97 and 99, Park Avenue

97 and 99 Park Avenue are a pair of semi-detached houses built in 1935 by Connell, Ward and Lucas, with minor alterations. The houses are constructed of painted concrete and stand three storeys tall. They feature a symmetrical elevation with four asymmetrical bays, where the two central bays are wider and project forward on the ground and first floors. The outer bays include garages that also project forward, and there are open porches at the angles with the garages.

Designed in the Modern Movement Style, the houses have metal-framed casement windows and glazed doors. Each house has a late 20th-century entrance door and continuous windows on the ground and first floors, with a door on the inner side of the first floor leading to a solid-fronted iron-railed balcony. On the second floor, each house has an open sun deck. The outer-stair bays were intended to be fully glazed but were built with a central infilled panel. The left-hand garage is now part of the house. The flat roof features a central chimney.

At the rear, the upper floors of the central section are recessed. There are three-light kitchen windows with late 20th-century double doors on the inner sides, and on the first floor, there are three-light windows in the outer bays and continuous windows in the central bays. The interior of No 99 includes an original living-room fireplace with a bow-fronted flue and flanking curve-cornered cupboards. Between the kitchen and dining room, there is a pivoting door with semicircular shelves and a hatch, along with drawers that open into both rooms. The dog-leg stair has a solid-walled balustrade and a glazed door leading to the stairs up to the sun deck. The interior of No 97 was not inspected.
