Upon its completion in 1992, Rijnstraat 8, the former Ministry of Housing, Spatial Planning and the Environment (VROM) building represented both an innovative office typology – its atriums served as conservatories where the outside was brought inside – and a leading example of sustainability. Today the building, designed in the 1980s, no longer offers the flexibility and openness required of a contemporary office space. In collaboration with the original architect, Jan Hoogstad, and in the context of a Public Private Partnership under the name of PoortCentraal (consisting of BAM, ISS and OMA), OMA has developed an integrated concept for the building based on a renewal of its existing architectural qualities.
