The re-densification of districts offers the opportunity to make the city more tangible as a designed spatial continuum. The spatial dialogue of urban fragments turns the city and the district as a whole into an area of identification. The two sides of the perimeter are characterised by very different urban spaces, each with its own unique qualities. With the concentration of the building volume along the construction line at Letzigraben, the urban character of the streetscape is strengthened and Heiligfeld Park as the green centre of the district is extended up to the plot. The concave spreading of the volumes to the park side reacts to Steiner’s differentiated development and intensifies the orientation towards the park. In the dynamic context of open and enclosed urban spaces, the project seeks not only a balance between urbanity and greenery, but also between classification and independent identity.
