from squared and snecked red sandstone.

The south entrance elevation, dating from circa 1800, is symmetrical with three bays and showcases classical details. It has raised quoins, a pilaster and cornice door surround, and a flush panelled door with a decorative fanlight. Tall windows are positioned at the ground level and in each bay on the first floor, grouped towards the center. There is a recessed bay to the outer right with a first-floor window.

On the north rear elevation, a wide stair block projects at the center with a window to the right. There is an advanced wide extension from around 1840 to the outer right, featuring French windows to the left and a central wallhead stack. The earlier bays to the left have irregular and altered openings, with piend-roofed outbuildings added to the outer left at ground level.

The west elevation has a mansard gable wall formed by bridging the gable end of the earlier house with the gable end of the circa 1800 extension. It includes three window bays, with taller windows at the ground level in the outer bays. There is an advanced extension to the outer left, which has a first-floor window.

The east elevation features a first-floor window to the right of the circa 1800 gable wall, and a single-storey range of estate office abuts at the outer left.

The building has 12-pane glazing patterns in the sash and case windows, with external double glazing added to the west. There are gable wallhead stacks, some made of brick, and the roofs are covered with slate, including piended rear extensions.

Additionally, there is a detached stone cubic sundial with a copper gnomon on each vertical face, set on a circular waisted pedestal and finial, located on a square base at the center of an ornamental pond at the rear of the Factor's House.

The property features ashlar coped retaining walls to the south, adorned with a decorative cast-iron urn and arrowhead railings, along with simple timber gates. Higher boundary walls are present to the east, west, and north.
