Terrace Tower - Apartment Floor Plan

In Manhattan, strong urban growth meets limited space. For decades, the logical consequence was an unstoppable expansion upwards towards the sky. Recent developments show that in the future, even higher buildings will be created on even smaller plots. This was the starting point for this project.

The Terrace Tower wants to counteract against two of the biggest deficits in the residential culture of Manhattan: The lacks of personal open space and individuality. The building is shaped as a simple, thin cuboid with rectangular outer spaces cut out of it. These irregularly distributed holes define the order of the floor plans and as a result create a multitude of different apartment types, also varying in their sizes. As a terrace, they enrich the living space and offer a reference to the exterior. Via these introverted loggias as well as via the windows covered by an exterior pane, the apartments can be ventilated naturally despite high wind speeds making unecological air conditioning systems unnecessary.

The light fibre cement facade integrates with the typical stone materialities of New York City. Adding wood to it in the loggias gives a garden-like atmosphere. Going up the building, more loggias are found toward the top. On one hand, this creates more outer space in the higher, bigger apartments; on the other hand, it reflects the statics' requirements to the bracing exterior wall made of solid reinforced concrete, which is part of a tube-in-tube-system. The beams, necessary on every floor for coupling the tubes, are lost in a raised floor, which also hides horizontal installation pipes and the thermal insulation in the loggias.

Bearing structure, installations, floor plans and loggias were not only optimised individually, but also coordinated with each other until they were connected symbiotically. The result is a forward-thinking, balanced edifice, which defines the outer appearance of a tower disappearing towards the sky.
