The Crystal Houses feature glass bricks that dissolve into terracotta

MVRDV’s Crystal Houses began its existence with the request of Warenar to design a flagship store combining both Dutch heritage and international architecture on the PC Hooftstraat, Amsterdam’s one and only luxury brand street that was previously primarily residential. MVRDV wanted to make a representation of the original buildings and found a solution through an extensive use of glass. The near full-glass façade mimics the original design, down to the layering of the bricks and the details of the window frames, but is stretched vertically to comply with updated zoning laws and to allow for an increase in interior space. Glass bricks stretch up the façade of Crystal Houses, eventually dissolving into a traditional terracotta brick façade for the apartments (as stipulated in the City’s aesthetics rules), which appears to be floating above the shop floor.

Solid glass bricks were individually cast and crafted by Poesia in Resana, near Venice. Research undertaken by the Delft University of Technology, in partnership with engineering firm ABT and contractor Wessels Zeist, led to the development of structural solutions and fabrication techniques, with the use of a high-strength, UV bonded, transparent adhesive from Delo Industrial Adhesives in Germany to cement the bricks together without the need for a more traditional mortar. Despite its delicate looks, strength tests by the Delft University of Technology team proved that the glass-construction was in many ways stronger than concrete. The full-glass architrave, for instance, could withstand a force of up to 42.000 Newton; the equivalent to two full-sized SUVs.
