Donation Albers-Honegger Espace de l’Art Concret

The new museum for the Espace de l’Art Concret (EAC) was built on the occasion of the donation of the Albers-Honegger Art Collection, parts of which had been displayed since the 1990s on a rotational basis in the castle of Mouans-Sartoux. The castle rooms will mainly be used for temporary exhibitions in the future. The new museum is the second freestanding annex on the castle grounds, following a children’s painting studio called the Espace Art, Recherche, Imagination designed by architect Marc Barani. A third small building, the Préau des Enfants, was erected shortly after the museum. Both are set in a steeply sloping wooded area within the surrounding park.

The museum building’s minimal, square-shaped ground plan and its tower-like structure with cantilevered elements made it possible to insert it into the wooded site with as little disruption to the existing trees as possible. Its position on a slope enables ground-level access at various building levels. A projecting section forms both the entrance to the museum and a bridge to the path outside. The access area for the public conference space and for deliveries also projects from the main volume of the building.

The museum entrance is elevated half a story above the first exhibition level. The galleries, connected by open stairs, are arranged at half-story level and form a spiral tour through the building. Two closed, sky-lit staircases serve as escape routes and also offer visitors a short path back to the entrance after finishing their tour. In addition to the lift, these staircases form an interior vertical connection between the conference space and the other rooms on the lower levels.

The arrangement of the galleries along the façades, the lateral lighting via the windows, and particularly the proportions of the spaces recall those of a large home rather than resembling a classic museum. Although the windows do not provide the even illumination often thought desirable in galleries, this solution meets the express wishes of the donors, who wanted natural light that would enable the works of art to engage in a vivid dialogue with the world outside and to be seen under a variety of lighting conditions. The windows are placed at differing heights in the galleries. Double-paned and resembling box-type windows, the outer pane of glass is affixed to the exterior of the façade to offer primary protection from wind and rain, while the inner pane, which can be opened, provides thermal insulation. Between the two windows, and thus shielded from the weather, fabric blinds afford protection from the sun. The blinds can be closed if desired, transforming the windows into sources of pure light, like glowing panels.

The building is constructed of poured concrete, which is painted a light yellowgreen, in anticipation of the moss and algae that the nearby trees will eventually cause to cover it. Intriguingly, this color generates two diametrically opposed effects. On the one hand, it glows in contrast to the surroundings; on the other, it forms a harmonious background for the changing colors of the trees.

The donors’ commitment to art education is expressed again in the nearby Préau des Enfants, an open concrete structure in the forest where the children’s drawings and painting studies are exhibited.

New Building Kantonsschule Rotkreuz

Due to its central location directly at Rotkreuz railway station, the Kantonsschule Rotkreuz becomes a key meeting place. Together with the developments at Bahnhof Süd, the Dorfmatt Centre, and Lucerne University of Applied Sciences and Arts, it strengthens and consolidates the town centre of Rotkreuz.
The building responds volumetrically with a head and a wing; its head to the centre of Rotkreuz, and its wing to the neighbouring sports facility. A generous forecourt extends around the building, creating a transition to the sports grounds and the school’s outdoor areas to the east. An external staircase leading to a large rooftop terrace and landscaped pergola further expands this outdoor space. Along the west and south façade, arcades mediate between the interior and exterior spaces.
The new building for 44 school classes provides flexibly adaptable rooms and open areas for the implementation of new cooperative and interdisciplinary learning methods. The head contains the public spaces, such as the auditorium, media library, and the four-part sports hall, while the wing accommodates the general teaching classrooms.
The school building is characterized by a large public atrium in the head and several smaller atria in the wing, around which the individual learning clusters are arranged. The timber-hybrid construction remains visible and defines the character of the interior spaces.
The façades are equipped with photovoltaic elements on three sides, while the north façade integrates vertical greenery formed by climbing plants rooted in the ground.

Location Risch-Rotkreuz

Programme Cantonal school for 880 students in 44 classes.
Six- to eight-storey new building with class and subject rooms, auditorium, cafeteria, common areas, information centre with media library, staff rooms, and a triple and single gymnasium on the top floor.

Werkstadt Zürich Building X

Over the next few years, an important working location called ‘Werkstadt Zürich’ will emerge on the site of the SBB Werkstätten on Hohlstrasse next to the Duttweiler bridge. Here, historic industrial buildings that foster a sense of identity will be joined by new buildings and public uses in the outdoor spaces. With a target of 5 kg CO2-eq per m² (energy reference area), ambitious standards are being set for the construction of the new Building X in terms of sustainability.

The oblong, seven-storey volume with the northern cantilever is located on Hohlstrasse in a privileged urban location. As the first new development, Building X is intended to showcase the transformation of the site from the SBB Werkstätten into a ‘Werkstadt’ with urban production, creative business and a cultural scene. This is achieved through a mixture of diverse uses and a comprehensive utilisation of reuse materials, which relates to the history of the site and creates a specific aesthetic of sustainability.

