Located roughly 2 km (1.24 miles) offshore from Poland in a bay in the Baltic Sea, the existing watch tower was used in the Second World War to guard a German experimental torpedo plant. It's now largely abandoned and in a sorry state, according to MFRMGR, though the firm says the site does receive some interest from film-makers and divers.
The architects plan to add a third story to the existing two story building, and also brick up some windows and add new windows where deemed appropriate. The top floor will include a bathroom, toilet, and sleeping quarters for up to eight people, while the first floor will feature a sauna, sundeck and storage. The ground floor will sport a kitchen, toilet, and common room.
According to MFRMGR, the facility will be operated using electricity generated from an as-yet undisclosed number of wind turbines and a solar power array, though a petrol generator will also be on site as a backup source of power. The firm also plans to add a rainwater collection system, a vegetable and herb garden, and a bird sanctuary.
