Here is the first look at the new Silk Apartments in Pitt Street, Sydney. This DA for 70 units has been lodged with council. The unique design is a response to the solar conditions on the site. The shape of the building has been generated to maximise solar exposure to the surrounding buildings as well as to the units themselves. The buildig tapers towards the top to allow greater sun light and air to the ground. The shape is a result of exhaustive studies tracking shadow and solar conditions in the 3-D city model. As a result theunits willl enjoy maxmum amenity and the sinuous shape is an expression of this optimum condition.
