A key aspect of the project is its sustainability. The main day-lighting system is with sunlight: in addition to the natural daylight entering through the windows, the house has a fiber-optic system that introduces sunlight in the rest of the house, especially in the inner garden providing with the necessary natural light for the plants and trees. This garden provides the house with an outstanding natural ventilation and heating system. Trough special materials and an efficient window and shutter system the use of not renewable energy is minimised. In addition, the house is a digitalised space, not only because of its use of TV, DVD, and PC projectors but also because its surfaces are digitalised in terms of conceptualisation and information. The slopes, valleys and multi-height places are the appropriate ones to create a space were the individual desires of each family member are taken into account; and where communication, co-operation and binding among family members can harmoniously take place. As we enter the house by a mid level, we see an inner garden where, depending on the time, we can found the kitchen. It moves in this multiple height space, providing with the right environment for each situation. This is how the kitchen is in contact with all the spaces of the house an allows to whomever is there to share the activities of the other members of the family. Thus, the kitchen becomes a small cultural plaza, adapted not only to life but also to nature .
