Elizabeth Bay House – 7 Onslow Avenue – Elizabeth Bay – NSW
Built 1835–1839 · Architects John Verge & John Bibb (British plan attrib.) · Standing — Museums of History NSW house museum
On the northern edge of Woolloomooloo Hill — before Onslow Avenue, before the flat boom, before Elizabeth Bay meant balcony views for rent — Colonial Secretary Alexander Macleay planted a private botanic garden on fifty-four acres of harbour rock and bush, then raised what contemporaries called the finest house in the colony. The oval saloon still soars. The planned Doric colonnade never arrived. The acres became a suburb. The house became flats, a squat, a reception venue — and, after one of Australia’s first scholarly restorations, a public museum. Ambition, insects, bankruptcy, and a staircase like an arum lily: welcome to Elizabeth Bay House.

### Site & setting
The Aboriginal name recorded for Elizabeth Bay is **Gurrajin** (official dual name with the European placename). This was Cadigal Country on Sydney Harbour — fishing ground, contact landscape, and, under Governor Macquarie, the site of **Elizabeth Town**: bark huts and a fishing settlement associated with **Bungaree**’s group (c.1815–1820s), downslope toward today’s Beare Park. Governor Brisbane later eyed the bay for an asylum. Instead, soon after Alexander Macleay arrived as Colonial Secretary in January 1826, Governor Darling granted him about **fifty-four acres** with commanding harbour views — a grant that drew heated newspaper comment for alienating public land.
Macleay did not clear-fell and start again. With assigned convict labour and gardener **Robert Henderson**, he kept indigenous trees where he could, cut picturesque walks, and layered in a private botanic garden of walls, grottoes, ponds, gravel paths, Cape bulbs, and fruit from half the globe. *The Sydney Gazette* (May 1831) already sang the transformation. Joseph Hooker in 1841 called it a “botanist’s paradise.”
Subdivision from the 1840s onward — and especially after William Sharp’s death — carved the estate into the suburb we know. Onslow Avenue sliced the famous front lawn; Billyard Avenue edged what became **Arthur McElhone Reserve** (City of Sydney, landscape architect Ilmar Berzins, 1948–50). Today the villa sits tight among flats, looking north to a fragment of garden and the harbour beyond. The grotto and stone walls survive as rare fabric of that early landscape (separately listed).

### Architecture & interiors
Elizabeth Bay House is a two-storey Greek Revival villa on a centralised Palladian plan — square vestibule opening into an **oval, domed saloon** where a **cantilevered Marulan sandstone stair** rises to an arcaded gallery under a lantern. Cedar joinery, blackbutt floors, Grecian architraves, laurel-wreath plasterwork, imitation-bronze cast-iron balusters: this is the interior that made the house’s reputation. ADB Verge called the hall one of the richest and most spatially dramatic interiors in early Australian colonial architecture.
The exterior is another story. Soft Sydney sandstone under sand paint; blind windows for symmetry; a light iron-and-wood portico that was **not** part of the 1830s design. The house was meant to wear a **single-storey Doric colonnade** on three sides — the sort Conrad Martens painted into existence, and the sort Verge built at The Vineyard for Hannibal Macarthur. Money ran out; the colonnade never rose; the façade stayed severe. That incompleteness is not a romantic myth — it is fabric fact, and SHR significance turns on it. The small portico arrived only in the Macarthur-Onslow years, when open French windows otherwise dropped toward a sheer edge.
Service wings and stables are gone (kitchen wing sacrificed in the 1927 carve-up). Cellars remain under the house — two unconnected wings in the SHR description — but treat 1920s press tales of convicts “quartered” there as colour, not conservation evidence. Assigned convict labour built the estate; that much is documented.
**Architect note:** Prefer SHR wording: unknown British designer / imported scheme, realised under **Verge** and **Bibb**, built by **James Hume**. Do not claim a simple “Verge alone” authorship. Interior loosely compared to Henry Holland’s Carlton House for the Prince Regent.
Winter-solstice sunrise bisecting the house front-to-back is a documented observational effect (Malone / Sydney Living Museums); no contemporary document yet found that proves it was intentional — say “aligned” and flag the gap.
Museum interiors today interpret **1839–1845**: inventories, paint scrapes, and furniture trails (including pieces sold to Government House) guide the refurnishing — not a fantasy of how rich Macleay *wished* to live after the crash.

### People & anecdotes
**Alexander McLeay / Macleay** was Colonial Secretary, Linnean secretary, Fellow of the Royal Society, and a collector whose insect cabinets were said to be unmatched in private hands in England. He worked twelve-hour days for Darling, fought Bourke to a standstill over education and exclusivism, lost office in 1837, took the Speakership of the part-elective Council in the 1840s, and still found time for bulbs, botanic-garden politics, and a harbour showpiece he could not afford. Spelling: ADB files him as **McLeay**; the Australian family settled on **Macleay**.
**Eliza Macleay** ran the household through the rise and the bitterness of the fall. **William Sharp Macleay** — Cambridge scholar, pre-Darwinian theorist, recluse — paid the debts, sold the drawing-room glories, posted dog-warning signs at the boundary, and kept the house as a scientific salon until 1865. Cousin **Sir William John Macleay** and **Susan** (Deas Thomson’s daughter) turned the collections into a public legacy: the **Macleay Museum** at the University of Sydney. Through daughter Rosa’s Onslow marriage, the house later brushed the **Macarthur-Onslow** world of Camden Park.
Twentieth-century chapters are pure Sydney scrapbook: Michaelis family life within walking distance of the Great Synagogue; Snow and the Estates company (Leslie Wilkinson among shareholders); Charm School artists camping in a decaying mansion; reception-house glamour; fifteen flats without gutting the fabric; then the conservation rescue that helped invent the Historic Houses Trust.
No **Mitchell** owner belongs in this story — only the **Mitchell Library**, which holds the plant and seed books.
