Futuristic residential buildings in the shape of a Christmas tree. At each branch there are luxury apartments with windows that culminate in a spherical balcony, formed by an upper glass semi-sphere and a lower structural semi-sphere, covered in "corten steel". The central parts of the buildings are made up of an octagonal structural column which gives solidity to all the various cantilevered floors, as well as containing the access routes to them. At the top of each building there is then, a glass and steel greenhouse in the shape of a pyramid. All in a mountain environment, at twilight, completely covered in snow with a typical Christmas atmosphere, full of lights and many red spheres on each floor and with the ski slopes illuminated in the background.
