A design competition has been launched to transform a civic hub in northern Sydney into a new gateway for culture and commerce.

The competition to revitalise the City of Ryde has invited “the world’s most talented and creative architects” to submit “new, unexpected and iconic solutions to engage the community” and unlock the potential of the site – located on a prominent ridgeline with views of the surrounding Blue Mountains.

The hub is the current location of the local government’s headquarters, but these are likely to be relocated with the City of Ryde soon set to merge with the New South Wales State Government.

The city is seeking a replacement use for the area “that builds upon its significant cultural history and location,” and design entries are encouraged to include multi-functional indoor spaces for community and private hire, public open space, housing and infrastructure which better connects the site with the rest of the city, particularly for pedestrians.

“Great Architecture can rejuvenate a city and it takes creative minds to imagine and shape a new place,” said NSW government architect and competition jury chair, Peter Poulet.

“We want ideas with flair and innovation to guide the development of this famous site, for the benefit and pride of future generations. Already there is a buzz within the architectural community and we are very excited about what will eventuate.”

The architectural contest, called Design our Ryde, is underpinned by the region’s 2025 Community Strategic Plan to ensure lifestyle offerings and economic opportunities are available “close to where people live, work and play.”

The competition is being held in two stages. The deadline for initial submissions is 30 March 2016 and the jury will work with the public to select four shortlisted entries by 13 May. The successful architects will then have the opportunity to revise and expand on their plans before a final winner is chosen by 8 August.

The successful scheme will be considered for feasibility and will be used as a starting point in discussions over the site’s future.
