Project Description: 
Liberty Place is not a singular tower
 form but a rich interplay of three slender architectural forms inspired
 by the unique qualities of this wonderful Sydney city site. The 
development unites public, corporate and hospitality architecture into a
 cohesive environment. It is an amalgamation of five sites comprising 
of a Premium Grade forty-four storey commercial tower, a penthouse 
apartment, a heritage-listed building (Legion House) and a three storey 
office and retail building (167 Castlereagh street). Liberty Place 
occupies a prominent site in Sydney’s Central Business Districts, 
with dual frontages to 161 Castlereagh street and 242 Pitt street. 
Collectively, it is an articulate assemblage of elements (ground plane, 
street walls, tower elements and landscape). The architectural forms 
create a dynamic public space and reinvigorates a previously run down 
mid-city area.
ANZ tower with its distinctive sinuous form and striking glass-walled 
facade has seamlessly redefined the city skyline. The skyline of Sydney 
is an integral part of the city’s identity. The tower has become an 
iconic reference point, with a rooftop feature thats dramatically 
captures and breaks the light. This layered silvery tower gently turning
 towards the Harbour and terminating in an arch of louvres, makes a 
dramatic contribution to this great city skyline. 
The commercial tower provides 57,000sqm of Premium Grade NLA with 
efficient floor plates with access to outstanding views for occupants. 
ANZ Tower has achieved a 6 Star Green Star Design (Design V2) from the 
Green Building Council of Australia. Significant energy savings are 
achieved through the use of efficient light fittings, low temperature 
VAV air conditioning with perimeter active chilled beam technology. The 
building also features two gas fired cogeneration units to minimise its 
carbon footprint.
The base of the tower invites the energy of the city into the 
development, consisting of a retail and dining precinct, public open 
spaces, a sunlit plaza and pedestrian lane way connecting Castlereagh 
Street and Pitt Street. The light-filled pedestrian lane way provides a 
unique ground plane and entry into the commercial tower.
The Castlereagh street frontage features the heritage-listed building 
Legion House, originally constructed in 1902 by the YWCA and operated as
 a women’s hostel and outreach service for 60 years. Legion House is 
heritage listed and protected due to its social significance. 
Consideration of the site’s rich history led to the authentic 
juxtaposition of new and heritage elements. 
Restoring and redeveloping Legion House enhanced its overall utility and
 environmental performance. With a 6-Star Green Star- Office v3 Design 
rating, the six-storey ‘Autonomous Zero Carbon Life Cycle Building’ 
generates renewable electricity on site resulting in zero net carbon 
emissions. Receiving little sun or wind, Legion House receives its 
energy from a process called biomass gasification. This technology 
converts biomass (plant sourced) materials to a combustible gas that 
generates electricity. Whilst traditional gasification plants utilise 
standard wood chips or briquettes (made from compressed waste sawdust), 
Legion House can use the commercial paper waste generated from the 
adjacent office tower through shredding and compressing this waste to 
form paper briquettes (which can be used in the gasification plant). 
Essentially, this means Legion House creates its own renewable 
electricity on site resulting in zero net carbon emissions and is 
disconnected from the electricity grid with any surplus power created by
 its independent system (to be supplied to the storey commercial office 
tower on the site).
Legion House incorporates three retail tenancies to the ground floor, 
and has been extended with two new office floors and a western extension
 providing additional office space. The lift and stair case have been 
located external to the building in an elegantly detailed, curved glass 
enclosure to minimise the heritage impact while creating visual interest
 and a new laneway entry.
In addition to energy efficiency, Legion House has been designed to be 
water balanced. This means that in a year of typical Sydney rainfall, 
all the amenity and operational water needs of the building will be met 
through rain captured on the roof. This is achieved through the use of 
advanced water conservation technology, high efficiency fixtures, vacuum
 toilets and the use of high quality rainwater recycling.
Collectively, Liberty Place is not only celebrates the public domain, 
but embodies significant architectural and environmental innovation. The
 development successfully balances urbanism, heritage and sustainability
 considerations with commercial requirements to create a rich and 
considered architectural expression.
