Arsenalsgatan 8, Bank building in Norrmalm, Stockholm, Sweden

Arsenalsgatan 8 is a five-story Jugend building from 1907–1909, designed by Thor Thorén with a fire gable by Ferdinand Boberg. Its ground floor and ornamentation are in red sandstone, contrasting with light smooth-plastered upper floors, and it is crowned by a black slate roof. Two glass-covered bank halls stand in the courtyard.

Built in 1907–1909 for Bankirfirman E. Öhman j:r and Kommanditbolaget lantmanna- och kreditkassan D. Aronowitsch & Co., the house was designed by Thor Thorén, then working for Öhman's new architectural office alongside Ferdinand Boberg, who drew its fire gable. Two glass-covered bank halls were added in the courtyard; the southern one housed Aronowitsch until Östergötlands enskilda bank took over in 1920, and the northern one held Öhman's office before AB Affärsbanken used it around 1920.

The building demonstrates how Stockholm's financial district evolved, with two glass-roofed banking halls that once served different Swedish banking institutions over many decades. These halls still shape how people move through and experience the space today.

The building sits near Blasieholmstorg square in central Stockholm and is easy to reach on foot. Visitors can access the hotel, restaurants, and rooftop bar to explore the space and take in views across the city.

The two glass-roofed banking halls stand in the courtyard, not on the street: the southern one housed D. Aronowitsch & Co. until Östergötlands enskilda bank took over in 1920, the northern one served Bankirfirman Öhman and around 1920 AB Affärsbanken. Ferdinand Boberg, Thorén's colleague at Öhman's drawing office, designed the building's fire gable.
