Saunas

The sauna is raised above the ground using four wooden stilts in order to minimise its impact on the surrounding environment.

Australian art and architecture collective Studio Rain has installed a temporary sauna next to a Melbourne's Yarra River, which is prefabricated and off-grid so that it can be built, disassembled and reused without the use of heavy machinery.

Unlike many back-garden outbuildings created in the UK that contain office space, the Dark Spa is dedicated to leisure. It contains a sauna, Japanese soaking tub, shower, gym and relaxation room with a fold-down bed.

As its name suggests, the Dark Spa was designed to contrast to the extension's pale brick exterior, and is clad in charred black timber.

More than 95 per cent of the timber used for this sauna in Finland was sourced, processed and constructed locally, helping to minimise the carbon footprint.

The Arctic Sauna Pavilion, located by a lake in Lapland, Finland, has a distinctive geometric shape with walls that have been tilted outwards. This is a traditional way of making storage buildings in Lapland to stop the timber wall construction from getting wet.

Finnish studio Toni Yli-Suvanto Architects has created a black timber pavilion that functions both as a sauna and a hub for social activities.

Inside, Sommarhus H is divided into two zones. The left zone hosts the private spaces, including bedrooms and a south-facing sauna that looks out onto the beach.

A sauna in Seattle floats on a lake on a pontoon that users can swim off in between sessions. Built after the local community raised funds with Kickstarter donations, WA Sauna can be reached by kayak or boat.

Built on a sledge base, Denizen Sauna can be towed off its island in Finland and onto a frozen lake. Once out on the ice, a hole can be cut through the crust to make the perfect plunge pool to round off the full Scandinavian sauna experience.

Students from an architecture school in Oslo built The Bands as part of their graduate show. The seaside sauna steps down over the rocky coast, creating terraces for users to sit, soak in a sunken hot tub, or picnic on the built-in barbecues.

Perched on a craggy outcrop on the shore of Lake Huron, Grotto is a private sauna with a cavernous interior of curving cedar-clad benches, nooks and porthole windows.

German architecture collective Modulorbeat repurposed concrete components normally used to build underground mines to create a vertical sauna shaft in Germany.

Decades of iron ore mining in Kiruna destabilised the land under the town and now the whole settlement is being relocated. To help residents worried about the loss of community spirit in the move, artist duo Bigert & Bergström created this sculptural sauna.

Local residents worked with Berlin-based studio Raumlabor to build the Gothenburg Public Sauna. A wooden bridge projects out in to a harbour to link the sauna on stilts, which is clad in sheets of rusty corrugated metal.

Small Architecture Workshop avoided disturbing any nature on the banks around a lake in Åmot, Sweden, by building a sauna for tourists on a floating platform.
