Urban Form Analysis - Type D Canberra Example - Weston, Weston Creek WESTON is located west of Canberra Central within Weston Creek. Weston Creek town centre was established in the late 1960s, with the then National Capital Development Commission describing Weston Creek as ‘one of the most picturesque parts of the National Capital’. Land Use Comparison Land Use Map Built Form v Open Space Weston Creek features a regular pattern of fi ne grain building footprints. The built form defi nes linear blocks of open space (roads and back yards). Green Space Weston Creek exemplifi es the 1960s approach to local landscape development, with buildings set in bushland. Native vegetation is continued throughout streetscapes and urban open spaces. Building Footprint - 14% Private Open Space - 40% Semi Public Open Space - 0% Road Verge - 12% Road - 9% Public Open Space (parkland) - 25% Weston Creek sits within a bushland setting which connects to adjacent ridges and buffers. Private Space v Public Space Private open space is provided to each dwelling. Generally consistent setbacks create uniform streetscapes and space at the front of dwellings, and larger areas of private open space behind. Building Height and Road Reserve Building heights are uniformly low rise (light grey). Road reserves also align with open space corridors.

A network of roads and dedicated cycle paths allows movement through the study area, although like Yerrabi the distances to other amenities such as shops and public transport are over 1km. SUMMARY High performance WESTON 400m radius 800m radius LYONS • A vast amount (70 per cent) of the urban area represents green open spaces with buildings set in bushland, large front setbacks and generous backyards. Low performance Comparative Snapshot People per ha Urban Area Land Take per Person (m 2 ) Public Open Space per Person (m 2 ) Road per Person (m 2 ) Water use per Person (kL) CO2 Emissions per Person (t per year) Low Income Households (%) Reid Kingston Gungahlin Weston Hannover Freiburg Dockside • Low population density with only 13 residents per hectare and with 800 m2 per person, nearly four times the land-take of Reid and Kingston. • The highest average building footprint per dwelling (270 m2). • With 6.4 tonnes per year the highest carbon emissions per resident from heating and cooling. • Highest potable water consumption per resident (111 kL per year) due to watering requirements of generous gardens. • Narrow housing choices with detached houses for medium to high income households only. • Aging population with 61 per cent of the population being 40 years and older.
