The base idea is to separate the house into simple components, so different techniques can be used for each of them, turning the house completely material-independent. This way several bioconstruction options can be studied and used, depending on the local availability, without compromising the whole project.
The project also tries to achieve adequate bioclimatic behaviour and provide the best possible natural airflow, and tends to offer, inside a very simple space, a complex array of uses and grouping, by playing with lots of different levels and blurring the interior/exterior relationships.
