Another step in the urbanisation of Sydney Olympic Park’s town centre, Boomerang tower combines a 7-storey podium of retail, office and above ground parking with a rises 32 storeys residential tower. above Sydney Olympic Park, making a striking addition to the suburb’s burgeoning residential and commercial development. The towerproject delivers on the future vision for Olympic Boulevard of a 6-8 storey streetwall with slender towers above. Adding 239 apartments, 5 shops, two levels of new workplace, shared outdoor amenity, and above ground parking, the project sits respectfully within SOP’s high quality landscape and public domain—anchored by 425 hectares of designated parkland.d—and adds 239 apartments, 5 shopfronts, two levels of new workplace, shared outdoor amenity, and needed parking to Olympic Boulevard, a SOP main street.
The design approach reimagined the single-podium/twin-tower competition brief by splitting the podium with a diagonal through-site link aligned to the nearby State Sports Centre forecourt. North of the link, commercial and parking uses are combined into a single form, while south of the link, the tower sits above the podium parking and ground floor retail.
The northern podium synthesises the architectural expressions of carpark and office, using glazed lifts on the corner and a similar façade approach to visually supress the parking and give the impression of a 7-storey commercial building. Above the southern podium, the residential tower form elegantly reconciles the alignment of the through-site-link and the eastern boundary, providing 100% of apartments with 2 hours solar access in midwinter and panoramic views of Bicentennial Parklands, Homebush Bay and the Sydney CBD.
The zigzag podium façade combines alternating panels of terracotta baguettes with aluminium mesh for the carpark and vision glass for the office. Expressed precast concrete spandrels provide impact protection in the carpark and – with the terracotta infill - deliver a masonry podium inspired by the site’s former history as the NSW State Brickworks.
The tower façade echoes the same elements, with concrete-coloured slab edge covers and brightly coloured vertical fins providing solar protection to the apartment façade, which includes fixed glazing, awning windows, colourback glass and open setback balconies. At the top of the building, the fins extend upward by one level to form an open crown which conceals a penthouse apartment.
The site masterplan originally called for two towers set over a 104-metre podium—a design that would have created a monolithic presence on Olympic Boulevard, as well as eliminating prime views and optimum solar orientation from half the tower floors. Instead, Boomerang’s design divides the site via a through-site link to connect to existing public space and separate residential and commercial uses. Two workplace floors stacked on top of 4 levels of parking and groundfloor retail make up the north building, which is carved to make space for outdoor terraces and make way for natural light. The design also minimises visual bulk, making the development a good neighbour.
Apartments have been located in a single tower over the south end of the podium. Its boomerang form minimises wind downdraft and adds a unique geometry to SOP. Floor area on the southwest boundary was transferred to the top of the tower to create smaller floorplates and achieve optimal solar orientation and views for occupants. 100% of apartments achieve two hours solar access at midwinter, and many look out to the Bicentennial Parklands, Sydney skyline, greater Parramatta, Homebush Bay and the Parramatta River.
Like the commercial building, the tower is expressed as six stacked volumes separated by horizontal bands. The materials palette was inspired by the site’s history as the former NSW State Brickworks. Staggered aluminium fins in a range of terracotta colours span between expressed slab edges faced with either concrete or aluminium cladding. The fins and projecting slabs provide shading to a layer of fixed and operable glazing, colour-back glass and open, setback balconies. At the top of the building, the fins extend upward by one level to form an open crown which conceals the lift overrun.
Residents enter the tower via a curved frontdoorsculptural lobby that bringswhere the tower form comes to the ground. Most of the residential floors locate bedrooms at the façade line, and living spaces lead out to balconies, which also help shield from excessive sun. Corner apartments have glazed, operable wintergardens in place of balconies to minimise wind impact. Low-rise floors offer 1 and 2-bedroom apartments, while mid and high-rise floors offer a mix of 1, 2 and 3-bedroom apartments. 2 double-storey penthouses top the tower.
Green spaces are provided on the roof of both podiums. Above the office space, the northern podium provides a 2,000sqm communal open space. Connected to the tower by a bridge link, the garden includes 2 pavilions, and dense trees, flowers and greenery to break the wind and create an inviting space. The southern podium is Outdoor terraces on level 7 of the tower and level 9 of the commercial building provide diverse, green places where all building occupants can socialise and enjoy nature. Level 7 will beplanted with low-water, low maintenance species, providing a lush outlook from the . Level 9, connected to the tower via a footbridge, includes residential lift lobbies.
