About 420 George Street

Located in Sydney’s retail district, listed heritage buildings abut the site on both street frontages creating the challenge of inserting a large scale mixed-use building incorporating retail and commercial space seamlessly into the fabric of the context. The retail podium is a modern insertion into the streetscape that references its historic neighbors. The façades, through an abstract composition of vertical masonry and glass blades, reinterpret the scale and rhythm of adjoining heritage buildings in a contemporary architectural language.

The building core has been placed on the north to reduce solar heat gain to the floor plate, while sunshades on the short east and west façades provide this protection. This combination of strategies has allowed the building to be conditioned by a hybrid low temperature VAV system with perimeter chilled beams. An eight-story naturally ventilated atrium in the low-rise portion of the tower creates light filled, vertically-connected floor plates, where there would otherwise have only been low value floor space.
