The Grosshaus belonged to one of the most prosperous and influential residents of Diemtigen, Jakob Reber. This is why the residence of this public official and local dignitary is very presentable.

Built in 1805 by Jakob Reber. Master carpenter unknown. Jakob Reber held numerous offices in the municipality and was one of the most prosperous and influential residents of Diemtigen. He also owned the Trogmatte (Dorf 32), whose housebarn (Styggässli 20) he commissioned the master carpenter Hans Messerli to build in 1779. In 1792 he commissioned the same craftsman to build the Ründihaus (arched-gable house) in Wiler.

The imposing residence of this public official and local dignitary impresses thanks to its location, generous proportions and façade with twin flights of stone stairs leading up to the artistically carved front door ornamented with metalwork. Abundant flat carvings.
