The church was designed by architect Roland Hedenström of Täby, working with Bo Grefberg of Stockholm, who had previously designed the nearby Sälen and Gammelsätern mountain chapels. Its twelve-metre-high interior is noted for a striking sense of space and uplift, and the building is oriented to the four points of the compass, seating around 150 people. The first Christmas morning service was held here in 1984, while the church was still only half finished.
The altar, standing in the eastern corner, was made and donated by Pell Olle Eriksson. Above it hangs a carved ring-cross painted in rainbow colours, encircled by a gilded sun bearing Christian symbols, the work of artist Bengt Lidström of Umeå. The wooden altar candlesticks, with their spiral-turned stems, were a gift from the Tandådalen Fjällhotell in 1985, and a wrought-iron candle-bearer shaped like two mountain birches, designed by Thomas Hellström and forged by Matts Fällman, is used daily and during services.
A freestanding open bell tower stands just east of the chapel, topped with a pyramid-shaped roof; its 300kg bell was cast at the Bergholtz bell foundry in Sigtuna.
In 1992 the church was extended into what is often described as a church community house, following a decision by the Diocese of Västerås to invest in mountain church activities. The extension added a gathering hall with a tall open fireplace built of Älvdalen stone reaching to the ceiling, a large kitchen, and an adjoining building known locally as the kyrkstuga, almost as spacious as the church itself. Staff offices occupy the basement level. Ownership and running of the church passed through a dedicated mountain church association and fundraising foundation before being transferred, along with Sälen's fjällkyrka, to the Diocese of Västerås in 2012.
