The headquarters of Helm AG are situated on Nordkanalstraße 28 in Hamburg.
Together with the adjacent “Hanse-Haus” office block on Nordkanalstraße 29, the building forms an urban architectural ensemble. The buildings were constructed in 1964 respectively1972 and are almost identical regarding the basic structure of their plan layout.
The design principle of the existing façade as a window-band is largely maintained and accentuated with a new design motif. The contrast between the glass windows and the parapet strip is emphasised, whilst a newly added fold in the cladding adds an additional accentuation.
In the context of the reconstruction of the headquarters, a connecting bridge spanning across Nordkanalstraße will be constructed between both buildings on the second floor above the terrace level.
