Elementary school in Sassenburg: A sustainable new building complements the existing building and creates modern learning and open spaces.
The new building carefully complements the existing elementary school, creates clear open spaces and connects the old and new buildings into a harmonious unit through a transparent intermediate building.
Project data
The open spaces are structured along an axis parallel to the new building and offer five different themed areas: Rest, play and activity, learning in green spaces, social encounters and a canteen courtyard for outdoor dining. The interior organization is centered around the canteen as the heart of the building, which creates an inviting atmosphere with variable room heights and targeted lighting and is directly connected to the old building via a central access axis. Administration and staff rooms are distributed in such a way that the original sense of space is retained, while larger and modern rooms are created.
The construction is based on a sustainable timber hybrid building with recycled concrete and prefabricated timber frames. Visible glulam ceilings with acoustic activation, colored slats on the façade and natural materials in the interior create a warm, high-quality and long-lasting atmosphere. Extensively greened roofs, triple-glazed wood-aluminium windows, water-permeable paved areas and natural outdoor facilities promote both energy efficiency and biodiversity.



The energy concept combines the existing combined heat and power plant with a photovoltaic system, supplemented by a ventilation system with heat recovery, which minimizes energy consumption. Passive thermal insulation is ensured by canopies, external blinds and cross ventilation. Comprehensive water management with retention roofs, retention boxes and near-natural infiltration areas stabilizes the water balance and supports climate adaptation. The result is a modern, sustainable and functional school building that optimally meets the needs of the school community.
