Refurbishment Zeissig, Völksen-Springe

The office building of the Zeissig company dates back to the 1960s. In the 1990s, an extension and an additional floor were added and inaugurated in 1991. The entrance façade and the glazed extensions on the western and northern sides of the office building have aged considerably and exhibit a low energy performance as well as an outdated architectural appearance.
Over the years, the existing solid-construction building has undergone several alterations, resulting in an inconsistent architectural expression both internally and externally. As a consequence, the building currently appears fragmented and visually incoherent.
The aim of the project is to renew the public appearance of the Zeissig company, create additional floor space and at the same time establish a clearer spatial structure within the existing building. In addition, an energy-efficient modernisation of the building is planned.
As part of the project, the single-floor glazed extension on the north and west sides of the existing building will be removed due to energy and functional requirements. In its place, a two-floor timber extension is planned in order to provide additional office space and achieve a more efficient use of the site. The existing building and the new extension will receive a shared ventilated rainscreen façade.
A key design focus lies in strengthening the building's address towards the west. In order to create a representative entrance area, the extension of the office building will receive a recessed entrance zone. In front of this entrance area stands the existing "Eichenhammer" sculpture, which will be integrated into the entrance ensemble.
