The project is a residential tower for the Columbia University of New York. Located at the north-east corner of Morningside Park and saving an unevenness of 20 m high, this tower combines students, teachers and non-university people in the same development of 33 floors.

The twisting geometry of the tower respond to the park, trying to make a light building, achieved by the unusual external structure. It consists of a number of slender concrete sheer walls of different heights which support a series of stacked blocks that are able to rotate to allow available view. By this way walls are dug into the park leaving free space in all the spaces between.
The north façade is closed to the cold and the communications are located in there.
All dwellings are poised in the spaces between structure, students' ones are on 1st to 16th floor, teachers' ones on 17th to 28th floor and renting houses are on 29th to 33rd floor, enjoying of the dramatic views of New York city.

There are two entries, both of them takes to four-height common floors with resting and meeting places to stay. One of the entries is sited from Columbia University, two of the sheer walls makes the entry to the 5th floor, and the other one, is going up a little hillside from the park plane, arriving to first floor.
The tower has its own roots in the park creating sheltered resting places in the middle of the city.
