Architects Bertil Harström and Johan Krauppi have created a free-floating hotel on one of Sweden’s longest rivers, with the micro-destination featuring a spa among its offerings.

Owned and conceptualised by the architectural duo, the circular Arctic Bath Hotel and Spa will float on the Lule River during the summer months, with the structure frozen in place through the winter.

The main circular building has a design inspired by a log jam and features six rooms, another 12 are elevated on poles onshore. There’s also a spa, restaurant and lounge.

The bijou spa has just one treatment room offering treatments by Kerstin Florian and its sister brand ANDA, which is both organic and vegan.

Additional facilities include an outdoor cold bath – a circular pool at the building’s centre – as well as saunas, a steam sauna and thermal baths.

The outdoor cold bath will be available all year, as during the winter the pool will be kept free from ice. During summer, the midnight sun will allow guests to swim outside both day and night.

Guests will also be offered a range of activities such as moose calling, bear watching, northern lights photography, dog sledging, nature walks, snowshoe hiking, cross-country skiing and yoga.
