The church was built in 1849 by master builder Erik Jonsson, who also constructed Vilhelmina kyrka and is thought to have reused the same designs, attributed to architect Axel Almfelt. It has a timber-log frame with a rectangular nave, a straight-ended chancel to the east, an attached sacristy, and a tower to the west. The exterior is clad in plain vertical panelling, with saddle roofs on the nave and a pulpit roof on the sacristy, both covered in pointed wooden shingles.
Inside, the walls are panelled and painted grey-white, while the ceiling takes the form of a barrel vault decorated with a blue-and-white coffered pattern, giving the interior a light, orderly character typical of many Norrland parish churches of this period.
Among the furnishings is a wooden font with gilded carving made in 1946 by Birger Lindahl of Lövånger, paired with a silver bowl donated to the church in 1967. A red chasuble surviving from the late fifteenth century is a notable link to the pre-Reformation past, long before the present building existed. The round, pale grey-painted pulpit may follow designs associated with architect Per Wilhelm Palmroth, who designed Lycksele kyrka in 1799.
The church has had a succession of organs. An instrument built in 1758 by Jonas Wistenius of Linköping was moved here from Lekeryd church in 1888, followed by a new organ from Nils Oskar Alm of Boden in 1909, which was itself later relocated to Nyåker church in 1943. The current pneumatic organ, built in 1947 by Grönlunds Orgelfabrik of Notviken, retains the older organ case as its facade.
The church and its former rectory, now used as a parish hall, continue to serve as a focal point for community life in the Örträsk area.
