Kalbornia Lake & Pool House is a single-storey, wood-clad holiday home on the shore of Lake Dąbrowa Wielka, in the Masurian Lake District of northern Poland, with a colourful mosaic floor covering its interior. The architecture is by Boris Kudlička with Partners, who collaborated with Aleksandra Sowa of ASID Studio for the interiors, which were based on a wildflower meadow.
