A single-storey house with a curved green-grey façade of wide windows and screened polycarbonate ‘bubbles sits high above Kangaroo Bay in Lymington, Southern Tasmania. Uphill, the stand of protected Blue Gums (habitat of the endangered Swift Parrot) provided cues for the building form, the need for maximum solar gain, low window reflectivity and the colour palette.
The dense stand of Blue Gums to the west cut most of the late winter sun, so the house is designed for maximum solar gain. Another key aim throughout the house was to achieve maximum light penetration; the result was a lovely play of light through the house all day (and often at night). The stunning views to the east are the focus of deliberately sparse interior detailing. The sole female owner requested a low-maintenance building where she could easily entertain guests and shut off her living zone while they were staying. The building develops the architect’s existing practice of designing low-impact, narrow houses in which views can be seen ‘through’ as well as ‘from’. This client had seen another of the architect’s recent projects, which displays this principle, and that of aging-in-place and realised these attributes were essential in her final home. The entire shell is clad in a custom orb in a colour that reflects the landscape, Jasper. All windows are double-glazed, and 13 roof windows over the northwest spine have moderate ventilation and light. Low reflectivity glass (0-10% reflectivity) to all windows minimises Swift Parrot's impacts. Two LaserLite polycarbonate ‘bubbles’ function as conservatories, operable for venting in the summer and retaining warm air in the winter.
The owner had four requirements, and each has been achieved beyond her expectations; low maintenance, a space that allowed for aging-in-place, a building that sits ‘quietly’ in the landscape and one comprising two bedrooms and ‘magic’. The latter refers to the ability of the spaces to delight and the wonderful play of light – a ‘changing panorama of colours and clouds’. The inner living area is flanked by two ‘floating’ polycarbonate ‘bubbles’; one a protrusion of the long kitchen, the other a private sitting area. The owner spends her day in these translucent ‘spaces with a view’ – in the mornings with a coffee and, later in the day, with a book.
Above the house is a stand of very old and protected blue gums. The form of the house reflects several of the felled logs in this stand – roughly tubular, grey-green, burled at various points and now wedged into the slope. In turning its back to the west, the house’s log-like form required a simple cutting into the slope. The view up to the house from the road reveals a low, green-grey building that replicates the pitch of the slope. When endemic grasses and low shrubs grow, the built form (and the driveway) will disappear completely. The house's interior and exterior colours are found in the stand of gums.
