The study

From context to implementation.

Context

The study area sits between an active rail corridor and a canalised river. Decades of single-use zoning left large parcels in fragmented public ownership, serviced but unbuilt, while the surrounding blocks carry high residential densities with almost no public open space.

Opportunity

Bulk services in the area operate below design capacity. Consolidating publicly held parcels creates a contiguous development footprint large enough to justify the river rehabilitation that no single landowner could fund alone.

Vision

A district organised around a rehabilitated river edge: continuous public ground, mixed-tenure housing at transit-supportive density, and a work-and-make economy along the rail interface.

Masterplan

A 70 by 90 metre block grid re-establishes the historic street pattern and breaks the superblocks into developable plots. A continuous 40 metre river park forms the spine; a secondary green street connects it to the station. Density steps from eight storeys at the station to four at the residential edge.

Urban systems

Movement is structured on a two-tier hierarchy: a distributor loop carrying service and through traffic, and an internal network of slow, tree-lined streets with continuous active edges. All plots are within 400 metres of the park and 700 metres of the station.

Housing strategy

Approximately 2 400 units across social rental, institutional rental and sectional title, distributed across all phases rather than concentrated by tenure. Typologies range from three-storey walk-ups to eight-storey perimeter blocks.

Infrastructure

Existing bulk water and sewer capacity accommodates the first two phases. Phase three requires an upgraded sewer connection and a new substation. Stormwater is managed through the river park as an attenuation landscape rather than piped capacity.

Landscape

The river is de-canalised in two reaches to create wetland attenuation. Indigenous riparian planting, a continuous pedestrian route and three neighbourhood squares form the public open space system.

Economic impact

The framework models roughly 42 000 square metres of commercial and light-industrial floor space along the rail interface, retaining the existing informal trade and light manufacturing economies rather than displacing them.

Environmental impact

River rehabilitation improves downstream water quality and flood attenuation. Development is set outside the 1:100 year floodline. Embodied carbon is reduced by reusing existing bulk services and three structurally sound warehouse buildings.
