The property is located in a popular Riehen location, not far from the town center with its numerous shopping opportunities. The surrounding residential area is quiet and characterized by an excellent neighborhood. The easily accessible green areas and recreational areas further enhance the quality of the property.

The residential building, built by the nationally known architects Ernst Mumenthaler + Otto Meier on behalf of the client Professor Alder, impresses with its striking compact, yet voluminous building shape and the distinctive concrete facade - which may seem strict at first glance, but unfolds a special calmness, durability, and presence upon closer inspection. The design of the surroundings with the long and cypress-lined access to the house-internal garage is no less impressive.

The floor plans are extremely generous over three levels and offer a diverse room program, so that the most different space requirements (family, guests, living + working) can be fulfilled.

The property was comprehensively modernized just a few years ago and therefore presents itself in an excellent structural condition and with a high-quality interior design. Thanks to the numerous window and terrace openings, all levels benefit from optimal natural light, which underlines the unique living quality and the exclusive ambiance.

Raw exposed concrete, a sculptural building body, and powerful horizontal lines make the "Haus Alder", listed in the inventory of protected buildings, a rare private example of brutalist architecture - authentic in its origin, yet carefully modernized for today's living.
