The Big Small House embodies “The Least House Necessary” philosophy, embracing client/architectcollaboration, and presenting a new model for sustainable tropical living that is grounded in successfulhistoric precedents. The brief called for an efficient, passively cooled family home in a tropical gardensetting, made of honest, affordable materials. A ground floor studio and bathroom were required toaccommodate varying mobility. There was also a desire for the house to perform as a gallery for theartist in the family. The design is purposefully two storeys, maximising area for the garden.
In section, the house reflects traditional Queenslanders with the upper floor overhanging the lower, layeringclimatic protection from roof to ground. The resulting undercroft becomes an internal verandah andliving space with fluid inside/outside connections. The surrounding landscape will become the outerfilter to the house, providing additional privacy screening and climatic control. The landscape ispredominantly native endemic and edible species, contributing to food security and the adjacentriparian corridor. Sustainability informed design decisions, from siting and climatic performance tomaterial selection. Materials included locally sourced plantation timbers, low VOC paints, raw blockworkfinishes and E0 cabinetwork.
There is a rainwater tank and connectivity for a future photovoltaic
system. The 238m² dwelling sits easily on the 612m² suburban lot, leaving more than 70% of the sitefor landscape and pool. Orientation and siting maximise passive climatic performance, capturingbreezes, and providing shaded living and garden spaces throughout the day. A central void andclerestory windows ventilate the spaces vertically, while the upstairs gallery and breezeway moves air throughout the length of the house. A level of craft was required in construction detailing to achieve theraw, clean aesthetic:
- single skin, translucent stair of Australian hardwood and polycarbonate sheeting;
- galvanised "fence" balustrade surrounding the void and stair;
- off-form concrete plinths onthe terrace, with cast in relief patterns from recycled pallets;
- clear finished stack bond blockworkwalls with crisp white mortar.
