PROGRAM: School Renovation + Addition

DATE: 2024

TEAM: Pearchitectures

TECHNIQUE: Reuse

PLACE: Lullier, SWITZERLAND

THE RING AS A NEW SPATIAL ORGANIZATION:

The project integrates into the existing site, which consists mainly of isolated and linear elements (heads and limbs). It introduces a ring structure that completes the overall layout. This continuous form reshapes the existing circulation, which was previously made up of dead-end directional spaces. The ring formally and functionally connects the two main focal points of the historic composition: the administrative center and the conference hall. By creating a visual enclosure, it forms a courtyard—a symbol of gathering—within a multipolar project that houses two distinct entities: one facing southwest toward the Jura, and the other northeast toward the Alps, set within a hilly landscape.

VOLUMETRY:

The project is carefully integrated among the trees that need to be preserved, continuing the volumetric alignment of the existing building. The current walkway, located under the generous roof of the main structure, is extended by a minimal volume that wraps around a majestic cedar tree, which remains in place. This tree becomes the central pivot around which the new composition is organized.

Slightly elevated, the second building volume connects to the library, which is positioned beneath the base. The new structures do not overshadow the greenhouse nestled within the conference building. This minimizes the visual impact and allows the extension to blend lightly into the horizontal landscape composition of the original design by Damay and Frey.

This compact approach keeps the southern part of the site completely open. Views from the boarding school toward the eastern mountains remain unobstructed. This open space offers flexibility, inviting new uses, landscape experiments, or future projects.

REUSE AND RECYCLING:

The project includes dismantling two prefabricated buildings, which were originally meant to be temporary but have remained longer than expected. However, these prefabricated elements provide valuable materials that can be reused in the new building. Instead of sending materials and equipment to landfill, we aim to repurpose them on-site or elsewhere. Fixtures such as sinks and sanitary units can be refurbished and reused, while suspended ceilings may be repurposed as partitions.

The prefabricated buildings will be carefully deconstructed to sort their components. The structure and flooring will be preserved and serve as the foundation for the new building, reorganized to accommodate its intended functions.
