Behind 8,000 Doors: Inside Three Standout Architectural Projects

14 individual brands and two subsidiaries are represented under the Swiss brand Arbonia. Although the brand, which is now making its long-overdue public debut, maybe new, the list of realized projects certainly is not. A glance at the reference archive, which Arbonia presents prominently, shows this. These include construction projects for the healthcare sector as well as offices and administration, historical buildings, educational institutions, hospitality and residential developments. Three particular distinct highlights stand out, as they uniquely embody Arbonia's motto: 'open to aspiration'.

The mixed-use project The Circle at Zurich Airport, designed by Japanese architect Riken Yamamoto, features 8,000 doors supplied by Arbonia, leveraging the expertise of two of its brands.

The mixed-use project The Circle at Zurich Airport, designed by Japanese architect Riken Yamamoto, features 8,000 doors supplied by Arbonia, leveraging the expertise of two of its brands.

One prominent example is the mixed-use project, The Circle, which offers 180,000 m2 of usable space, situated at Zurich Airport. This includes two hotels with an adjoining congress centre, a healthcare centre, offices, shops and restaurants, an educational centre and more. The new construction was designed by Japanese architect Riken Yamamoto, who was honored with the Pritzker Prize last year.

With impressive reference projects such as the Technische Hochschule Ulm, the 14 individual brands and two subsidiaries under the Swiss brand Arbonia pool their expertise.

Arbonia supplied a total of 8,000 doors, drawing on the expertise and offerings of its two brands RWD Schlatter and Joro Türen. These doors met a wide range of requirements in terms of fire protection, sound insulation, access control, representation, materials and appearance.

Representation, structure and fire protection

For the Musée des Beaux-Arts in Lausanne, designed by Barozzi Veiga in an almost sacred concrete aesthetic and realized locally by Fruehauf, Henry & Viladoms, RWD Schlatter supplied technically sophisticated fire-protection doors in special dimensions, flush-mounted wooden doors and soundproofing elements made of wood. They provide the museum with representation, structure and fire protection.

With doors from PRÜM, Arbonia contributed to the Hotel Villa Toskana in Leimen near Heidelberg. The task here was to emphasize the Tuscan flair of the spaces, including through the doors. To achieve this, white-lacquered doors from the Modena series were installed, providing high sound insulation and Climate Class 3. They were also equipped with concealed Tectus hinges and an on-site Häfele hotel locking system.
