Mount Rosa, 45 Seafield Road, Broughty Ferry, Dundee

Mount Rosa is an Italianate villa dating to circa 1853, designed by James MacLarn, with a late 19th-century extension to the north and east. The house is constructed of ashlar stone, with snecked rubble to some areas, and harl (roughcast) to the west and original north elevation, all beneath a slate roof. The windows are mostly 2- and 4-pane sash and case windows, and the south elevation features richly patterned cast-ironwork. Deep eaves are visible, with exposed purlins at the gables, and the corniced stacks have decorative cans, harled to the west and northwest.

The south elevation is asymmetrical, featuring a single-storey entrance porch set between and linking with two advanced gabled bays. The porch has a 4-panel door with a fanlight and is topped with a squat cast-iron parapet with four ashlar dies. A window is recessed at the first floor. A bay to the left has a two-storey, tripartite canted window, with a cast-iron balcony on the first floor; the left return elevation has a 10-pane window, and anthemion pattern cast-iron snow catchers are present at the roof. To the right is a projecting single window at ground floor, also with a parapet similar to that of the porch, and a first-floor window with moulded architraves and a corniced lintel. The bay furthest to the right has a tripartite canted window at ground floor and a cast-iron parapet, with a gabled dormerhead above, containing a keystoned segmental window.

The east elevation is two-bay with an M-shaped roofline. An advanced gable is located to the right, with a single-storey projection featuring windows at ground and first floors that form part of a two-storey canted window at the re-entrant angle. A recessed gable to the left has a window at first floor.

The north elevation shows the original house slightly recessed to the right, with various single-storey projections and windows, alongside a later block to the left.

The interior retains a well stair with mannered turned balusters, alongside some original marble, stone, and timber fireplaces, original cornices, ceiling roses, and compartmentalised ceilings.

A conservatory is located at the west, with a harled brick base and anthemion pattern cast-iron brattishing at the eaves.

Gatepiers and a boundary wall mark the property. Two margined ashlar coped gatepiers, two further plainer gatepiers, and an entrance gateway are located on Seafield Road. Two ashlar capped gatepiers with spur stones are at the corner of Seafield Road and Davidson Street. The boundary wall is built of snecked rubble with rounded coping at Davidson Street, random rubble at Seafield Road, and a terrace.
