A junction box extension method and apparatus for creating additional space proximate an existing junction box without having to remove the existing junction box. The junction box extension has an open box with a lip on one side and a rim on the other, a flange for holding the box proximate the existing junction box where the lip of the open box protrudes beyond the wall, and a cover to provide a finished appearance as the junction box extension engages the junction box to provide additional useable space.
