In an attempt to preserve the surrounding nature, the footprint of the building remained untouched. This new phase inspired itself from the natural growth of trees. The link of the tree/house to the soil remains the same while growing vertically and developing an aerial volume reminiscent of tree canopies. La Colombière’s vertiginous interior is a space painted all in white. Materials and structure of the previous phase are kept and uninterrupted so that the addition acts as an extension rather than an insertion.
