In the living room, there is an iron fireplace by Danish manufacturer Aduro. A futon can be converted into a double bed for additional guests. Two sliding glass doors open onto the terrace. “It is a really peaceful and quite interesting atmosphere,” Laugsch says. “We have a fireplace in the boat to curl up on the couch with a glass wine after a day of sightseeing.”

A wooden patio wraps around three-fourths of the house boat. The living room cushions can be removed and used on the deck. A ladder dips into the water for swimming in the summer.

“My brother and I were searching for a place of our own that we could rent to people visiting Berlin,” says co-owner Chris Laugsch. “We found the boat by accident in a Berlin marina. After a few minutes on the boat, we knew we found the place.”

The kitchen countertop and floor are both Pandomo, a poured concrete surface. The ceiling is a stained pine. Floor-to-ceiling glass windows cover two of the largest walls on the boat.

The one-man sauna is created by three architects at modulorbeat, Marc Günnewig, Jan Kampshoff, and Sebastian Gatz. They were inspired by the nature of the former factory site, which reflects the changing state of manufacturing in the region. “When we arrived, looking for a location, [we thought] it was so beautiful how the nature came back to the industrial site,” says Kampshoff. “We transformed it into a space with an urban quality.”

The slim, 25-foot-high tower adds up to a mere 140 square feet, spread out over three levels.

Visitors are meant to progress from level to level at their leisure. “The ritual of the sauna is going into the sauna box, jumping into the cold water, and then relaxing,” says Kampshoff. “All concrete elements are simply stacked on another and there is a gap of light between each one, offering breathing space.”

Visitors climb from level to level via a retractable steel ladder, which begins at the ground-floor plunge pool. The architects used industrial materials like steel and concrete throughout to "keep it raw,” according to Kampshoff.

On the second floor lies a timber wood sauna with two-level seating. “The sauna box itself was custom and pre-fabricated,” says Kampshoff.

One can climb up another ladder, built into the concrete walls, to get a view of the surrounding landscape. “The stairs are the typical kind of stairs you use in shaft buildings,” says Kampshoff. “It fits well with the rough appearance of the building.”

The view from the top of the tower. “Work is leaving our region and we have a huge area that we don’t know how to develop,” says Kampshoff. “If you look into the history of work in this region, we always had big companies. It’s all disappeared. We came up with the idea of how we deal with these work sites. The sauna is the opposite of work—it’s relaxing."
