Inside, the church has a low barrel vault, whereas the choir, following renovation in the 1970s, is set off by three lower vaults that open towards the aisle. There was previously a curtain, which was used to conceal the altar section when the church room was being used for something other than ecclesiastical activity.

Plans for an assembly house in Vestre Jakobselv date back to 1929-1930, when the departed midwife Annette Lilleeng bestowed her first major donation towards an assembly house in memory of her parents. Her father, the teacher Thomas Lilleeng, had been the Laestadian preacher. At that time, there was talk of a parish council house with a large and small hall and a kitchen. The combination of a school within a school chapel was discussed, but rejected in order to be able to allocate the use of the house freely to all the main specifications set out in the letter of donation.
