Rosemont, Woollahra, Heritage residence in Woollahra, Australia

Rosemont is a sandstone residence at 14 Rosemont Avenue, Woollahra, built around 1857 for Alexander Campbell, who acted as his own architect; the stone was quarried in the grounds and the cast iron came from Peter Nicol Russell's foundry. The house stands on a long, tree-shaded avenue entered between curved stone walls and miniature stone pillars, one of the few surviving relics of the original estate.

Alexander Campbell, a merchant banker and former member of the New South Wales Legislative Council, initiated construction of Rosemont in 1857 using stone quarried from the property itself. The building subsequently shaped the architectural character of the Woollahra area.

The house's name and grounds recall Alexander Campbell's garden, which stretched to Trelawney and Ocean Streets and Edgecliff Road before subdivision created Rosemont Avenue. In the 1860s Campbell leased garden plots to friends, and cottages such as Kalingra, Kelston and Lillingston rose there. Later, Mrs J.T. Walker gave visitors bunches of her carnations and roses.

Rosemont stands at 14 Rosemont Avenue, reached by the curved stone walls and miniature pillars of its entrance off the street; the long tree-shaded avenue beyond is one of the few surviving relics of the original grounds. The house is a private residence surrounded by houses built after the 1912 subdivision, so it is viewed from the street rather than entered.

The cast iron for Rosemont's verandahs came from the foundry of Peter Nicol Russell, a Sydney ironmaster whose firm later became part of the engineering company that helped build the Sydney Harbour Bridge. The stone was quarried within the grounds, and Campbell acted as his own architect. Rosemont Avenue itself did not exist until the estate was subdivided.
