In one of the most sought-after locations in Lörrach-Stetten, directly on the border with Riehen (BS), stands this architect's villa - solidly built, clearly structured and in excellent, continuously maintained condition. Basel can be reached in around 20 minutes by car, tram or S-Bahn. The house offers approximately 269 m² of living space on two levels, as well as a basement with approximately 211 m² of usable space - a total of around 480 m² of usable space and approximately 2,000 m³ of enclosed space. Continuous slate floors, floor-to-ceiling Schüco windows and underfloor heating characterize the living floors. The heart of the house is the 61 m² large living/dining area with a fireplace, which opens onto the glass-covered terrace and garden through large sliding doors; next to it is the Strato kitchen with a cooking island. Four more rooms on the ground floor, on the upper floor the parent's suite with dressing room and bathroom, as well as two roof terraces of 69 m² each - the west terrace with a panorama over Lörrach and the Tüllinger Berg to Basel and the Vosges. The house is fully basement - and the basement is much more than storage space: with 2.50 m room height and large windows, there is a 60 m² large hobby and fitness room with parquet, a guest room and a wellness area with sauna and separate garden access, all with underfloor heating. Next to the classic cellar rooms: laundry room, technology, storage. An underground, code-secured passage connects the house to the triple garage; the spacious forecourt offers parking spaces for additional vehicles. The approximately 1,457 m² large, fully fenced plot is inaccessible from the viewing side. The pool (10 × 4 m) with electric cover, lavender, fruit trees and Mediterranean planting create the feeling of a private holiday home in the summer - sunsets over Basel included. Irrigation and lawn care run automatically. The house technology is up to date: heating system (2024), photovoltaics with storage and wall box (2025), BUS system for lighting, blinds and heating, alarm system and Siedle video intercom.
