“When I first showed my father round, he said it was too big and in too bad shape,” Andreas Martin-Löf chuckles, recalling an early site visit to his prospective new home in the former headquarters of AB Aerotransport, in the 1936 building overlooking the waters of Riddarfjärden. Specifically, they were looking at the apartment that belonged to Carl Florman, the airline’s charismatic founder, who Martin-Löf describes as finding curiously compelling for his: “Al Capone-like image - fond of hats and double-breasted suits”. The architect reminded his father that he is still young and has a lot of energy and, after 1.5 years of renovation, the apartment is now his home.
