There are properties that are difficult to define by conventional standards. This extraordinary penthouse apartment is one of them.

The building underwent comprehensive renovation in 2011, was equipped with new triple-glazed windows in 2023, and was further upgraded in 2026 with high-quality appliances, custom oak carpentry work, and a new climate system.

Cathedral-like ceiling heights, white-stained exposed beams, and generous glazing characterize the architecture. Daylight enters from three sides as well as through motorized Gerber-Vogt roof windows and reaches the living area via an open gallery and a glass element in the floor. A wood-burning stove forms its centerpiece, while the distinctive pentagonal dormer frames views into the surrounding treetops.

The apartment features two bedrooms and an open gallery. The master bedroom offers generous built-in wardrobes. The second bedroom, currently used as a music room, was restored in 2026 with a floor-to-ceiling oak partition wall and custom sound-insulated sliding doors by Tschudin AG, and can seamlessly open into the living area or be completely separated from it. The open gallery provides additional sleeping and working areas beneath motorized roof windows and a glass balustrade with a view into the living room below. A discreet climate system provides pleasant cooling throughout the apartment – a particularly valuable feature of a historic Basel penthouse.

The defining outdoor highlight is the private roof terrace of approximately 29 m² with panoramic views over the treetops and rooftops of Basel extending into the surrounding landscape. It is complemented by a kitchen balcony of approximately 6 m², whose complete renovation is scheduled for autumn 2026, has already been approved, and is fully financed by the condominium association.

Functionality also impresses: The travertine bathroom with Villeroy & Boch sanitary fixtures features a rain shower and bathtub, while the kitchen boasts a seamless black quartz cooking island and high-quality Siemens appliances. Oak wood floors with underfloor heating, integrated storage space, washing machine and dryer in the apartment, and a restored goods lift with a load capacity of up to 250 kg round out the high living comfort.

The offering is completed by a private garage box with exclusive usage rights to the access road. It is separately registered in the land register and can be acquired together with the apartment for CHF 55,000.
