An elevated public platform within Herzog and de Meuron’s Hamburg Elbphilharmonie has been officially opened, along with building’s restaurants, cafés, bars and hotel.

Following nine and a half years of construction, the City of Hamburg has taken delivery of the building from construction firm Hochtief, and a ceremony to mark the milestone was held on 5 November.

Former dock workers and local students were among 200 Hamburg residents invited to experience the public viewing platform for the first time.

Situated between the former warehouse building, which now houses the venue’s car park, and the new glass structure located above it, which hosts two concert halls, the 37m high observation deck offers views of the city and its harbour and features an exterior walkway around the building.

Visitors reach the deck, which is conceived as a public plaza, via an 82m long curved escalator which leads to a large panorama window. From there, the path follows a second smaller escalator and spaciously designed stairs to the deck itself.

“The Elbphilharmonie is much more than just a spectacular concert hall,” said Herzog and de Meuron in a statement. “It’s a unique place, which reflects Hamburg’s social and cultural life.

“With the plaza, we wanted to create a place for everyone with a unique panorama: the outward-looking design of the spacious terrace, sprawling on the warehouse like a new public square, counterbalances the inward focus of the philharmonic hall above it.”

The plaza also houses the stairs to the concert halls, the lobby of The Westin Hamburg hotel and a café.
