The design concept for OTW Stage 3 is for two, hybrid tower forms of 20 + 30 storeys that are seen in-the-round andmark Bennelong Parkway, the central courtyard and Bay Park. The project is the third and final stage of the OTW masterplan site, located at the quadrant site at the southern gateway to the Wentworth Point peninsular. Originally, an industrial precinct developed in the 1930s, the surrounding context has been transformed into a new residential neighbourhood which comprises new streets and public open spaces which constitute 37.5% of the total site area. The building form is a hybrid tower and street wall that interlock with the existing street wall at lower levels and introduce a vertical fluid expression to the tower form, by varying balconies on the east and west elevations while maintaining a simple repetitious apartment layout at each level.
The buildings to the park side on Amalfi Drive provide an appropriate scale to the large public park. The buildings are 4/5 and 6/8 storeys. The massing responds to the heights of Sorrento to the north, and does not overshadow the building to the south at the equinox, only catching the elevations to secondary windows at 2pm in the winter. The height to the outer edge on Bennelong Parkway reflects the edge condition, sitting on a prominent corner. As it is curved it is generally only viewed obliquely, and in part. The heights of all but the tower buildings are generally consistent with the Concept Plan. Modifications have been made as part of the Development Application process to improve to the central courtyard, by breaking the perimeter form to bring more light into the courtyard and to increase permeability. As a result, reductions here have been balanced with some additions along Amalfi Drive. The overall built form composition reflects the DCP intent for the site and consists of street defining, perimeter courtyard buildings, with one building set within the park. However, the block typology adopts the new emerging form typology of Wentworth Point of low/medium rise buildings and towers.
The project achieves modulation in height and detail to break-up the built form into disparate elements, as opposed to a continuous street wall. The built form is broken into elements, separated by openings which give clear visual and pedestrian permeability to the courtyards. The towers are clearly separated from the medium and lower rise elements. The base of the buildings include entry lobbies and individual unit entries to activate the street. All units have good views, taking advantage of vistas to the park, generous courtyards or wider precinct views. A roof terrace has been introduced at Level 10 which is available for all residents within the development. A sky-bridge above the through site way connects the two towers together. The development is designed to embrace ESD principles. The use of appropriate built form with multiple cores generating through apartments and many corner apartments generates 60% cross ventilation. The massing and orientation have been organised so as to provide good natural day lighting and solar access into the primary living spaces and external living areas.
