Both the exterior and interior of the Malmi church are of red brick. The exterior wall of the church is decorated with brick ornamentation with a cross theme, like in medieval stone churches. The church, completed in 1981, was designed by architect Kristian Gullichsen.

The church is wide, to keep the parish close to the altar. For the rest of the architecture, Gullichsen has borrowed consciously from Alvar Aalto. There fireplace wall is an imitation of Villa Mairea. The roof of the music hall looks like it is from the Vyborg library. The story goes that, owing to the resemblance, Gullichsen planned to mark the roof with quotation marks made of tiles.

The church is 13 metres high. Light flows from the skylights along the unevenly laid altar wall. The lighting fixtures on the church walls imitate the torch lighting of a monastery. The floor of the hall is made of Nunnanlahti soapstone, the ceiling of pine panels and the benches of pine. The altar and the font base are made of Lapland marble, the pulpit and altar stand of soapstone. The pulpit, altar and font were designed jointly by Academician, Bertel Gardberg, and Kristian Gullichsen. The church silver and the bronze church rooster on the ridge of the church roof are by Bertel Gardberg.

The eight-metre high, shield-shaped work by Maija Lavonen on the church wall, claimed to be the largest church textile in Finland, the centre of which is changed depending on the colour of the ecclesiastical year, also refers to the medieval tradition. The liturgical textiles of the church were designed by textile artist, Piila Saksela. The work, Taivaaseenastuminen (Ascension) on the choir window was made by artist, Juhana Blomstedt. The crucifix cast in bronze on the altar wall is the handiwork of sculptor, Arvo Siikamäki.

The church organ was built by the Hans Heinrich organ builder at Maksamaa. It was completed in 1984.

In compliance with the ancient method of church construction, the entrance to the inner court of the church is through the bell tower. The tower has three bronze bells. The steel bell of the temporary Malmi church has been placed in the through-passage of the tower.

The facilities of the church building are grouped onto three levels. The church, parish meeting hall and music room are located on the middle floor.

The office building in the courtyard area of the church is connected to the church by a pergola. The church is surrounded by an 85-metre-long stone wall, which together with the office building and pergola forms a closed inner courtyard in front of the main entrance of the church. There is an outdoor terrace on the side of the park.

The Malmi church is the main church of the Malmi parish.

Members of the church can organise a baptism, a wedding or a funeral free of charge in the church.
