Humbie House

Humbie House is a late 18th century, two-story, three-bay house that has undergone several later additions and alterations. A single-story wing to the east was likely raised rather than added, and was extended to two stories in 1863, when the front elevation was reversed and a porch was built. Another two-story wing was added to the opposite side in 1901. The house is constructed of pink sandstone rubble with cream ashlar dressings.

The north elevation, originally the rear of the house, features a large, rectangular porch projecting centrally, topped with an ashlar parapet that is raised in the middle with a blank panel. It has a moulded door surround for a two-leaf door. A low, curved addition extends to the east of the porch, with a small window set in the re-entrant angle, potentially leading to a cellar or basement. A stair window is centrally placed, with windows on each floor in the flanking bays. A recessed wing to the left has irregular windows, while the wing to the right is more recessed, with lower eaves and irregular windows, one at ground level dated 1901 on its lintel.

The south elevation has an architraved doorway with a short flight of steps. Windows are placed in the flanking bays and in each bay on the first floor. A full-height, five-light canted bay with a crenellated parapet is recessed to the outer left of the 1901 addition, with a steeply pitched gabled dormer above. The line of a former single-story wing is visible in the subtly recessed bays to the outer right, with irregular windows, one large tripartite window on the first floor.

The west elevation features a timber lean-to conservatory at ground level, two first-floor windows, and a smaller attic window. The east elevation has a largely blank doorway to the left of centre and three linked pointed arch windows to the left; a timber shed abuts to the right.

Twelve-pane sash and case windows are predominant throughout the property. The roof is covered in grey slates, and ashlar dressings are used on the end stacks, with the original cans retained. Skylights have been added to both the north and south sides.

Coped ashlar quadrants with corniced drum piers and square outer piers are situated to the south of the house.

A large sawmill is located to the north of the house, set on an incline beside a former culvert; it is likely late 18th century and warrants note, although the water wheel is no longer in place. The site of the house is known as Shillinghill.

The 1863 additions were made by the 8th Lord Polwarth, and those of 1901 by the 9th Lord. The locations of the current skylights were previously filled with gabled dormers. A map of Haddingtonshire from 1799 by William Forrest shows Humbie House as the property of Hepburn Esq. A former lodge to the south has been demolished.
