Zwarte Zwaan nature house, near Antwerp, Belgium

To the east of fashionable Antwerp are pockets of woodland where city folk escape for the weekend, including the Kempisch forest, home to Zwarte Zwaan, or “black swan”. This curvy black timber cabin with a living green roof was built in a neglected patch of forest in 2018, since when the replanting of 1,000 native trees has brought it back to life. A hot tub amid the greenery, a long forest swing, sauna and projector screen for film sessions boost the luxe factor, and within walking distance are a summer bar, nature trails, an ice-cream parlour and swimming pond.
