In Frankfurt, three existing buildings, including a historic, listed villa from around 1900, as well as two extensions from 1980 and 2003, were carefully renovated and modernized with an emphasis on energy sustainability. A key goal of the facade renovation and interior design was to establish a cohesive aesthetic between the three interconnected buildings. The architectural references were intended to create a harmonious overall look within the ensemble, integrating smoothly with the park-like setting. INDUSTRIA, an investment manager specializing in residential properties, relocated to two of the revitalized buildings. At Building 15, the old metal facade was replaced with a plaster finish in a light shade. The building’s base and vertical pilasters were clad in three-dimensional glassfibre reinforced concrete elements, adding structured accents to the exterior. Photos: Ditz Fejer
