111+222 is a mixed-use development in Brisbane consisting of two buildings: a 36 level 45,000sqm commercial office building at 111 Mary Street, and a 92 level five star hotel and residential tower at 222 Margaret Street. The lowest four floors will form a street scaled podium designed to provide an active ground plane with a public through site link between Mary and Margaret Streets. It has an eight level basement car park accommodating 980 cars. The basement has been excavated, and Development Approval is pending.
The development has been created to efficiently maximise its height, delivering a building that is tall, environmentally sustainable and responds to the sub-tropical climate of Brisbane.
At 300m in height to the architectural top of the building 222 Margaret Street will be one of the tallest buildings in Australia with the highest occupiable penthouse. Situated 200m from a future metro rail station on the edge of the CBD, residents will have easy access to mass transport and to walk to work in the city. The high density mixed-use development incorporates living/working/shopping and accommodation, creating a microcosm of a sustainable city.
Renewable technologies are integral to the design, and respond to the unique characteristics of the development. The north facing roof top of 111 Mary Street is angled to incorporate a photovoltaic array, while the roof of 222 Margaret Street incorporates wind turbines. A gas fired trigeneration plant will provide on-site power generation.
The tower’s façade has been designed to deal with the low angled sun, glare, and tropical downpours; while working with contemporary glass curtain wall technology. A floor-by-floor system of layered and angled planes of glass creates a façadetype expression that allows windows to operate in tropical downpours; minimises solar heatload, sheds wind, and reduces glare. The result is a unique contemporary interpretation of sub-tropical typologies.
