Finnart House, Arrochar Road, Finnart

Finnart House is a large, asymmetrical house dating from the 1830s, designed by William Burn. It is constructed of rubble with polished sandstone margins and dressings, featuring a projecting terrace and a single-storey, quadrangular kitchen court attached to the northeast.

The east elevation, the main entrance front, consists of a three-bay main block to the left and a more advanced three-bay block to the right, with the kitchen block projecting further to the outer right. A blocked, gabled ashlar porch is centrally positioned on the left, featuring an elaborate escutcheon on the keystone. A central entrance has a piend-roofed, stugged sandstone porch with a round-headed door surround, a two-leaf wooden door, and flanking windows. A dormerheaded window sits above the entrance. The right-hand section features a gabled block with symmetrically disposed windows, and a boarded door with a dormerhead on the return. A kitchen wing extends in front of the right side, with dormerheads above.

The west elevation exhibits three wide bays, with a canted window at the centre, featuring a leaded half-piend roof, and a dormerhead above. Flanking this are full-height, canted bays that sweep to a square at gablehead. A broad, slightly projecting bay breaks the eaves on the left return, containing tripartite windows and a narrow window spanning the corner. To the left is a recessed, lower four-bay block; a slightly-advanced, broad gable with bipartite windows at ground and first floor sits to the outer left. Three near-symmetrical bays are aligned to the right, featuring dormerheads. A window has been altered to a door in the penultimate bay to the left, and a tripartite window is at ground level.

The north elevation shows the two-storey main block of the house to the right, and a single-storey, four-bay kitchen block to the left. A blank bay is on the outer right of the main house, and a broad, advanced gable to the left has two windows at ground level and two small, closely grouped windows at gablehead, sharing mullions. The kitchen block to the left features a slightly-advanced gable to the outer left, with symmetrically disposed windows in the bays to the right.

The south elevation presents three bays with a canted window to the outer left and a window to the outer right, three dormerheaded windows above.

The interior was not inspected in 1993.

The house has 12-pane sash and case windows, with some plate glass sash and case windows. The roof is covered in grey slate with lead flashings. Tall corniced ridge stacks sit on pedestal bases, topped with terracotta cans. Steps with ashlar dies and slab coping lead to the west of the house, while plain ashlar steps extend to the north.
