When art meets architecture in Tasmania

On Tasmania’s dramatic Tasman Peninsula, near Koonya, three strikingly different buildings emerge from the rugged landscape, forming a trio of structures that demonstrate how art meets architecture.

Known collectively as Triptych, this ambitious project by Room 11 Architects is more than just a contemporary residence and a guest house – it’s a conversation piece and experience rolled into one.

The unrivalled property was showcased on Season 11, Episode 1 of Grand Designs Australia and has graced the cover of Tasmania Living magazine. Triptych is fun, a little bit quirky, and a big helping of eccentric.

Completed in 2023, this rare slice of real estate, spanning more than 40 hectares in a remote part of the Apple Isle, has now come to market with price expectations of $3.5 million. It will go under the hammer on June 15, marketed through Georgie Rayner of The Agency Hobart and David Medina of Sotheby’s International Realty NSW.

Crafted by Room 11’s design duo, Thomas and Kate Bailey, Triptych was commissioned by Sydney-based art director and writer Jonathan Kneebone. He wanted a regional retreat that would not only pay homage to the land but also push boundaries and the expectations of what a country house should be.

The result is a trio of individual buildings – each with its own distinct design, offering separate purposes surrounded by the pristine wilderness.

Blunt House, the main three-bedroom residence, is almost invisible at first glance. The low-lying structure is seemingly embedded in the hillside, a concrete construction disappearing into the earth, then cantilevered out towards the horizon.

In a bold decision by the architects, the long rectangular floor plan only allows one room – the main living space – to capture the stunning ocean backdrop overlooking Norfolk Bay.

The gun barrel view of the bay beyond the rolling hills was the inspiration for the architects, who have admitted that they began with the grand window snapshot in mind and then designed “backwards”.

Upon arrival, visitors descend via a dark, leather-lined corridor before entering the iconic lounge area, which offers unparalleled views.

Each bedroom is unique, with one featuring sheep skin-lined walls, while another has “upside down” windows best experienced when lying down on the bed.

The primary bathroom features a bath that is recessed into the floor, with mirrors embedded under the vanity for a distinctive perspective on the landscape, while soaking in the tub.

Packed with bespoke design elements created to withstand the elements, the main house’s brutalist concrete walls are punctuated by a custom ventilation system that harnesses the cross-flow from prevailing northerly and southerly winds, without interrupting the aesthetic.

A second building, known as The Glass House, is a one-bedroom guest pavilion perched higher on the sloping block, offering an entirely different experience to the main house. It has 360-degree views and walls of glass with almost nowhere to hide.

Finally, the third structure is The Folly, a mysterious cube with a rust-like Corten steel door opening to reveal what appears to be an old silo, but in actual fact, is a purpose-built contemplative space hiding a shallow reflective pool that simply mirrors the sky above.

The two designer residences on separate 20ha titles are 3.5 km from the coastal town of Koonya, 18 km from Port Arthur and 90 km from Hobart.

Triptych at 67 & 75 Grooms Hill Rd, Koonya is listed for sale with Georgie Rayner from The Agency Hobart and David Medina of Sotheby’s International Realty. The price guide is “more than” $3.5 million, and the auction is scheduled for July 14.

Australia’s major CBD office markets are recording some of their strongest rental growth since the pandemic, with businesses increasingly prioritising premium office space despite elevated geopolitical and economic uncertainty.

Knight Frank’s Australian Office Indicators Q1 2026 report found net effective rents in Sydney and Melbourne CBDs rose at their fastest annual pace since COVID-19, increasing 10.2 per cent and 6.8 per cent respectively over the 12 months to March.

Brisbane posted the strongest growth nationally, with net effective rents climbing 11.7 per cent over the same period.

The report points to a widening divide between prime CBD office towers and secondary office stock, as occupiers increasingly focus on quality, location and workplace amenity when making leasing decisions.

Knight Frank Senior Economist, Research & Consulting Alistair Read said demand remained heavily concentrated in premium assets within core CBD precincts, helping drive stronger rental growth in top-tier buildings.

“Occupier demand continues to be heavily concentrated in the most desirable CBD precincts and the highest-quality buildings, accelerating a sharp divergence between core and non-core markets,” Mr Read said.

According to the report, Sydney’s Core precinct and Melbourne’s Eastern Core significantly outperformed broader CBD markets over the past year.

“In Sydney’s Core precinct and Melbourne’s Eastern Core, net effective rents surged 14.3% and 16.1% over the past year, significantly outperforming the rest-of-CBD precincts,” Mr Read said.

The rental gap between prime and non-prime office locations has also continued to widen sharply.

“As a result, core CBD rents are now 54% higher than non-core locations in Sydney and 93% higher in Melbourne, highlighting the growing premium placed on amenity, accessibility and workplace quality,” he said.

Knight Frank said the strong rental growth across the major CBDs was being underpinned by a limited supply pipeline, with few new office developments expected to be delivered in the near term.

Mr Read said subdued construction activity was likely to support ongoing rental growth and tighter vacancy rates over the medium term, particularly for premium office towers.

“The combination of sustained demand and declining levels of new development will aid ongoing prime rental growth and lower vacancy rates over the medium term, particularly for best-in-class assets,” he said.

The report noted that current economic conditions were making new office developments increasingly difficult to justify financially.

“Economic rents remain well above expected market rents, making the construction of new office towers largely unviable, and concentrating tenant demand into existing buildings,” Mr Read said.

While suburban office markets generally remained subdued compared with CBDs, Melbourne’s Southbank precinct was identified as a relative outperformer, recording annual net effective rental growth of 2.7 per cent.

The report comes as broader Asia-Pacific office markets continue to stabilise following several years of disruption linked to hybrid work trends, inflation and rising interest rates.

Knight Frank’s separate Asia-Pacific Q1 2026 Office Highlights report found Sydney and Brisbane were among the strongest-performing office rental markets in the region, behind only Bengaluru and Tokyo for annual prime net face rental growth.

The Asia-Pacific report also found 18 of the 24 cities monitored across the region recorded stable or increasing rents in the first quarter of 2026, even as geopolitical uncertainty intensified following escalating conflict in the Middle East.
