A showcase of 57 proposals for redesigning Brisbane city are on display for public review as part of the city’s “Inner Spark” campaign.

Brisbane City Council asked design studios and industry bodies to submit imaginative ideas for turning Brisbane into a city ready for the world stage. More than 600 design and architectural ideas have so far been submitted, 57 of which are presently viewable on the council’s website.

The design brief had seven key themes for promoting inclusion and accessibility; enhancing connectedness; fostering creativity; enriching beauty; facilitating future growth; incorporating clean, green and sustainable design; and responding and adapting to challenging conditions.

Some of the more intriguing proposals include an adventure flying fox connecting River Terrace to the City Botanic Gardens and a plan called “Buildings that Breathe” which involves planting rooftop gardens on every major skyrise building in the CBD.

Lord mayor of Brisbane Adrian Schrinner said the welcome influx of ideas will “start a conversation” about what the city may look like in the future.

“We asked some of Brisbane’s best and brightest to come forward with big and bold ideas that can transform those areas of our city that are popular with residents and visitors alike

“Like Expo 88 transformed the industrial site we now know as South Bank, we wanted to start a conversation on how Brisbane 2032 can revolutionise other parts of our city, particularly those areas in and around Games venues,” said Schrinner.

The set of proposals will remain open for public comment until 25 September on the Brisbane City Council website.

In the meantime, Brisbane’s first “townhouse in the sky” development has been approved.

Sydney-based developer Pyco Group has won approval for its Nouveau apartment building on Anstey Street at Albion.

According to a report in The Urban Developer, the building will feature arched terraces and a brick foundation that reflects the industrial heritage of the suburb.

Realm Projects managing director and project marketer for the development Shane Foley said the townhouse in the sky concept is the first of its kind in Brisbane and is part of the city’s vision of the future.

“This hasn’t been done before in Brisbane, it’s uniquely designed for this site. It’s taken that traditional concept of a townhouse and put it in an apartment building,” he said.
