Listed German real estate firm Colonia has said that one of its subsidiaries has sold its trophy office property 'Disch-Haus' in Cologne for over EUR 40 mln. The transaction with the unidentified buyer was achieved by the sale of the special purpose vehicle which owned the asset. The SVP was a joint venture between major shareholders UBS and Redos Real Estate, and Colonia. The deal is expected to close in January 2009.
