Tresco – 97 Elizabeth Bay Road – Elizabeth Bay (often filed under Potts Point) – NSW
Victorian Italianate sandstone villa · Thomas Rowe 1867–68 + Westgarth east wing/garden 1883 · Standing — private · SHR #00780
One of the few MacLeay Point allotments still on its original harbour parcel. Rowe built it for himself, named it after the Scilly isle, lost it financially; Westgarth made the garden and east wing; for a century the Flag Officer slept here opposite Garden Island; then private money again.

Tresco sits high on MacLeay Point with harbour outlook toward Clark Island / Garden Island — the reason the Navy wanted it. High stone wall to Elizabeth Bay Road; terraced lawns to the water. Rare intact original subdivision parcel among 20th-century apartment walls (SHR rarity).

Architecture & interiors
Victorian Italianate sandstone: hipped slate roof, Italianate entrance portico, north verandah to the bay (later enclosed in naval period), cedar joinery, fireplaces to main rooms (SHR). Westgarth east wing and service south wing create the compound plan. Naval-era bedroom reconfigurations and plasterboard ceilings; 1990s conservation reinstated finishes; later private works converted stables to office/cellar and added garage apartment (Wikipedia).
People & anecdotes
Thomas Rowe (1829–1899) — Penzance-born architect-builder, City alderman, first mayor of Manly, founder Institute of Architects NSW; overreach on a natatorium nearly ruined him (agent biography). Named sons after Wren, Leonardo, Ruskin — and Tresco. George Westgarth — Australasian Steam Navigation manager; the garden-and-east-wing man. Naval Flag Officers made it Sydney’s “first naval residence” opposite Garden Island (Naval Historical Society).
What stands today
Tresco stands as a private State Heritage waterfront villa. No public access. Views from the water and distant street wall only. Feb 2025 refusal reaffirmed that new houses on the curtilage would permanently harm historic, aesthetic and rarity values — report the decision, don’t re-litigate.
