343 George Street is one of Sydney's most distinguished commercial buildings.
Erected in 1925 in the interwar commercial palazzo style, it has occupied a commanding position on George Street — Australia's oldest thoroughfare — for more than a century.
Heritage-listed and structurally formidable, the building sits steps from Martin Place, the civic and financial heart of Sydney's CBD.
After a meticulous restoration, it now enters its most significant chapter as the home of Tajon Luxury Offices — Australia's first Private Workplace Residence.
Some buildings are designed for a moment. Others become part of a city's identity.
343 George Street is completed during Sydney's interwar building period, establishing itself as a significant example of commercial palazzo architecture.
Classical proportions, a defined base-shaft-capital facade and ornamental stonework give the building the permanence expected of the era.
For decades, 343 George Street served Sydney's professional class quietly and without fanfare.
Its use remained commercial from the day it opened, allowing the building's original proportions, structure and architectural character to become part of the fabric of George Street itself.
The significance of 343 George Street is structural.
The proportions of its original floors. The weight of its stonework. The ceiling heights that modern developments cannot replicate.
The palazzo remains.
Everything added serves it.
The restoration has been led by Natashia Steed, whose previous work includes The Bureau at 25 Bligh Street.
Original fabric has been honoured, details hidden by decades of tenancy have been restored, and contemporary luxury has been introduced without competing with the architecture.
The result is not simply a renovation. It is a building brought back to its original standard — and then elevated beyond it.
In August 2026, 343 George Street opens as the home of Tajon Luxury Offices — Australia's first Private Workplace Residence.
A century-old building enters a completely new chapter without losing what made it significant in the first place.
Designed in the commercial palazzo style, 343 George Street carries the visual weight and permanence of early twentieth-century Australian architecture.
The restoration was approached with restraint.
Rather than erase the history of 343 George Street, the project works within the discipline of the building itself.
Original architectural fabric has been retained. Details hidden through decades of tenancy have been brought back into view.
Contemporary materials and services have been introduced carefully, creating a workplace that feels entirely current while remaining unmistakably connected to its past.
Tajon was co-founded by John Caldwell, Group CEO of RWR Group and 2014 Australian of the Year (Victoria), and Natashia Steed.
The idea was straightforward: the best professionals deserve a workplace that reflects the standard they hold everywhere else in their lives.
Each founding tenant occupies a private suite — their own office, boardroom, bar, meeting room and lounge.
There is no shared desk. No open plan. No compromise dressed up as community.
Martin Place is not merely nearby. It is the reason this building exists.
When 343 George Street was built in 1925, Martin Place was already the centre of Sydney's financial and civic life.
A century later, that position remains. The Reserve Bank of Australia, the GPO, the Cenotaph and the country's major institutions are all within minutes.
343 George Street occupies the desirable stretch between Martin Place and King Street, with Circular Quay and Pitt Street Mall within easy reach.
Tajon does not describe itself in the language of commercial real estate because it is not commercial real estate.
It is a private workplace for people who have spent their careers building something that matters — and who will not accept a workplace that falls below the standard they set everywhere else.
