Replacement housing developments Roswiesen-/Winterthurerstrasse, Schwamendingen, 2021–2025

When planning replacement housing developments, the question remains: how can the density be increased without affecting the qualities of the outdoor space?

The existing settlement has the typical features of Schwamendingen garden city. Our project aims to preserve these features – and, of course, increase the density.

First and foremost, it is the large connecting outdoor space in the centre that is to be preserved. In its new form, it will become the spatial and social centre of the settlement. All building entrances, the community room and the large passageway to Winterthurerstrasse are connected to it.

 

 

It is also important to react to external factors. For example, the green corridor envisaged in the model is made possible and continued with a generous boundary distance to the settlement in the north. The sensitive transitions at the edges are designed with low buildings or staggered heights.

A new urban density is created in the northern area of the site and along Winterthurerstrasse,  with 7-storey buildings. Here, the houses are stepped towards the centre of the site and the green corridor in order to reduce shadows. In this way, the continued existence of the garden city is ensured despite the considerable building height.

The south-western area of the site is occupied by two smaller 5-storey buildings that form a gentle transition to the neighbourhood. Furthermore, the link to the surrounding settlements is created by connecting to the existing network of paths and by adopting the point housing pattern.

 

Im nördlichen Arealbereich und entlang der Winterthurerstrasse kündigen 7-geschossige Baukörper eine neue urbane Dichte an, wobei diese sich zur Arealmitte und zum Grünzug hin abstufen, auch um den Schattenwurf zu reduzieren. So wird trotz beträchtlicher Bauhöhe das Weiterbestehen der Gartenstadt gesichert.

Der südwestliche Arealbereich besetzen zwei kleinere 5-geschossige Volumen, welche einen sanften Übergang zur Nachbarschaft formulieren. Des Weiteren wird die Vernetzung zu den umliegenden Siedlungen über eine Anknüpfung an das bestehende Wegnetz und mit der Übernahme des Punkthausmusters hergestellt.
