The base and the top differ in architectural appearance, design, colour and use of materials. The building responds with different housing typologies to different urban conditions whilst the facade is comprised of an urban, lively and sturdy plinth that serves as a visual base for a lighter and more expressive top.
The existing colour palette of Amsterdamse Poort is translated into warmer but also striking shades of dark brown, gold and earth green. In terms of materialisation, one can think of brickwork, natural stone, aluminium, and frames, facades in wood, steel or aluminium. Compared to the base, the topping is lighter in terms of colour palette light gold tinted metal colours, which reflect light, are desirable when building in high densities. Lighter colours also reduce the impact of the high-rise on the surrounding streets. Green areas were designed on teh building not only in the form of accessible roofs gardens but also facade elements to encourage nature inclusiveness and suppressing external heat gain.
