The first church in Våmhus was a wooden chapel built in 1635, consisting of a rectangular nave with a straight-ended chancel and an attached sacristy. It was enlarged around 1651 and given a new porch, and in 1659 its wooden vaulted ceiling was decorated with paintings depicting the life of Christ, from the Annunciation to the Last Judgement, along with a depiction of Paradise. A further sacristy was added in 1727 before the chapel was demolished in 1789.
The present stone church, built in a late Gustavian style, stands about a hundred metres north-west of the old chapel site. Its foundations were laid in the early 1770s, but construction stalled and only resumed in 1780; the building was brought into use in 1789 and formally completed and consecrated in 1794. It has a rectangular nave with a straight chancel to the east, a three-sided sacristy as wide as the nave, and a square west tower topped with an octagonal lantern and an onion-shaped spire. The main entrance lies at the base of the tower, with a further door on the south side of the nave, and the roof is a mansard form, hipped above the sacristy.
Inside, the barrel-vaulted wooden ceiling was decorated during a restoration in the 1950s, and the floor combines brick in the aisles with wooden boards beneath the pews.
Several furnishings were carried over from the old chapel, including an octagonal wooden font dating from 1662 and an earlier seventeenth-century pulpit. The current pulpit, made in 1806 by Krång Lars Ersson of Sollerön to designs by Gustaf Ulrik Boman of Stockholm, has a three-sided, rounded body with a matching sounding-board above; beneath it hangs a gilded dove carved in 1810. The altarpiece dates from 1807. Two church bells also survive from the old chapel: the smaller bell was originally used at Mora church, bought in 1651 and recast in 1672, while the larger bell was cast in Stockholm in 1735.
The present organ, in the west gallery, was built in 1973 by the Gothenburg firm Hammarbergs Orgelbyggeri and has mechanical key action with an electric stop action.
