New-York-Ring 6 und 6a, Cultural heritage monument in Winterhude, Hamburg.

New-York-Ring 6 und 6a, the Edeka-Gebäude, is an office complex in Hamburg's City Nord business district, completed in 1974 as Edeka's headquarters. Two L-shaped wings meet at a central core of lifts, stairs and escalators, and the facade keeps its original light exposed-concrete escape balconies, modelled on facades by Kenzo Tange.

In 1970 Edeka decided to concentrate its central administration, spread over more than 20 Hamburg locations, in a new building in City Nord. Construction began on 24 April 1972, the foundation stone was laid on 26 September 1972 and the topping-out ceremony was held on 2 November 1973; the building was completed in 1974. The competition brief, based on staff surveys, required no full air conditioning and offices for at most eight workstations.

The building's name comes from its main user: Edeka has occupied it since 1974, and the group's headquarters are still here. The original interior gave each floor its own colour for all signage, set against dark ceilings. Employees once had a food shop, a branch of the company's own Edekabank, a sports hall, a fitness room and a sauna on site.

The office complex is not open to the public, so visits are limited to viewing the facade from the surrounding streets of the City Nord office district. The U1 subway stop Sengelmannstraße and several bus lines serve the area, and the nearby Stadtpark offers walking paths and a planetarium for a longer stay.

The facade's wrap-around escape balconies in light exposed concrete were modelled on facades by Japanese architect Kenzo Tange, turning a purely functional element into the building's sculptural structure. The facade still shows its original state and original colour scheme.
