Upon the client's request regarding more diversity, we maintained the same basic anatomical composition of the houses, but grouped them into 3 groups. In almost a symbolic manner, these three groups are named as metal, stone, and wood houses, to suggest certain harmonious constellations. It will have the same concrete as structure and exterior finish, but used with three different color variations of light grey, black, and wood color accordingly. Formwork would vary to suggest varying material qualities: smooth for metal, gridded relief formwork to suggest roughness of stone, and finally actual wooden planks as lined formwork for wood.
