Description

Isabella House is a house with offices and a shop, dating from around 1840, with later 19th-century additions. The front block is compact, three stories high, with a lower wing attached to the left and a large wing to the right. The front has three bays and is in a late Georgian style; the wing is in a High Victorian classical style. The front has three windows, grouped two and one, with plain sashes set in reveals that have stop-chamfering. There is a paired sash window at the first floor on the right. A five-panel door, topped with a cornice on carved consoles and incorporating a carved date, sits between the first and second bays. A shopfront from the 20th century is to the right of the door. The building features a coved cornice, a blocking course, and a parapet. The single-story wing to the left has four sashes in moulded architraves and a panelled door within an architrave with a moulded pediment. It has a moulded cornice with a blocking course incorporating balusters above the windows, and abuts the flank of 79 Church Road. The long return to the right has two, three, and two windows. The sashes have a plain lower half and a barred upper half, with shouldered lintels and splayed, flush sills. Round arches with flush keystones are between the first and second bays at each level, with a flush gable at ground floor containing a pair of plank doors and blind features on the first and second floors. An eaves stack with a gable is to the right. The gable end return is similarly detailed. The interior has not been inspected.
