PHM announcement of winning architects



Powerhouse Ultimo is set to undergo a transformation that will celebrate the best of its past with innovative museum exhibition and educational spaces, following the announcement of the winning architectural design for its renewal.

The concept designed by Australian team Architectus, Durbach Block Jaggers Architects, Tyrrell Studio, Youssofzay + Hart, Akira Isogawa, Yerrabingin, Finding Infinity and Arup have been chosen to deliver a visionary world-class museum for the people of NSW.

The design contains expanded museum exhibition spaces, including international museum standard galleries for immersive exhibitions and learning programs. A new urban space connecting the museum to The Goods Line will create a major new public square for Sydney, increasing open public space that will support outdoor programs. The Harris Street frontage will be revitalised with creative studios that will support education and industry programs and will create new opportunities to access the museum’s library and archive.

The Powerhouse Ultimo renewal will reinvigorate one of Australia’s most revered museums, offering incredible museum experiences, expanded exhibition spaces, that will provide new levels of access to the Powerhouse collection. The design will enable the museum to showcase international exclusive exhibitions and programs that support the creative industries.

The new Powerhouse Academy will offer a rooftop camp for secondary and tertiary students from regional NSW and beyond, providing an immersive learning experience in the heart of the city. This will provide a range of new opportunities for young people right across the State to engage with and explore the Powerhouse Ultimo’s internationally renowned exhibitions.

“With a bold, defined approach to Country-centred design that is sensitive to the heritage of the site, and inspired by the memory of local sandstone escarpment, the winning scheme is in essence an Acknowledgement of Country in practice,” said Powerhouse Director, First Nations, Emily McDaniel.

The Powerhouse Ultimo renewal is part of the NSW Government’s record investment in cultural infrastructure, reinforcing Sydney’s reputation as a global cultural destination.

The winning Design Team have created a deeply considered response to the Ultimo site, honouring the history and heritage of the Powerhouse museum whilst simultaneously reimagining how the Powerhouse can continue to engage communities and visitors into the future.

The internationally distinctive design will achieve a world-class museum that will fortify the Powerhouse Museum’s role, at the forefront of global contemporary museum practice. We look forward to collaborating and consulting with the community as part of Stage 2 State Significant Development Application which will commence early in 2023.

Our project acknowledges Country as our inspiration and narrator, restoring a natural and intuitive experience of the city; walking with, rather than on, Country.

We propose a new relationship to the heritage fabric. ‘Leaning back’ to allow the full heritage facades to be seen, creating a continuous walkable sky-expanding gorge between old and new, from the Creative Courtyard to the Goods Line Terrace. The new building re-sees the heritage fabric and city beyond from multiple levels of this escarpment – from uses, circulation, terraces and gardens. Respectful and immediate, the new building lives alongside the Powerhouse core, a powerful embodiment of both geography and backdrop.

Our team is dedicated to exceeding business-as-usual by delivering a world-leading environmental outcome. We want to set an example: a museum that is energy net positive, water neutral and zero waste – on site, without investing in offsets.

Our design honours and is framed by the wider landscape, a cultural topography, that operates at the largest scale of geological and hydrological systems. This biophysical context of the living landscape organises the public domain and buildings into an experience that is clear and legible for all who visit and use the museum; as the ridgeline, the escarpment and the valley terraces. This place is a creative field beyond its walls, engaging the ever-changing life of the museum with the life of the modern city, connected to, and in tune with, the ancient rhythms of Country.

The Jury was impressed with the quality of the design proposals for the Powerhouse Ultimo Design Competition and commends all competitor teams for their immense work and the careful thought and energy given to their submissions. After thorough deliberation and unanimous agreement, it is with great pleasure that the Jury congratulates the design team which comprises the following practices: Architectus, Durbach Block Jaggers Architects, Tyrrell Studio, Youssofzay + Hart, Akira Isogawa, Yerrabingin, Finding Infinity and Arup.

The winning scheme is underpinned by a compelling and coherent vision for the renewal of the Powerhouse Ultimo site and the broader precinct. The design approach centres on making subtle moves appropriate to the site – at times via gentle intervention and repair, at others through ambitious moves that enable the site to be ‘unlocked’ to provide a distinctive and highly functional museum experience. The proposal supports the Powerhouse vision of generous public connectivity and access through and within the site, and its materiality and scale respond sensitively to the surrounding Ultimo context.

Designing and connecting with Country strongly informed the conceptual development of the project and is meaningfully embedded in all aspects of the architectural, functional, landscape and urban response. This proposal composes a family of strong masonry buildings which, through the exploration of form and detail over time, reflect and respect the heritage, ethos and future of this innovative institution.
