Solar Egg is an enormous elegant eggshaped woodburning sauna by Bigert & Bergstrom. The project is part of an urban redevelopment effort in Kiruna, the northernmost city in Sweden. The egg has a height of five meters and can seat up to eight people. It is comprised of a pine wood interior and has highly reflective goldplated steel exterior panels that reflect the environment surrounding the sauna. In the center rests a heartshaped stove cast from iron. Solar Egg is a sculptural symbol meant to prompt thoughts of rebirth. The sauna occupies a key position in the arctic climate of Lapland and is intended as a room for warmth and reflection. It is an incubator that nurtures conversation and the exchange of ideas. When not in use, Solar Egg can be broken down into 69 separate components parts, rendering the entire sauna completely mobile.
