Kreisschule Churwalden, completed by Atelier Peter Zumthor in 1983, extends a postwar school complex on a sloping alpine site in Graubunden through three stepped pavilions for classrooms and a gymnasium, transforming an addition into a measured sequence of terraces, porticoes, and pedagogical interiors.

Architecture has its own realm. It has a special physical relationship with life.

– Peter Zumthor

From Extension to Village-Like Ensemble

The Kreisschule Churwalden began as a school extension, but its architectural significance lies in the refusal to treat addition as attachment. The existing school, designed by Alfred Theus in 1958 to 1959, occupied the hillside as two volumes arranged in a T-shaped composition. Rather than continuing that geometry with a single compact block, Zumthor divided the new program into three separate buildings: two classroom pavilions and a wider gymnasium above them.

This decision shifted the project from object-making to settlement-making. The three pavilions climb the slope in measured increments, each one story higher than the last, forming a sequence of built volumes and outdoor rooms. The composition reads less as a subsidiary wing than as a small civic field, where the spaces between buildings carry as much architectural weight as the buildings themselves.

The strategy also establishes a careful relationship with the older school. The new structures do not mimic the rendered postwar buildings, yet they respond to their scale, roof pitch, and position on the terrain. Their reddish cement-block construction gives the extension a distinct material identity, while the stepped arrangement prevents it from overwhelming the earlier complex.

Topography, Movement, and Public Space

The site sits on the large debris cone of the Wititobel, where the ground rises steadily toward the mountain. Zumthor uses this gradient as the project’s ordering principle. The buildings are not placed on a level platform but are allowed to register the slope in their sections, producing a gradual ascent through terraces, stairs, and porticoes.

Each pavilion faces a break-time terrace, creating a sequence of exterior spaces that mediate between classroom life and the alpine landscape. These terraces are neither leftover yards nor purely functional access areas. They serve as thresholds, gathering places, and viewing platforms, linking the school’s daily routines to the topography of Churwalden.

Between the old and new buildings, a sheltered courtyard operates as shared ground. Its role is spatial and social: it connects different school levels, absorbs circulation, and frames the extension as part of a larger public setting. In this respect, the project extends the logic of the village rather than the logic of the institutional campus, treating education as a communal activity embedded in the life of the settlement.

Classroom Typology and Pedagogical Space

The two lower pavilions develop a compact but unusually layered classroom typology. Each is conceived as a two-storey unit for a single class, closer to a small house than to a corridor-based school block. This domestic analogy is not sentimental; it provides a spatial framework in which different modes of learning can coexist within one continuous volume.

On the lower level, group rooms accommodate music, drawing, craft, and other practical activities. These spaces are reached from a central corridor and are visually opened by glazed fronts. A timber-lined stair then rises to the main classroom beneath the roof, where the upper level expands into a gallery-like room connected back to the studio below. The relationship between levels is therefore visual, acoustic, and pedagogical.

The arrangement challenges the conventional separation between formal instruction and manual work. Rather than isolating the classroom from the workshop, Zumthor folds them into a single spatial unit, allowing making, discussion, study, and display to overlap. The result is a school plan in which the section serves as an educational instrument, not simply a technical solution for a sloping site.

Structure, Material, and Early Rationalism

The material palette is direct and restrained: reddish gray-brown cement block, fair-faced concrete, solid timber floors, and turquoise-painted metalwork. These materials are used without pictorial excess. Masonry establishes mass and texture, concrete defines lintels, columns, sills, and floor plates, timber introduces a tactile register underfoot, and the turquoise metal elements mark stairs, bracing, frames, and fittings with a consistent secondary rhythm.

The porticoes make the structural argument explicit. Massive square columns support kinked concrete lintels, above which shallow masonry flat arches span between supports. The detail is not applied to the decoration. A reinforced-concrete element absorbs the lateral thrust of the cement-block arch, allowing the construction to be read as a balance of forces. In this early work, structure is already treated as a carrier of architectural meaning.

The gymnasium intensifies this logic through its section. Its raised roof admits daylight through clerestory glazing, while timber trusses span longitudinally along the length of the hall rather than across it. This unusual orientation draws the eye through the room and gives the roof frame a civic presence without disguising its practical function. The space sits between the typological memory of a basilica and the plainness of an industrial shed, held together by exposed construction and calibrated light.
