The heritage-protected headquarters of the Senate Department for Urban Development, Construction, and Housing has undergone extensive refurbishment. The focus was on a resource-efficient construction approach to ensure the long-term continued use of the ageing building. For the restoration of the iconic facade of Berlin's former tallest office high-rise, 3,500 bespoke 3D elements made of glassfibre reinforced concrete were used. Custom-designed L- and V-shaped components in the colour ivory were delivered as ready-to-install elements. These suspended facade elements are materially authentic and reflect a timeless aesthetic in keeping with the building's heritage status. This careful approach preserved the historically significant exterior while seamlessly blending conservation with contemporary architecture. The durable concrete elements enabled a visually appealing modernisation of the building envelope, maximising its lifespan. Photos: Ditz Fejer
