The FCC – a green, climate-friendly urban sculpture
Our FCC project defines the transition from the dense, urban cityscape to the zoo’s landscaped park area. The organically curved building form serves as an iconic symbol of the Frankfurt Conservation Centre (FCC), whose mission is to bring the Earth’s biodiversity and natural heritage to life for present and future generations. The consistent timber-and-clay construction of the upper floors and the varied structure of the green, projecting shading system not only perform climate-regulating functions but also promote biodiversity on the building itself. The glazing, graded according to the cardinal directions, optimises daylight utilisation, solar gains and summer heat protection.
Generous, two-storey openings on the ground floor anchor the building within the urban landscape and create an inviting, permeable interface between interior and exterior spaces. Architecture, landscape and climate thus merge into a holistic, sustainable system that combines ecological responsibility, functional efficiency and an iconic presence.
The two-storey base level serves as an inviting introduction: it marks the shared entrance to the FCC and the zoo and creates a spatial threshold between the city and nature.
Views through and into the building, sculpturally designed clay stairwells and multi-storey conservatories create a carefully orchestrated sequence that guides visitors from the urban surroundings into the world of the FCC and the zoo.
The FCC’s visitor café opens out generously onto the terrace on the first floor and the rooftop café, offering a direct, attractive view of the zoo. It thus becomes a vibrant feature that brings life to the passageway and enhances the visitor experience. The interconnection of interior and exterior spaces, visual links and lounge areas enhances the overall experience of the building and also makes the café a place that defines the identity of the FCC.
The spaces become expressions of a holistic ecological approach – transitional areas that prepare visitors for the emotional transition into an environment committed to nature. Although the two parts of the building – the zoo and the FCC – remain functionally and organisationally independent, together with their respective residential units, they form a narrative tapestry of space, light, materiality and the experience of nature. In this way, the transition from urban space to the landscape can be experienced not only physically but also sensually. The building embodies an architecture that combines identity, sustainability and urban impact into an integral experience.
The compact building structure, combined with a layout grid tailored to the timber framework, forms the basis for an economical, resource-efficient construction method. The interior fit-out follows a modular principle: flexible partition walls allow for easy adaptation to changing usage requirements, enabling rooms to be reconfigured quickly, in a standardised manner and with minimal effort.
The building services have been deliberately kept to a minimum and focused on the essentials. Natural cross-ventilation and the thermal mass of the clay-timber beam ceilings render complex mechanical ventilation systems unnecessary in many areas. Surface heating and cooling are integral components of wall and floor elements; no additional technical or service ceilings are required.
The proportion of glass in the façades is functionally optimised: it allows sufficient daylight in whilst reducing heat gain. The proportion of openings is determined by the compass directions, whilst the gable ends are designated for façade-mounted PV. A high degree of prefabrication, particularly for timber and clay elements, enables rapid construction regardless of weather conditions
