The Rotterdam architect Henk Hupkes built a great many churches for the Dutch Reformed denomination whose forms became increasingly expressive, though material-wise he never strayed from brick. His later designs such as De Christengemeenschap on Lumeystraat in Blijdorp and this Immanuelkerk are sculptural and organic with traces of anthroposophical architecture. Here a spiralling brick wall begins at the tower above the entrance and ends at the sanctuary; the main church space is on the first floor. The unfinished brick walls of the whole are enlivened with decorative brickwork and concrete gargoyles. Glazing in the edges of the roof delivers daylight into the church's white-rendered interior.
