About Collins Arch

Designed in response to planning regulations seeking to limit shadows cast upon the Yarra River to the south, Collins Arch occupies a full 6,000 square meter city block in the center of Melbourne’s Central Business District. Composed as two buildings with linked floor plates flanking a large open void, the project had been planned as a mixed use concept, taking advantage of the central location which offers amenities and accessibility for a multitude of building functions. Within Collins Arch is 50,000 square meters of office space, a five-star hotel, retail, restaurants, over 200 luxury residential apartments and 2,000 square meters of civic space.

The building façade composition has an emphasis on articulation and texture, breaking down the scale of the building as it meets the street. The residential units of the upper floors feature a series of setbacks, providing occupants with outdoor terraces as the upper floors tapper towards the skybridge of connecting floor plates containing resident amenities. The base of the building was arranged around outdoor public space with focus on enhancing central Melbourne’s active streetscapes.
