Sustainable Housing for Life Design Competition 2015

The Three By Tree modular house is designed to be fully self-sufficient, deconstructable and adaptable to life circumstances and needs of future owners. It combines ecological, social and economic sustainability to a holistic approach, but at the same time keeps the needs and lifestyle of each inhabitant at the fore-front of all considerations.

Three By Tree is a ‘system design’ providing the framework to create and adjust the inhabitant’s settings according to their personal needs, lifestyle and budget. It consists of three main parts and can be adapted to life circumstances and needs at any stage of life. It also can be multiplied vertically and horizontally to cater for various urban and rural situations.

The three main parts to Three By Tree are:

1. Frame – the main structure of the building offers access and supply or storage space. It is also a common space for community integration on the ground level (as connector to the community) where ideas and resources can be shared without imposing on the private areas of the house;

2. Envelope – the outer skin of the building creates a double PV ventilated façade harvesting the sun’s energy for electricity and heating. It gives the possibility to use one or more sides of the facade as vertical gardens; and

3. Core – 81m2 decks on individual levels consisting of nine 3×3 squares. The decks are the dynamic parts, which can be easily refitted and adjusted or adapted for the inhabitant’s needs without having to change the frame or envelope.
