Instead of dividing the different functions of the building - for both habitation and trades - into separate blocks, the various functions have been spread out horizontally. The apartments are placed at the top while the commercial programme unfolds at the base of the building. This way, the residents get the best views and enjoy the sunlight, while offices and retail which are usually generators of heat due to computer equipment and human traffic, enjoy the cool of the shade. The architects have designed a large, coherent scheme with immense differences in height, which allows views towards the Copenhagen Canal and Kalvebod Faelled’s protected open spaces.
