Transforming Historic Churches into Vibrant Meeting Places

Church spaces are among the most influential spaces in public life - yet many remain empty today. Decreasing numbers of visitors and changing societal needs bring numerous sacred buildings to a turning point. Their reuse, therefore, presents planning with a special challenge: it demands responsibility, sensitivity, and new answers.

Sacred buildings often do not meet today's requirements for building services, fire protection, or accessibility. At the same time, they carry a deeply rooted religious-symbolic significance alongside their material value. Interventions are therefore not only evaluated structurally but also culturally and ethically – requiring a sensitive dialogue between the church, monument preservation, the public, and architecture.

The Power of Space
Precisely because sacred buildings possess extraordinary spatial qualities, they are particularly suitable for uses that actively make use of this generosity. Large spans, guidance of light, vertical spatial impact, and clear geometry give church spaces their special atmosphere. However, these very characteristics are sensitive to (technical) interventions. Change is only tolerable up to the point where spatial impact, proportion, and lighting concept remain discernible.

But which functions can enliven the space without overpowering it? Not every use fits in a church. Sports, cultural, or assembly uses work well because they can be organized independently. They allow the space to be experienced as a whole. The key is always that they can be implemented with justifiable, reversible interventions.

Adding instead of Competing
Dealing with the symbolic meaning of such spaces demands above all: restraint, readability, and dialogue. New uses must remain recognizable as contemporary additions and must not attempt to imitate or reshape the sacred expression. New functions can be integrated without competing with the existing architecture, by designing new elements constructively, clearly structured, and formally reduced. Freestanding, additive installations respect the existing structures and allow the historical architecture to remain influential.

Reversible or minimally invasive interventions are key. Because requirements and uses may change again in the future. Therefore, all interventions must be designed to be reversible and as conserving of the substance as possible. Reversibility creates both monument preservation acceptance and long-term flexibility.

Movement in the Existing Structure: Church as a Climbing Space
The parish church Petrus Canisius is a successful example of the development of a church space. The key to success lay in the Integrated Design from the beginning – in the interaction of architecture, building services, electrical planning, and structural engineering. Only through this approach a solution was able to be developed that considers the requirements of the church, the city, monument preservation, and the public equally.

In the church space, the spatial effect of the sacred building designed by Horst Parson, with its surrounding light band, remains fully preserved. The climbing walls float as a clear, new level above the mats, the altar remains visible and accessible. The necessary building services technology is almost invisibly outsourced, so that climbing is clearly recognizable as a new function without overshadowing the sacred space. The ventilation system necessary for high air exchange is housed in the raised attic of a southern extension. The exhaust air is returned around the building through the ground. The listed building remains largely free of conduit routing and installations.

Repurposing here does not mean replacing history, but rather continuing to write it – with respect for the place, architectural restraint, and new communal use.