The ground floor with commercial units aimed at the public and a freely accessible first floor, the so-called ‘Stadtgeschoss’ with a neighbourhood centre, crèche and library, form the base, which faces the neighbourhood on Hohlstrasse and the site on Hohlgasse. The 2nd to 5th floors contain two-storey commercial units with galleries, to be used according to the specific needs of the tenants. The building is topped off by a semi-public storey with a cafeteria, co-working areas and a small roof terrace.

Two entrances from Hohlstrasse lead to the two building cores, which provide vertical access. In addition, an external, single-flight staircase along the south façade takes visitors directly to the balcony of the ‘Stadtgeschoss’. The roof, which is angled out of the façade, highlights the public entry and at the same time offers both a pleasant ambience and protection. On the north side, the cantilever responds to the Hohlgasse within the site and forms a covered delivery zone. This side has an industrial character, whereas the outdoor area on Hohlstrasse conveys an inviting atmosphere with a variety of ground surfaces, seating and green areas.

Reclaimed rails, steel profiles, corrugated fibre cement panels, reused windows, stairs, gratings and railings characterise the elevations of the building. History and time are present everywhere in the weathering and wear marks of the materials. The strategy of patina is continued and the building is firmly anchored at the location of the former SBB Werkstätten. Building X makes a contribution to the iconographic potential of repurposed components, creating an architecture that uses resources consciously during construction and operation, with optimised CO2 emissions and low consumption of grey energy.

Schauspielhaus Pfauen Zürich, Remodelling and Complete Refurbishment

Der Wettbewerb umfasst den Umbau und die Gesamtinstandsetzung des denkmalgeschützten Schauspielhaus Pfauen in Zürich. Ziel sind der Erhalt und die Wiederherstellung der räumlichen Wirkung des historischen «Pfauen-Saal». Bestehende technische Aufbauten an der Brüstung des Rangs werden entfernt. Die Raumakustik und die Sichtverhältnisse werden für ein gleichwertigeres Zuschauererlebnis mittels gezielter Eingriffe verbessert: Absenkung der Bühne und des Parketts, eine neue komfortablere Bestuhlung und Reduzierung der Anzahl Sitzplätze von 750 auf 600 (inkl. 6 Rollstuhlplätze), Platzierung der Regiekabine im Rang sowie die Einführung einer mittleren Beleuchtungsebene.

Gewünscht war zudem ein neues Foyer, das zwischen der geschützten Steinfassade des Heimplatz und dem Saal vermittelt und zum Aufenthalt anregt. Das konzipierte «Foyer Publique» ist Teil des öffentlichen Lebens und, über den Tag verteilt, mit unterschiedlichem Programm bespielbar: tagsüber als niederschwelliger Aufenthaltsbereich (z.B. für die Studierenden/ Schülerinnen der Umgebung), Co-Working-Space sowie für Veranstaltungen (Workshops, Lesungen) und abends als festlicher Raum mit mobilen Garderoben und Snackbars für Stückeinführungen und Premierenfeiern. Das Foyer bildet als leichter Stahlbau einen Kontrast zur massiven Konstruktion des Bestandes aus Haustein. Dank des hohen Luftraums über der geschwungenen Galerie im Obergeschoss, die den Saal referenziert, gewinnt das Foyer an Grosszügigkeit. Die Vorhänge übernehmen die Rolle eines Bühnenbildes und können im Tagesverlauf immer wieder neue Szenerien erzeugen und von den wechselnden Intendanzen bespielt werden.

In den Randzonen um das Foyer sind flexibel unterteilbare Veranstaltungsräume, ein Bistro, eine Kantine und die Gastroküche angeordnet. In den oberen Geschossen finden Büros, Verwaltungsräume und Sitzungszimmer Platz. Beidseitig des Saals liegen die artistischen Bereiche des Theaters (Werkstätten, Garderoben, Maske, Aufenthaltsräume, Wohnungen), der technische Bereich (Ton, Licht, Regie) sowie die Haustechnik, Lager und Logistik.

Die Aktivitäten des Schauspielhauses sind nach aussen hin ablesbar und erhöhen die Präsenz zur Stadt. Die bestehende innere Tragstruktur des Gebäudes bleibt erhalten. Davor wird zum Zeltweg eine neue gläserne Hülle mit gerafftem Sonnenschutz gehängt. Die Storen referenzieren die Vorhangelemente des Theatersaals. Zum Heimplatz empfängt eine doppelgeschossige Stadtloggia die Besucherinnen. Zudem wird die historische Fassade mit digitalen Ankündigungen überlagert. Tagsüber informieren drei Screens oberhalb der Arkade über kommende Veranstaltungen. Am Abend weisen grosse Fassadenprojektionen auf die Theatervorführungen hin. Diese können mit den «Tastenden Lichtern» von Pipilotti Rist kombiniert werden und schaffen so eine Verbindung zum Platz.
