Church of the New Apostles diagonally constructing 'wings'

The New Apostolic Church extension in Lausanne, Switzerland, draws its design language from the inherent qualities of the existing building. The design follows a clear diagonal logic that structures the spatial organization and circulation while becoming its defining characteristic. The architects sought a way for the new building to honor and preserve the existing spatial concept while adding contemporary brightness and openness. The extension connects to the renewal of the existing structure, blending the old building's qualities with forward-looking vision. The existing ground-floor foyer is preserved and expanded. To maintain the spatial spirit of the original building, preserving the main circulation paths and the staircases at the building corners was essential; these staircases were restored and fitted with lighter, more transparent handrails. A new entrance is placed at the southwest corner. The generous new foyer provides clear views of activities within, welcoming community members into an open, lively space. The new form consists of two wings extending outward from the church's corners, expanding the ground-floor foyer toward the new entrance. One triangular wing incorporates the existing elevator and connects to the other wing's end, forming a new multi-purpose hall. This corner junction creates a covered plaza in front of the church, where the new entrance is located. The church appears as though lifted by wings, which form openings that welcome visitors. The architectural image symbolically expresses openness and flight, connecting earth and heaven. The facade was redesigned to meet current energy efficiency standards while providing optimal thermal comfort for occupants. The old facade has been replaced by an exposed concrete structure with light colors and materials, expressing direct, honest materiality to convey strong character. The project demonstrates how religious buildings can evolve while maintaining their spiritual identity, bridging tradition and contemporary architectural expression.
