Designs have been revealed for Adelaide's tallest residential tower, the plans to push the architectural envelope stirring some controversy in South Australia.

Adelaide's Pruszinski Architects released plans for the $120 million 123 Flinders residential development.

The construction application lodged outlines a 75m-tall building which will also house offices, restaurants and leisure areas.

"I think as an industry we have some amazing innovators who look to do more with what they've got," Property Council of Australia SA executive director Nathan Paine was quoted in the Adelaide Now.

Architect Paul Pruszinski said the design was intended to attract residents and investors drawn to ultra-modern inner-city living.

"Our research was clear. There is a generation who are keen on city apartment living. They expect contemporary and innovative design to be at the centre of any building on offer,” he said.
