The local building regulation allows for a maximum building height of 23m, bringing the conception of a sunken first floor and allowing a higher floor to ceiling height. The green slope on the north side leads to the entrance of the building. Along with the lobby, these two elements act as a buffer from the entrance road. The 950mm slope helps to distinguish between public and private spaces. While on the South, the landscape level is raised by 1.2m to match the second floor. This allows the gym on the second floor to continue out to the swimming pool and landscape space.
