Glenrock – Darling Point – NSW

Glenrock – Darling Point / Edgecliff – NSW

Original house 1836 (demolished 1870s) · Second house 1870s / 1876 for John Marks · Standing — Ascham School

Glenrock is a double story: Thomas Smith’s 1830s harbour estate house, then merchant John Marks’s Victorian Italianate rebuild on the same ground. The first Glenrock is gone; the second still stands inside Ascham School, beside Fiona and the Dower House.

At a glance

• Estate: Glenrock Estate, Darling Point — Thomas Smith purchase 1835; original house 1836 (Woollahra)
• First house: Smith / Whistler Smith family home (1840s–1850s); leased to John de Villiers Lamb; demolished 1870s when Marks rebuilt
• Second house: Victorian Italianate for John Marks, 1870s (Woollahra: architect David MacBeath; Ascham history: 1876)
• Estate subdivision: after Thomas Whistler Smith’s death in England 1859 — sites for Fiona (Edward Knox, 1864), etc.
• School chapter: Ascham purchases second Glenrock 1909 (Herbert & Antoinette Carter); still campus fabric (boarding / school use across decades)
• Fate: Second Glenrock stands on Ascham campus (private school — not a museum)

Site & setting

Vast waterfront holding on the Darling Point / Edgecliff slope north of New South Head Road — Cadigal land, later “Mrs Darling’s Point.” Thomas Smith’s grant/purchase anchored one of the peninsula’s great early estates. After 1859 subdivision, Fiona and other villas filled the grounds; Ascham eventually gathered Glenrock, Fiona, the Dower House (Whistler Smith for his widowed mother), and The Octagon into one educational campus.

Architecture & interiors

First Glenrock — early colonial gentleman’s residence (Peacock and other artists sketched the Smith-era harbour house; SLNSW holds related views). Second Glenrock — two-storey Victorian Italianate for Marks (Woollahra); David MacBeath named as architect in council fast facts; Ascham dates the Marks house to 1876. School use has altered interiors across a century — describe fabric cautiously without inventing original room schedules.

People & anecdotes

Thomas Smith and Thomas Whistler Smith — merchant-banking dynasty; Whistler Smith initials carved in rock 1836 still pointed out near the Dower House (Ascham history). John de Villiers Lamb — pastoralist/merchant brother-in-law; lessee in the late 1850s. John Marks — merchant rebuild patron. Edward Knox — CSR founder; Fiona neighbour chapter. Ascham / Carters — 1909 purchase ends the private-mansion chapter and begins the continuous school custodianship that saved the second house.

What stands today

The second Glenrock stands on the Ascham School campus (Edgecliff / Darling Point). It is a working school building — not open as a house museum. Respect school privacy; public understanding comes via Ascham’s published history and heritage listings on the campus group.
