The former insurance bank building on Frederiksplein in Amsterdam was constructed in 1967 and designed by Arthur Staal (1907-1993). As a modernist, Arthur Staal was challenged to form a relationship in the façades between two historical adjacent buildings. This resulted in a modern and independent office building along the square that references the historical situation and location, on the corner of the Utrechtsestraat. After years of neglect and ad hoc renovations, the former bank building is in need of restoration and sustainable modernization. With respect for Staal's design, Office Winhov’s transformation strengthens and reveals the building’s original character. The plasticity, the rhythm and the special roof endings, which are characteristic of the facades of Staal, are all reintroduced in the new façade which meets today’s sustainable requirements. The structure of the building and the central main staircase are the only remnants of the original interior. The travertine that Staal used in the public areas and around the stairs has been reused. The office atmosphere of the 1960s served as a source of inspiration for the new interior design. A vertical structure of shafts was chosen because of the limited height in the building, which makes the interior more spacious. This creates a simple layout with a transparent central core and an open network of meeting rooms around it. The top floor of the building, where Staal opted for an expressive roof finish, will house an office restaurant. Current owner Egeria will be partially using the building.
