Hochbunker Barmbeker Straße, Wartime bunker in Winterhude, Hamburg, Germany

The Hochbunker Barmbeker Straße is a rectangular concrete air-raid shelter whose facade is split into red, grey and tan stained-concrete sections, with two columns of recessed multi-paned windows and a single central column. A wide band of blue glass runs beneath the flat, curved white roof overhang, and the entrance sits at the base centre.

Constructed in 1943 during World War II, this bunker provided protection for hundreds of Hamburg residents during aerial bombardments and was later converted into temporary housing during the postwar reconstruction period.

The building is a Hochbunker, a tall above-ground shelter type built in Hamburg from 1940 onward, not a Flak tower. Its nickname among locals refers to the bunker's wartime role; today the converted structure is known by the address Barmbeker Straße 183-185 and the name ONE83 LOFTS.

Following extensive renovations between 2015 and 2016, the structure now houses the ONE83 LOFTS residential complex, featuring modern apartments with a penthouse addition while maintaining the original exterior at Barmbeker Straße 183-185.

The 2015–2016 conversion added a penthouse on the roof, so the wartime silhouette changed for the first time in decades. The facade keeps its three-part division in red, grey and tan stained concrete, with a band of blue glass beneath the curved white roofline.
