Introduction

The development of One40 William Street, Perth is an excellent example of mixed-use and transit oriented development. The office, retail and entertainment land uses are supported by pedestrians accessing Perth's Underground Train Station directly below the building.

Description of project

One40 William is a landmark commercial development in the Perth CBD. The contemporary, 19 storey tower and three heritage buildings comprise approximately 43,600m2 of floor space and accommodate around 2,500 workers. Approximately 36,000m2 is set aside for office space, accommodating a number of different government agencies. An area of 36,000m2 is set aside for shared facilities including a reception area, public interface areas, a data centre, meeting rooms and conference facilities. 7,600m2 of retail, food and entertainment tenancies are open to the public. This mix of land uses is strategically located above the Perth Underground Train Station and provides convenient access to public transport options, establishing a focal point for the City’s transport hub. 

The land use mix is supported by a number of other design features that contribute to an active community.

Movement networks

  • One40 William has frontages to Wellington Street, William Street and the Murray Street Mall. The building is centrally located to rail, bicycle and bus networks, providing exceptional access for workers and visitors. The significant permeability of the development enables pedestrian flow and movement.
  • All areas of the One40 William development are linked horizontally and vertically, both visually and physically, by laneways, courtyards, elevated walkways and vertical transport systems. General public access is available 24/7 to ground level laneways and squares.

Internal design

  • The building design is sustainable and exceeds the standards set in the Government Accommodation policy. In addition to sustainability excellence, the One40 William development has specifically supported workplaces that have access to natural light, working ‘community hubs’, shared open space areas and ability to co-locate working groups.

Streetscape

  • Active frontages have facades designed to be protected by fixed horizontal and vertical sunshades ensuring a passive solar response. Safe high quality pedestrian connections link the train stations, Forrest Place, Murray Street Mall, Wellington and William Streets to existing and new buildings.
  • The restoration of the Wellington Precinct buildings and the reinstatement of the Mitchell Building façade will restore these buildings to a recognised heritage standard and positively contribute to a local sense of place. The design of the building preserves the historic building fabric and encourages access to major street frontages and the pedestrian mall.

Permeable building design

  • One40 William has a highly accessible ground plan at 42% of the total site area, comprised of integrated pedestrian lanes, courtyards and squares. Some 17% of the public open space is open to the sky.  External open spaces within the tower include landscaped wintergardens, which provide an active ‘external’ space, which can be utilised by office staff.

Values

The mix of land uses at One40 William has a number of health, economic, environmental, social and use benefits.

Health value
  • Environmentally Sustainable Development (ESD) initiatives such as indoor air quality and access to natural light are important to the health and productivity of the occupants of the building. In 1984, a World Health Organization Committee report suggested that up to 30% of new and refurbished buildings worldwide are the subjects of complaints relating to indoor air quality. ESD principles suggest that generally indoor spaces should; specify that furniture does not give off VOC emissions, be designed for longevity, use renewable or recycled materials, use water-based paints, provide recycle bins, include recycling storage, provide task lighting and individual control of airflow. The new workplace at One40 William incorporates award winning ESD initiatives and provides a new benchmark for Western Australia State Government office accommodation.
  • Offices in One40 William have access to roof terraces for staff to enjoy outdoor spaces at upper levels, views of the Perth CBD and ‘fresh air’. Office workers within One40 William have convenient access to public transport with the central Perth Underground Train Station directly below the building.

Economic value
  • The One40 William development demonstrates a significant economic uplift from the former single level, ‘low-end’ retail and commercial buildings on the site. Approximately 2,500 workers now inhabit the office floors of One40 William, which is also home to fashion, services, food and beverage, and nightlife activities.
  • The City of Perth has demonstrated commitment to the creative industries through support for a number of pop-up projects. A Fair Trade Pop-up Shop was launched in the CBD for 10 days in May 2012, a joint initiative of Oxfam Western Australia, Students in Free Enterprise and the Western Australian Fair Trade Collective. The One40 William Pop-up Project encouraged new customers to the area.
Environmental value
  • One40 William received the BPN Sustainability Award - Public Building and Urban Design. The Sustainability Awards have been running for six years and recognise excellence in sustainable building practice in Australia. 
  • One40 William is the largest building to achieve a 5-Star Green Star Office Design rating, and is targeting a 5-Star Green Star Office As-Built rating.
  • The Property Council of Australia indicates that One40 William, is an 'A' Grade Premium Services building, incorporating a number of environmental initiatives. One40 William includes the most recent design, with destination lifts, high performance glazing and grey water treatment plant, all of which reduce operating costs and support sustainable outcomes. 
Social value
  • On Wellington Street, One40 William incorporates the Wellington Building, the original Globe Hotel and the Baird Building, along with the facade of the Mitchell Building on William Street, supporting a strong sense of place.
Use value
  • Based on progressive responses to workplace design, public realm, climate and existing conditions, the building has been designed from the inside out with the aim of engaging people who work within, visit or simply pass by. Both celebrating and mitigating Perth's specific microclimate, the building takes best advantage of light and shade. Its orientation allows maximum daylight penetration into the work environment and incorporates extensive landscaped rooftop spaces and winter gardens.
  • In 2011, One40 William won the John Septimus Roe Award for Urban Design for the government office fit-out, the Ross Chisholm award for Commercial Architecture and the overall winning architectural project, George Temple Poole award, at the Western Australian awards for the Australian Institute of Architects.
