Spanning two floors – connected by a jaw-dropping helical staircase – the home of Acne Studios chairman Mikael Schiller is extraordinary yet unfussy and totally comfortable with itself. With the input of interior designer Daniel Östman, the Stockholm apartment features a range of artwork, bold colour choices and clever design inspiration from Donald Judd and Richard Serra. It also shows the creative side of the business brain behind the cult fashion brand, now a global phenomenon. Photographed for WSJ Magazine, the grandeur Schiller’s home is immediately apparent, but so is the cosiness and boundless energy.
