Josef Moroder Lusenberg and his son Josef had Sonnenburg erected in 1904 on the site of the old mill at Cudanbach stream. A workshop for sacred sculpture was set up on the ground floor, where Josef Jr. built up an ecclesiastical art business. The turn-of-the-century building stands out thanks to its half-hipped roof, which is rare for Gröden, bay window and turret with a sundial painted on the wall beneath some double arched windows.

The old Lusenberg farmhouse (in Ladin Jumbierch) was converted into a bourgeois dwelling in 1830 by Annamaria Pezlauzer Moroder. She was the grandmother of the sculptor and painter Josef Moroder (1846-1939), who added the name of the house to his own. Moroder Lusenberg set up his painter's atelier, which is still in its original state, on the upper floor. His second wife Felizita ran an antiques business from there. The sculpture workshop on the ground floor is also in its original state. Moroder's grandson, Harald Schmalzl, still works there today as a sculptor.
