Materials planned to be used for the transformation has a lot to do with building, with the nature. Making a contrast to the existing structure, to reveal the existing tectonic potentials is another focus.
Mapping out materials suitable for the transformation are based on the qualities for materials according to the question of recycling, the possibility to be age along the existing old structure, lightweight structure, and to study the inside outside effect. Using alternative energy as an tool in the design, is another approach, which could be interesting to apply.
