The division down the centre of the structure and the angular halving of the geometry of the floor plans lends the building a rhythmic structure as well as different levels of illumination. Each of the two cores features a helix stair- case arrangement and two lifts that provide access to two units on each floor. The apartments at each end of the building are organised around a large living area that extends the entire depth of the building and opens onto a total of four bedrooms. Two of these have en-suite bathrooms; a further bathroom is located in a freestanding box in the centre of the large space. Where the two halves meet at the corner, the basic principle of the apart-ment typology varies. Here, there is no large, continuous living area, and one bedroom less. There are no loggias or balconies. The excellent illumination strategy gives the façade a regular grid with only a few toilets located in the interior of the building.
