Domain Park Flats, Residential tower in South Yarra, Victoria, Australia.

Domain Park Flats is a 20-story residential tower in South Yarra with north-facing balconies offering views toward the Royal Botanic Gardens and Port Phillip Bay. Inside, apartments range from two to four bedrooms, served by two elevators arranged along an east-west floor plan.

Built between 1960 and 1962, the tower became Victoria's tallest apartment building when it opened. Its construction methods set new standards for how high-rise residential buildings could be erected in Australia.

The name Domain Park Flats reflects the building's position facing the Domain parkland and Royal Botanic Gardens. Conceived as 'own-your-own' luxury housing, it drew buyers with a choice of four interior colour schemes prepared by Boyd. Some nearby residents formed an association to oppose further high-rises along the park front.

Domain Park Flats is a private residence at 193 Domain Road, South Yarra, so the building and its balconies are not open to visitors. The 20-storey slab can be seen from the Royal Botanic Gardens and from Domain Road; the north facade, with its varied windows and balconies, faces the gardens.

The two lift towers were built first by slip forming, then used to hoist materials for the rest of the structure. Critic Arnold Shore called them "monstrous excrescences" in The Age; Boyd answered that hiding structure was the real offence.
