Yes Mag shows you how easy it is to make a bee house with this tutorial and accompanying video.
From the site:

Mason bees are a common bee you will see flying around your home in spring and summer. They are native, non-social bees. They neither sting nor make honey.
The mason bee is an important pollinator. This blue-black metallic bee nests in hollow stems, woodpecker holes, and insect holes found in trees or wood.
