Community Center Rottenbach By atelier st | Sustainable Cultural Hub in Thuringian Forest, Germany

The Community Center in Rottenbach, designed by atelier st, is a thoughtfully crafted cultural building located on the edge of the Schwarzatal Valley in the Thuringian Forest, Germany. Nestled among rolling hills, historic villages, and slate-roofed structures, the center is adjacent to a renovated historic railway station, evoking the nostalgic charm of a model railway landscape while serving as a functional, modern community space.

Context and Concept

The project was conceived as a small replacement building for the local community, positioned within the eastern extension of the listed station ensemble. Supported by IBA Thüringen, the design seeks to blend simplicity, familiarity, and local identity while providing a neutral, public space accessible to residents. The architectural form, a straight, rectangular building with a pitched roof, draws inspiration from typical Thuringian Forest building types, maintaining harmony with the surrounding historic structures.

Spatial Organization

With a floor area of approximately 103 m², the center integrates toilets, kitchen, and a surprisingly spacious communal hall. The hall extends up to the roof and is fully clad in warm timber, creating an inviting and atmospheric interior. A transparent, barrier-free main entrance with an adjoining breezeway provides direct access opposite the station building, while the kitchen and storage area are positioned to the west and can be accessed independently. A wrap-around cantilevered roof allows for sheltered outdoor activities, enhancing the usability of the space year-round.

Materiality and Construction

The center’s design emphasizes clarity, simplicity, and durability. The structure rests on strip foundations with a reinforced concrete slab, while the main building is a timber construction. The uniform 1.25 m grid organizes both structural and aesthetic elements, visible inside and out through cover strips and cassettes. The rafter roof construction is expressed internally, with overlapping insulation and natural slate roofing referencing the traditional local architecture. The exterior is clad in color-coated timber panels with vertical profiles that provide protection against weather while evoking a subtle plasticity in form.

Inside, polished exposed concrete floors mixed with dark local sand complement the visible timber structure, which is protected with a clear coating to retain the natural material expression. Windows feature highly insulated timber frames with triple glazing, maintaining comfort and energy efficiency.

Sustainability and Energy Efficiency

The building’s compact, largely closed volume with a low A/V ratio ensures optimized energy performance. Large roof overhangs shade the minimal glazing, preventing overheating in summer. The choice of locally sourced timber reflects sustainability, while prefabricated construction elements enhance economic efficiency. Combined with wood-fibre insulation boards, heavy roof insulation, and triple-glazed windows, the design minimizes heating costs and ensures efficient energy use, with heat supplied via the adjacent station building.

Community Integration

The Community Center Rottenbach is a model of sustainable, contextually sensitive architecture. It successfully merges cultural heritage, material honesty, and contemporary design, providing a welcoming space for residents while respecting the historic railway station complex and Thuringian Forest vernacular.
