The interior design by Kraaijvanger Architects responds to PostNL's needs as a new user of the Stationspostgebouw and their desire for a new environment that serves flexible collaboration, flexible use and the well-being of employees and guests. These ingredients have been translated into a social landscape; an environment for working, research and development, focused on collaboration, exchange and connection. The transformation of the special building has been leading in the 'mapping' of activities linked to different areas in the interior; dynamic and informal zones around the voids for meetings, informal and formal zones for collaboration and consultation, surrounded by open, semi-open and closed spaces. And also a more quiet periphery where one can work individually and in peace in the narrow part of the building.
In order to create the most pleasant working environment possible, mainly natural and technical materials have been used in the interior, such as resp. wood, clay plaster, brick from residual flows, textile and magnetic gray colored glass, aluminum, self-healing steel and terrazzo made with a bio-based binder. The materials determine the interior design. They speak for themselves and are applied undisguised and undecorated. The result is a powerful collaboration of constructive expression and a unique mix in which the restored architecture and the new interior reinforce each other, where the value of the building's history is translated into the interior; no use of ornaments but a fair and simple application of materials.
