The chapel has a basilica form and active cross-section. Light streams in from both the side naves and from the clearstory windows, positioned on the walls of the central nave. The side naves are separated from the main nave with arches, where the spandrels are richly decorated. The architect was engrossed with stave church architecture, which is easily evident in the Neiden Chapel. Here the central nave appears similar to the raised central rooms seen in stave churches. While the side naves, stairwell and sacristy behave like stave church porticos.
