Zephyr Group's Banksia to wrap new Kangaroo Point tower around 1880s Alpha Cottage

An 1880s timber cottage that has survived Kangaroo Point's transformation from riverside suburb to high-density apartment precinct is set to become the centrepiece of Zephyr Group's proposed Banksia development.

Rather than see the locally heritage-listed Alpha Cottage as an obstacle to navigate, plans integrate the landmark home into a new 18-storey residential tower, giving one of the suburb's oldest surviving residences a new role as the project's communal hub.

The development application covers a 1,177 sqm amalgamated site at 127-133 Lambert Street and 30 Shafston Avenue, where Zephyr Group plans to deliver 64 apartments above three basement levels. Designed by Joe Adsett Architects, the proposal carefully weaves the retained heritage cottage into a contemporary residential scheme, with the tower elevated above the historic building to preserve its presence within the Lambert Street streetscape.

Named after the native Australian Banksia flower, the project draws inspiration from its distinctive form through curved balconies, sculpted planter boxes and cascading subtropical landscaping that soften the building's profile.

As the design report explains: "The tower's identity is defined by its feature facade, drawing direct inspiration from the Banksia wildflower. The building departs from traditional rigidity through the use of elegant, GRC-moulded planter boxes that appear as if shaped by the breeze."

Plans propose 64 apartments, comprising 32 two-bedroom and 32 three-bedroom residences, across an 18-storey tower. Residents would have access to rooftop amenities including a swimming pool, spa, gym, sauna, private cinema, dining spaces and landscaped recreation areas, while more than half the site is dedicated to planting and open space.

The heritage component is the defining feature of the proposal. Constructed in the early 1880s and occupied from at least 1883, Alpha Cottage is recognised by Brisbane City Council as an important surviving example of Kangaroo Point's nineteenth-century residential development and as a representative transverse-gable timber cottage. Despite extensive redevelopment across the peninsula, the building has retained a high degree of its original form and internal fabric.

As part of the redevelopment, the cottage will be carefully relocated a short distance within its original allotment to facilitate construction before being returned to a prominent position along Lambert Street. Original verandah elements will be dismantled, catalogued and reinstated, while significant internal features, including timber flooring, wall linings, joinery, doors, windows and hardware, will be retained. Later additions, including the enclosed rear verandah, will be removed to better reveal the building's original form.

Once restored, Alpha Cottage will accommodate the building manager's office, mail room and parcel facilities, providing an active everyday use that supports its long-term conservation rather than preserving it as a static display. The heritage strategy also maintains landscaped space around the building, allowing it to remain visually distinct beneath the new tower.

The Heritage Impact Assessment concludes that "the proposal secures the ongoing occupation, maintenance and conservation of Alpha Cottage," finding the development would result in "no more than a minor impact on the cultural heritage significance" of the building while ensuring its long-term future.

Joe Adsett Architects have designed the tower to sit above the heritage building rather than overwhelm it, creating a clear visual separation between old and new. The development's flowing balconies, integrated planting and organic façade respond to Brisbane's subtropical climate while complementing the restored cottage below.

Banksia occupies a prominent corner in Kangaroo Point within walking distance of the Kangaroo Point Bridge, Brisbane River, ferry services, QUT, the CBD and the Woolloongabba precinct. The site also benefits from direct access to active transport infrastructure and sits within an area earmarked for continued higher-density residential growth.
