Designed by the architect Sture Frölén, the church was built as Trångsund grew into a proper town in the 1950s. It served as the sole parish church until 1987, when Mariakyrkan in nearby Skogås was inaugurated and took over that role. In 1974 Tacksägelsekyrkan had become the parish church of the newly formed Trångsund parish, previously part of Huddinge parish.
The building is modest in scale, with seating for around a hundred, reflecting its origins as a local community church rather than a grand civic landmark. It has light-coloured rendered walls and a steep, slate-clad saddle roof. One entire long wall of the nave is glazed, filling the small worship space with light from the surrounding woodland. Sources differ slightly on which side of the building this glazing occupies, but agree that it is a defining feature of the interior.
Within these windows, striking stained glass by the artist Ebba Wadsten (sometimes spelled Vadsten) depicts the Road to Emmaus, dating from around 1960. The altar crucifix is also notable: made of silver with a blue enamel image of Christ, it was designed by the silversmith Birger Haglund.
The church bells hang in a separate timber-built bell tower rather than in the main building. The organ has an interesting history of its own: the original instrument, built in 1958 by Grönlunds Orgelbyggeri, was moved to Segeltorp church in 1961 and replaced by a new mechanical organ from the same builder, which remains in use.
Today the church hosts a number of services throughout the year and is where most christenings, weddings and funerals in the parish take place, with a room for funeral refreshments on the ground floor.
