[1][2] The Kyrkjebø Church's architecture is based on the classical lines and derives from Gothic cathedral designs.

This design was as much the result of architectural choice as of the technical requirements for building churches that emerged during the 19th century.

The improvement in technology and crafting techniques at the turn of the century had led to churches adopting a lighter form and employing elaborate detailing.

[3] In 1670, the church was enlarged to the north side by adding a transept to create a partial cruciform design.

In 1986–1987, a small extension on the north side was torn down and replaced with a larger one that houses a bathroom and other storage rooms.
