Two duplex townhouses were proposed to replace an existing weatherboard house in a quiet, leafy suburban street in Camberwell. The brief asked for low-maintenance, energy efficient units with a point of difference and uniqueness. Having spent time in Japan, the owner’s appreciation for Japanese culture and architecture were strong drivers for the design aesthetic.
Some of the challenges we faced involved scale, to create generous four bedroom units with multiple bathrooms and living areas that would work in harmony with the surrounding environment and meet strict Council requirements. Introducing abundant natural light for the south-facing unit and maintaining a continuous ground floor level for wheelchair access were other key considerations.
Large skillion roofs with vast overhangs help break-down and express forms and provide shelter from the elements. Chain downpipes create a point of interest upon arrival and heighten sensory experience on rainy days. Large skylights throughout capture natural light and create a strong connection with the outdoors.
Traditional samurai armour provided inspiration for the design aesthetic of the materials palette, which was kept simple and consists of layers of more refined finishes such as rhinezinc, terracotta and timber cladding to highlight building forms.
Good solar orientation, thermal massing and robust, long-lasting materials are some of the sustainable principles that enhance the buildings' energy efficiency. ‘Terreal’ terracotta cladding acts as a breathable wall to help increase thermal performance, while high-level operble clerestory louvre windows allow for cross-flow ventilation and heat extraction in summer.
Hot water is supplied throughout via solar HWS units and rainwater is also harvested for re-use.
