The office building in Hammarby Sjöstad has a concrete façade in relief forming a protective wall against Hammarby allé. The façade is divided into angled facets that are alternated giving it a braided effect. The heavy façade and the heavy concrete structure give the office a thermal capacity that reduces energy consumption.

The façade divisions allow for a varied window placement, where each office module can have two windows at different heights. One that is placed higher up, which provides light without a glare, and one lower down which has a view. The remaining façades are curtain wall systems with transparent and opaque glass panels. A penthouse with a double glazed façade cantilevers towards Hammarby Fabriksväg.

The office has its main entrance from Lugnets allé from which one also reaches the gym on the ground floor.
