Harnessing a wild aesthetic: Hassett Park

Urban recreation and a heightened experience of the city’s dynamic environmental systems come together at Hassett Park by Jane Irwin Landscape Architecture.

Hassett Park is set within the public domain framework for the Campbell 5 precinct, part of a redevelopment of inner-city sites along Canberra’s Constitution Avenue.

When Hassett Park opened in 2015 it was championed for meeting the ACT government’s environmental, social and spatial objectives. Designed by Jane Irwin Landscape Architecture (JILA) as a public park within the larger prestige estate development of Campbell 5, it is the physical manifestation of public open space policy that has evolved in the ACT over more than a century. However, in the context of the COVID-19 lockdowns and their impacts on public life and social interactions, how can the design of the park be understood within this evolution?

Parks and gardens are embedded in the fabric of Canberra. They were listed as requirements in the 1911 design competition for the new federal capital city, and the winning design of the Griffins responded to the site’s topography of mountains, hills and valleys. The design provided public gardens, waterfront gardens, a “formal plaisance,” informal lakeside parks, connected park and garden frontages and “dark forested hills” as the termination of vistas.

Public open space was at the forefront of the Griffin plan. It would be a city in a landscape.

Hassett Park is framed on all sides by residential and mixed-use development, with street connections to the community’s key public domain facilities.

Two world wars and a depression confounded Canberra’s development until 1958 when the National Capital Development Commission (NCDC) was formed. Over the next 30 years, the NCDC transformed Canberra from a Garden City to a Bush Capital, a city of over 260,000 and a city in the landscape. When the organization was disbanded in 1988, the ACT emerged with a dual planning system, one that both protected Commonwealth interests and served the needs of the state. Today the territory’s population is rapidly approaching half a million, and the Bush Capital is undergoing major change.

Campbell 5 sits in a prominent location on the corner of Anzac Parade (which follows the Griffins’ “land axis” between the city’s Mount Ainslie and Capital Hill) and Constitution Avenue (the base of the Parliamentary Triangle). It had remained undeveloped since the construction of Anzac Parade in the 1960s, as an area of open grassland with some areas of contamination, a patch of sun moth habitat and edge plantings of

With the JILA team appointed in 2011, the project went through a rigorous process of site remediation, heritage assessment, hydraulic studies, public consultation and concept, then detail design. Hassett Park comprises two areas, both overlooked by apartments. A small square portion to the north, where the drainage line enters the site, is bounded by three existing streets. It is connected to a larger diamond-shaped area to the south-east with apartments and access streets wrapping around the western and southern sides. The new streets retain views to the memorials on Anzac Parade and the northern view to Mount Ainslie is protected.

The drainage system forms the park’s central focus. Entering the park at the northern end, water is carried along a garden swale beside a formal area of grass surrounded by mature deciduous trees, disappearing under a formal terrace to emerge as an ephemeral creek that snakes through the park to a large holding pond. The system introduces a wild aesthetic of grasslands and water to the site – an aesthetic that overflows with smells, sounds and textures that shift character and mood depending on the weather and season, and encourage close encounters. As JILA has written of the water management system, “it becomes part of daily movement, and part of the play experience. It heightens people’s awareness and passively educates users of the role of water in the environment in an immediate and delightful way.” The system has performed well during storm events, though a program of creek maintenance seems to be required.

The site’s rectilinear western terrace provides expansive views over the park along with places to sit in morning sun and afternoon shade. Steps and a small auditorium set in mown grass lead down to the creek and holding pond. The wide, curvilinear path that follows the line of the creek and is the main thoroughfare for pedestrians and cyclists offers many pause points, creek crossings, exercise stations and play areas that weave together urban recreation with a heightened experience of the site’s dynamic environmental systems.

A bridge, with tanks for park irrigation, crosses the holding pond and provides access to the area’s surrounding apartments, Constitution Avenue and the Lake Burley Griffin parklands. At the park’s southern end, another path splits to enclose a grove of narrow-leaved ash before exiting the site into the suburb. The formal grassed oval on the park’s eastern side is edged by the earlier plantings of Japanese elm and velvet ash, and paths through them of recycled brick give access to streets that provide limited parking.

Cycling and pedestrian paths within the park link to the wider transportation network and connect the existing suburban fabric of Campbell to Lake Burley Griffin.

Five years on from its construction, Hassett Park is coming into its own, as a well designed, high-quality public park much valued by the community. The park supports national capital values, links into and expands Canberra’s green space network, and provides a wide range of recreation and education opportunities, while adding value to adjacent apartments. The urban creek improves water quality, increases biodiversity and blends educational opportunities with moments of wonder. These attributes have been recognized in the various awards that the park has received.

During the period of lockdowns and social distancing restrictions, Hassett Park has provided a sanctuary for Campbell residents, especially apartment dwellers. It has offered spatial relief, and an enhanced experience of nature and culture where young and old can exercise, walk their dogs, ride their bikes and sit in the sun or shade to talk or read. Hassett Park, through its careful conception and implementation, is proving resilient to the challenges of COVID-19 and offers an evocative model for future urban park development.
