Villa Bönnhoff, Heritage villa in Alt-Wetter, Germany.

Villa Bönnhoff is a residential house in Alt-Wetter built on a steep hillside with a high sandstone base, a northern tower, and a prominent entrance staircase. The structure uses local Ruhr sandstone throughout and features a distinctive layout oriented toward the valley below.

The house was built between 1901 and 1902 as a commission for foundry owner Carl Bönnhoff, designed by architect Rudolf Plies from Wuppertal-Elberfeld. Since 2009, it has housed Café Bonheur, giving the villa a new purpose as a cultural venue.

The name and design reflect the prosperity that the original owner gained through his foundry business. Inside, you can see craftsmanship displayed through hallways and staircases decorated with multi-colored stucco marble details.

The villa stands on a slope above Kaiserstraße, so the entrance is reached by a broad staircase from street level. The café that opened after the 2007 restoration has been closed since the operator announced a personal break in 2018, and it is not known whether it will reopen. Check locally before planning a visit.

The villa sits on a slope above the Ruhr valley, a short distance from the former Bönnhoff factory, so the family could keep an eye on the works. From 1976 to 2007 the town of Wetter ran a youth centre in the building, long before the café era.
