In the spring of 2017, architects from five Estonian and five Belgian architectural firms took a deep dive into a number of urban design and architecture problems facing the city of Brussels. The issues were selected based on expertise from the firms. How could the security of critically important buildings in the city be improved? How could urban planning and architecture contribute to a more coherent society? How might a more digital society change the physical city around us?The site-specific conclusions and solutions suggested by the architects will form the core of the exhibition titled BEL:EST - A Laboratory for Europe in Brussels, which will open during the Tallinn Architecture Biennale TAB 2017 in Estonia in September 2017. Subsequently the exhibition will travel to Brussels, to BOZAR, to present the case studies to the Brussels public. The exhibition is curated by Aet Ader (a promising young Estonian architect from the b210 office, and Vice-Chairman of the Estonian Association of Architects), and is produced by BOZAR and the Estonian Centre of Architecture.The offices from Estonia include: Salto, b210, Arhitekt Must, PART and KAOS Arhitektid.The offices from Belgium include: L’escaut, AgwA, Delmulle & Delmulle, Bogdan & Van Broeck and Lassa.
