Verdict in design competition for Zentrum Papiermühle in Ittigen

The municipality of Ittigen, Steiner Investment Foundation and Steiner AG jointly staged a design competition for the focal development site Zentrum Papiermühle. The jury unanimously recommends pursuing the proposals submitted by the team comprising architectural practice E2A Piet Eckert und Wim Eckert Architekten, landscape architect Studio Vulkan Landschaftsarchitektur and engineer Schnetzer Puskas Ingenieure.

Prelude to redevelopment at Papiermühle traffic hub
The Zentrum Papiermühle site is centrally located in the Papiermühle district of the municipality of Ittigen, close to the S-Bahn rapid transit station of the same name. The site fronts Worblentalstrasse and directly overlooks the road junction between Papiermühlestrasse, Grauholzstrasse and Worblentalstrasse.

An urban design solution for the site (use, development, infrastructure provision) was formulated as early as 2014. This then served as the basis for amendments to the planning instruments governing the site, i.e. the masterplan for the focal development site Ittigen-Papiermühle, zoning plan, planning regulations and associated development order. The design competition was staged as an authoritative procedure involving the municipal bodies for the procurement of a convincing local planning, architectural and functional solution for the site.

Five design teams comprising architects, landscape architects and structural engineers were invited to participate. The jury, chaired by Michael Geschwentner (Steib Gmür Geschwentner Kyburz partners plc architects & urban planners), evaluated the proposed schemes in relation to the goals set out in the competition brief plus numerous criteria including urban design, architecture, open spaces, infrastructure provision, styling, use, cost-effectiveness and sustainability. Particular importance was also given to compelling, high-quality apartment layouts.

Appraisal of winning scheme
In the jury's opinion, a notable merit of the proposals put forward by E2A Piet Eckert und Wim Eckert Architekten AG is the shrewd urban disposition that lends the location a strong identity with intriguing spatial qualities and the required degree of public access. The scheme was unanimously recommended for further development.

Starting from a precise analysis of the urban context, the architects develop a volumetric arrangement of high-rise and linear block with a well-proportioned surrounding precinct that responds to the prevailing topography and offers a prestigious address for commercial and residential occupancies.

The high-ceilinged ground floor lends the high-rise an assured presence while the interior adeptly echoes the site's split levels. The newly created precinct combines with the ground-floor premises to create a strong public focus capable of unlocking and energising the location. The linear block additionally benefits from the open space to the rear. The filigree high-rise exterior engages with the slender members of the timberwork linear block to establish a harmonious relationship between the two volumes.

The following five design teams (listed in alphabetical order) took part in the competition:

  • Armon Semadeni Architekten / METTLER Landschaftsarchitektur / Syntaxis AG (with Holzbaubüro Reusser GmbH as subsidiary company)
