We see one of the key issues in Australian housing
being how we use the sun to improve new and existing houses. In this project we
made a very clear attempt to form a house around the idea of preserving light
into a garden space. As houses become (often unnecessarily) bigger and blocks
smaller, the available land for gardens is reduced. We have created a garden
that enjoys light all day – the form has cut from it the rays of the morning
sun to ensure light falls onto the growing area, one which the clients will use
for the growing of food.
This process is achieved by reverse shadow casting
– taking the area of space that is to have direct light and extruding it along
the different paths of the sun. This is then subtracted from the barn-like form
that is allowed under the planning controls, to the maximum height of 9m. The
surface created from this then becomes the external screen – and this acts as
both balustrading and sun screening to the deck and western façade.
Within is a open living space on ground level, two
bedrooms and bathrooms on the first floor and an occupiable attic space under
the ridge with views back to the city. The rear facade is a sustainable artificial timber
screen system used for sunshading, balustrading and view screening. The side
walling is treated like a roof.
The digital model was
used in the creation of the documentation drawings both in 2D and in 3D , and
during the construction stage, the digital model continued to be used to
further describe the geometry on site moving around the model on the laptop
screen. The digital model was unfolded using Tamasoft’s Pepakura origami
program and a physical card model was constructed. This was used with the
printed drawings and the laptop to ensure the builders and the sub-contractors
all understood the design and could set out the geometry with string lines.
