As one of Södertälje's more recent church buildings, Brunnsängs kyrka reflects a late twentieth-century approach to parish architecture, designed to sit comfortably within the surrounding residential district rather than dominate it. It stands close to the local district centre, with an adjoining park and an open green area that is sometimes used for parish activities.
Inside, the church's most distinctive feature is its three-part altarpiece, made up of fifteen watercolour paintings by the artist Sven H Johansson. The building also houses a parish hall, reflecting its role as a community as well as a devotional space.
In recent years the church has apparently become an increasingly popular choice for confirmations, though this is noted as a general trend rather than a documented statistic.
