Architects von Gerkan, Marg and Partners (gmp Architekten) have won the first prize in the competition for the extension of Gebr. Heinemann Headquarters in Hamburg’s HafenCity. The new building designed for the Hamburg-based, tradition-rich trading company impressed the jury as “an independent urban-planning and architectural contribution characterized by timeless, harmoniously self-contained architecture.” Viewed from the northwest, the new extension is a companion piece to the Maritime Museum, with the two buildings flanking the “Heinemann-Speicher” in the middle. From the Ericus Bridge, the new construction highlights the corner of the ensemble on Shanghaiallee and makes a characteristically urban statement. More images and architects’ description after the break.
