This two-storey 1930s apartment on Gumshornsgatan, a trendy street in Stockholm’s Östermalm district has been transformed by designers Halleroed while retaining much of its original character. Embracing the modernist aesthetic, the designers skillfully reimagined the period while incorporating their own contemporary touches and flourishes. A badly considered floorplan was rationalised allowing the light-filled interior to shine. The star of the show though is the spiral staircase. I have visions of a 30’s beauty gliding down the stairs in a diaphanous evening gown of the time.
