The International Grammar School Sydney designed by Allen Jack+Cottier is located in Ultimo, Australia. The recognisable form, colour and scale of the building was a direct response to the formidable collection of large brick warehouse buildings which give Ultimo its distinctive character. Allen Jack+Cottier exploited the plasticity, durability and transparency of glass in its scheme, using large, playful amoeba-like openings all over the 4-storey school’s external walls to lighten the facades, and provide multiple perspectives.
The building represents the second generation of ideas developed initially for the Berry Sports Hall, which won the best sports building in the World Architecture Festival in November 2009. Facilities include an undercover playground on the ground floor, a library, staff offices and an indoor multipurpose hall. The roof was designed to become an outdoor playground shaded by an array of photovoltaic cells.
