Sustainable urban design and architectural firm Harrison and White has designed the Foyn-Johanson Home in Northcote, Australia. The objective was to come up with a concept that would allow the sun’s rays to shine down inside the residence, specifically into the garden where the owner plants their own food.
Description by Harrison and White:
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 use for productive growing. 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 th e planning controls, to the maximum height of 9m. m. 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.
