Herpain Urbis has sold the Solaris in Brussels to Fidentia Real Estate Investments’ specialised investments vehicle Fidentia Green Buildings. CB Richard Ellis (CBRE) advised the vendors. The Solaris represents a new trend in sustainable building. Designed by architectural firm Assar, the building is scheduled for completion in the first quarter of 2009 and will be one of the first buildings conforming to environmental certification standards expected to be adapted in the EU in 2009.
