Montaza House and Garden Walls to Front

Montaza House is a house built around the late 18th century. It is constructed from red granite ashlar with granite dressings and has a scantle slate roof with brick chimneys at the gable ends. The house features cast-iron ogee gutters. The layout includes a double depth plan with two front rooms, a through passage slightly left of the middle, and two service rooms at the rear.

The exterior is two storeys high and has a nearly symmetrical three-window south front, which includes a blind window opening above the doorway. The ground floor openings have keyed flat arches, and there is a 20th-century ledged door along with four-pane horned sash windows. The original sashes and casements with small panes can be found at the rear, along with a ledged door.

The interior includes a rectangular garden at the front, which is bordered by high side walls and a low ashlar plinth that runs parallel to the house. This plinth features a central gateway with round-headed granite monolithic piers. There is a wooden fence on top of the plinth, which originally had iron railings.
