Adelaide designers Studio -Gram and Sans-Arc Studio both received prizes at the 2020 Australian Interior Design Awards on the weekend. The national awards ceremony was held online for the first time in its 17-year history.

Melbourne restaurant Di Stasio Citta came out on top for a bold and brutalist design by Hassell Studio, receiving the Premier Award and the Hospitality Design award – tying for the latter with Sydney’s refurbished Hotel Rose Bay.

The 90-year-old hotel, which was updated last year by Sydney’s Richards Stanisich, also took out the NSW award for Best of State Commercial Design. New western Sydney performing arts centre Sydney Coliseum Theatre, at Rooty Hill retail, dining and entertainment precinct West HQ, was awarded the prize for best public design.

Adelaide’s natural wine bar Leigh Street Wine Room received the Best of State Commercial Design award, as well as a commendation in the Hospitality Design category.

The design by local firm Studio -Gram transformed a longstanding city drycleaner into a cosy drinking den with a newly built mezzanine, terrazzo bar and floor, exposed acoustic wall panelling, and – the pièce de résistance – a striking, lofty archway that runs the length of the room.

Fellow Adelaide architects Sans-Arc Studio also received a Best of State award – for residential design – for its gorgeous extension of a Torrensville maisonette. The cool and colourful renovation is defined by pink terrazzo, archways, and a plaster-clad exterior, which earned it the name “Plaster Fun House”.
