WGE are providing full project support from concept design to construction administration across multiple disciplines for the 4-6 Bligh Street luxury hotel in Sydney.

The 55-story tower is the first luxury hotel to be built in Sydney in over 20 years and will include commercial and hotel space together with shops restaurants and cafés. The sky rise part of the building will house a rooftop restaurant, bar and garden with panoramic views of the Sydney Harbour.

The hotel will be operated by Andaz Hotels, Hyatt. The first three floors will include commercial retail spaces, as well as separate entries for both the hotel and commercial spaces. A commercial office podium, which includes a pool, wellness centre, childcare services and co-working facilities, will occupy nine floors above the retail space, and hotel rooms and suites occupying the remaining floors.

The building design went to a design competition after the Stage 1 DA which WGE participated to along side of architectural firm Woods Bagot.

The project has some extremely important sculptural aspects including the building form, façade mix between solid and glazing to drive sustainable outcomes. There is also an emphasis on landscape at the lower mid and high levels with the roof top area, including a large living tree and vertical voids with hanging greenery.

The building will set two new environmental and planning standards for the city and is the first hotel to achieve a WELL Building Standard—the leading global rating system exclusively focused on how buildings affect end users’ comfort, as well as the City of Sydney’s Central Sydney Planning Strategy.

WGE developed key service engineering strategies to manage the mixed-use ownership structure of the hotel within a very tight floor plate, whilst providing centralised plant options and metering solutions to meet both regulatory and operational requirements. We are also driving innovative solutions relating to existing building noise, ventilation and open areas, to minimise impacts of the services for the new tower and to maximise floor plates through minimising large vertical risers.
