The Lauttasaari church, completed in 1958, was designed by architects, Keijo and Marja Petäjä. The church represents the lean but easy-to-approach architecture of its time.

Monumental stairs lined with walls of boulders lead to the church. An erratic boulder standing in a paved water pool decorates the inner court. The almost 61 metre high bell tower dominates the cityscape of Lauttasaari.

The aisle to the choir is paved with mottled marble from Lapland. The interior, lighting and communion set were designed by interior architect, Ilmari Tapiovaara. Representing constructive, original design, the communion cup and the handle of the flagon are decorated with precious stones. Instead of an altarpiece, there is a wooden cross by architect, Petäjä. The church textiles are by Annikki and Ilmari Tapiovaara and artist, Hilkka Vuorinen.

The organ was built by the Kangasala organ factory. It has 39 stops. The choir organ was produced by organ builder, Veikko Virtanen in 2000. The three bronze bells were cast by Veljekset Friis Oy.

The Lauttasaari church is used by the Lauttasaari parish. The St. Jacobs church for the Swedish parish, Johannes församlingen, is in the same building.
