Project Information

28 Lily Street, Seddon

Private Family House



To create a three bedroom, sustainable, family home on an inner-city block (228 m2) with flexible spaces and maximum green space.

The orientation of this site defines the street entry and elevation to the South with the classic Northern backyard and it was decided to follow this while using the full width of the property.

Guiding the form and program was the need to simplify structure and reduce the use of steelwork for reasons of budget and embodied energy minimisation. The Planning constraints produce the side stepped form familiar to inner urban streets so the layout developed these structural lines through the planning of spaces. A balance was sought between the flexibility of use and the need for differentiated functions in the house, so the use of sliding walls gave a variety of possibilities in family living patterns. While the use of upper and lower floors are potentially interchangeable, the conventional lower living and upper kids play and sleeping spaces have been maintained so far….

Timber has been used for its ultimate sustainability and warmth throughout the external and internal spaces. Locally produced shiplap cladding has been oiled with a natural product which has proven durable in the exposed Western faces. Internally, almost all wall and ceiling surfaces are radiata structural plywood, again naturally oiled with a white pigment producing a cool and subtlely grained finish. A matte-ground concrete ground floor provides a robust and cooling platform in summer, with the small courtyard bringing in the garden to the central kitchen and living areas. In winter this glows faintly warm with the integral hydronic heating sourced from solar panels on the roof. 

Grey water from all basins and showers and laundry is fully recycled in the front garden via a reed bed to be reused together with all roof-collected rainwater in the toilet flushing and washing machine. Insulation has been maximised with a double-width timber frame and by planning service areas to flank the living areas as much as possible, the thermal performance of the house is optimised. While the original energy rating was at maximum 5 star, the current star rating is to be determined at 8+.
