The living room features a sofa from Engell; a suspended Parentesi lamp by Achille Castiglioni and Pio Manzù for Flos (Olsen’s “all-time favorite”); and a wood-burning stove made by Aduro. The firewood nook set in the left wall is Jensen’s own design. Olsen is responsible for the low planters around the perimeter, which she had fabricated from poured concrete framed in welded iron, with lacquered MDF panels for doors. “Some people laughed because we’d never had plants in our apartment,” she says. “So when we wanted a hedge, our friends were, like, Ok. Really? Good luck with that.” Photo by Anders Hviid.
