28 Mistral Avenue, Mosman, heritage-listed residence located in Mosman, New South Wales

28 Mistral Avenue is a two-storey shingle-style house in Mosman designed by E. Jeaffreson Jackson around 1900, with North American influence. It stands above street level behind a stone retaining wall and keeps its timber shingles, casement windows and terracotta tiles. A grass tennis court occupies the front garden as the garden front.

Built around 1900 by architect E. Jeaffreson Jackson, whose North American-influenced designs are rare in Sydney, this house was added to the New South Wales State Heritage Register in 1999. Its listing recognizes the architect's distinctive contribution to early 20th-century residential design and the house's well-preserved original features.

The house is also known as 8 Magic Grove and forms the Magic Grove Group with its neighbour at 17 Calypso Avenue, the only two houses in the group, both designed by E. Jeaffreson Jackson. The name Magic Grove is not explained in the heritage record. The Jesson family, who let the house for years before the Budds bought it, installed the grass tennis court that still dominates the front garden.

The house stands above street level behind a stone retaining wall, and the lawn tennis court occupies the front garden, so the court and facade are what passers-by see from Mistral Avenue. It remains a private home and is not open for interior visits. The neighbouring house at 17 Calypso Avenue, opposite, was designed by the same architect.

The house is one of two in the Magic Grove Group, a classified area of the National Trust of Australia (NSW); both were designed by E. Jeaffreson Jackson and stand on opposite corners of Mistral Avenue, giving the street a paired townscape element. Only nine of Jackson's residential designs are known to survive in Sydney, three of them in Mosman.
