Maddison Architects expanded the footprint of an existing 1960s log cabin in Australia with a contemporary, angular extension constructed from timber and cast-concrete. Built into a slope and surrounded by coastal Moonah woodlands, Cabin 2 is a self-contained apartment that is visually distinct from the old structure. The project's folded roof and prefabricated skeletal frame evoke the region’s hilly topography and twisted, wind-swept Moonah trees.
The 110-square-meter holiday home extension was created to accommodate extended visits from family members and guests. Since Cabin 2 was designed as a separate unit from the existing cabin, the new self-contained structure comprises a bedroom and ensuite, a living space, kitchenette, concealed study, and outdoor deck space. Filled with natural daylight, the timber-clad interior is divided into two levels: the bedroom and ensuite are located at mezzanine levels, whereas the other indoor spaces are a few steps below on the ground floor.
The compact and visually striking building was also designed to minimize site impact. As a result, the structure largely conforms to the existing topography and features a partly sunken monolithic concrete plinth that, according to the architects, is “an attempt to emphasize a feeling of refuge and physical engagement with the site.” After construction, the architects revegetated the site with indigenous plantings to strengthen the site’s connection with nature. Rainwater is collected from the rooftop and reused in the garden.
