The fluid nature of verandah space has been
integral to my research into houses for some time now. From this research two
distinct elements have emerged in my work – the (anti-tectonic) outer skin and
the ambiguous plan where use, function, inside and outside are organised in
accordance with the non dogmatic nature of verandah space as it exists in the
Australian context. The operable outer skin protects and shades, opens and
closes spaces to views and nurtures the occupants.
The house is positioned on top of a hill on a 40ha
site to take advantage of beautiful views to the distant ocean but the views
are to the west and the house is exposed to a powerful prevailing wind. In the
summer hot northerlies blow across the site and it is as a counterpoint to this
exposure that the house forms a ‘L’ shape and digs itself into the ground to
provide sheltered outdoor space for the occupants. Key functional spaces are
located discretely along the length of the plan and connected by covered
outdoor terraces rather than corridors. In Australia the verandah is
traditionally transformed in this way to make a sun room, a sleep out or a
place to eat in the cool of the evening.
To help the house to breathe there are slices through the east /west
spine wall so that air can move from south to north. The ground slab is
insulated, the windows are double glazed and the mullions are split to
eliminate thermal bridging, the spine wall structure is concrete filled masonry
to add thermal mass. Rainwater is harvested and stored in a 100,000 litre in
ground tank, sewerage is treated and used to irrigate the garden and an array
of solar collectors is located on a shed roof to the south west of the main
house. The floor is recycled black butt and the in-floor heating, run entirely
from tank water, reverses in summer to act as a heat sink to help cool the
house in summer.
