It’s the name of Radagast’s house. Yes! he is the eccentric wizard from the Hobbit: The Desolation of Smaug.

This build by Jonas (Legopard) is awesome and big, but what caught my interest was the small details in this build (you should looks closely). The blue bird, the sledge, the rocking chair, and many more.
