Text description provided by the architects. New connection between two listed monuments.
Van Stigt Thans occupies a refined and stylish listed building on Lange Nieuwstraat in Schiedam. In 2003 Mei architects and planners constructed a glazed addition on the ground floor to connect with an adjoining monumental warehouse bought by Van Stigt Thans.
Now that the top floor of both buildings will be used for residential purposes, Van Stigt Thans has asked Mei to construct a second connecting bridge. This is a complex challenge owing to the difficulty of bridging the height difference, the demands that come with working on a listed structure, and the need for privacy. The design proposal was immediately enthusiastically received by the municipal design review committee for new building permits and monuments, precisely because Mei articulated its addition as a new time layer. Mei succeeded in strengthening the value of both buildings by respecting and preserving their existing character.
The solution found by Mei did not involve repeating the glazed connection. Instead, it proposes a white ‘cloud’. The new bridge, a self-supporting structure of steel and glass, is faced in white perforated steel panels. Refined, abstract 3D motifs that refer to the original cast-iron ornaments of the balconies of the listed building are incorporated into the panels by means of rubber presses. To ensure the privacy of occupants, what happens inside cannot be seen from outside, but occupants do enjoy views out of the building.
The design is measured by means of a point cloud and then the 3D-BIM model is elaborated on this scanned base layer. The bridge is reversible to allow future owners to remove it if desired. The warehouse can also be restored to its original condition because the openings made in the facade for the bridge have the same proportions as the original window frames.
