Greenoaks - Darling Point

Greenoaks (later Bishopscourt) – 11–21 Greenoaks Avenue – Darling Point – NSW

Built from 1841 cottage / 1846–49 mansion works · Architects J. F. Hilly (1846+); Edmund Blacket (1859–60); Leslie Wilkinson (1935) · Standing — private residence (Anglican Archbishop’s house 1911–2015)

Thomas Woolley’s Percyville cottage became Thomas Sutcliffe Mort’s Gothic showplace — armour, picture gallery, Guilfoyle garden — then, from 1911, Bishopscourt for Sydney’s Anglican archbishops. Blacket’s academic Gothic and Wilkinson’s 1935 wing still read from Greenoaks Avenue. Sold out of church hands in December 2015. The live blog post is almost pure album: keep the pictures; this text supplies the spine.

Site & setting

Yarranabbee / Darling Point — Gadigal and neighbouring clan Country; heavily timbered until New South Head Road and 1830s grants. Mort’s Greenoaks sat among Darling Point villas (Swifts, Carthona, Lindesay). Michael Guilfoyle landscaped from 1849 — SHR: “leading and model private garden of NSW.” Double Bay “Exotic Nursery” on Mort land supplied plants. Much garden lost to Greenoaks Avenue subdivision (1911); remnant trees and romantic slope survive around the house (SHR).

Architecture & interiors

Dressed sandstone, steep slate roofs, stepped gables, Victorian Tudor windows and carved doors; Mort arms carved in stone (SHR / RNE notes). Blacket porte-cochère in Gothic chapel form (1860); grand stair with stained glass; panelled library; picture gallery once showing ~200 works and armour, open monthly to the public (SHR). Wilkinson’s 1935 wing extended over former stables. Later church-period alterations (Clamp 1911–13; Ross & Rowe; 1965 Fowell Mansfield Maclurcan with Wilkinson) changed kitchens, porte-cochère (removed 1965), and private apartments — flag complexity rather than inventing a single “original” interior.

People & anecdotes

Thomas Sutcliffe Mort — auctioneer, wool sales innovator, refrigeration pioneer, Mort’s Dock, AMP founder, St Mark’s Darling Point benefactor (ADB / SHR). Married Therese Laidley (link to Rosebank’s Laidley world). Michael Guilfoyle — Chelsea-trained nurseryman; Greenoaks made his colonial reputation (SHR). Edmund Blacket — friend and architect. Archbishops from Wright through Davies used the house; DoS lists seven by 2013 before the sale saga.

Sydney Morning Herald “Progress of the Suburbs” (13 Sep 1913) called Greenoaks the show place of Darling Point and finest Elizabethan specimen in the colony (quoted in DoS).
