The Sonlez Mill is an exceptional heritage property located in the heart of the Sûre Valley, in the municipality of Winseler in northwestern Luxembourg. This historic residence dating from the 17th century offers a living area of 591 m² intelligently spread over five distinct levels and a total built area of 970 m², consisting of forty-three rooms, eleven bedrooms, and four bathrooms. The entire property is set on over twenty hectares of meadows, woods, and hedges, creating a bucolic and secure environment. Architecture and volumes The building features four facades and a high-quality exterior envelope. The main facade is approximately thirty-two meters wide, oriented northwest. The ground floor (312 m²) comprises the reception area with entrance hall, two spacious living rooms (37.78 m² and 35.33 m² with fireplace), equipped kitchen, game room, bedroom, two garages (offering four parking spaces), blue stone cloakroom, versatile annexes, and two separate toilets. The first floor (383 m²) focuses on the living space: open-plan living room with kitchen of 50 m², equipped kitchen, night hall serving six bedrooms, two bathrooms, and an office. This level also includes an exceptional barn of 157 m² with a ceiling height of 7.85 m. The second floor (117 m²) hosts four additional bedrooms, two bathrooms, a partially convertible attic, and a separate toilet. The third floor includes an unfinished attic of 79 m² with development potential. The basement houses two vaulted cellars (each approximately 27-37 m²) and the boiler room. Technical facilities: Oil-fired central heating, 2,750-liter tank, integrated fiber optic. Overall condition of the building: to be refreshed. Environment and grounds The property benefits from an exceptional setting on 20 hectares 13 ares 91 centiares (≈ 201,391 m²) composed of natural meadows, woods, and hedges. The rear garden, enclosed and landscaped with lawn, faces southeast with naturally sloping terrain and unobstructed views. The lateral left garden combines woods and lawn, facing northeast, with protective slope. Private gravel driveway. Front parking: six spaces. Two covered garages: four additional spaces. Location and context Sonlez is among the oldest villages in Luxembourg, documented since the Frankish period of the 8th century. The village remains Walloon-speaking — one of the few to have remained in the Grand Duchy after the London Treaty of 1839 — giving it a distinctive cultural identity. Accessibility: A25 motorway 2.1 km | Bastogne (Belgium) 12 km | Rail access 14 km | School 2.2 km | Shops and restaurants Pommerloch 2.1-2.3 km | Bus 9.4 km. Despite this road proximity, the Mill's isolation remains remarkable: minimal car traffic, calm and preserved environment, setting conducive to prestigious rural living or heritage project. Reconversion potentials Extended family house: subdivision of spaces accommodates large or multi-generational families. Seminar or creative retreat: volumes, capacity (11 bedrooms, 4 bathrooms), and isolation make it a distinct candidate. Agricultural or environmental project: Twenty hectares allow ecological management, amateur orchard, or landscaped development. Summary The Sonlez Mill is much more than a residential property: it is a living real estate heritage, a focal point of local memory for three centuries, having played a significant role in the history of regional public services. Priced at €2,950,000, it offers a rare opportunity for buyers seeking rural authenticity, exceptional capacity, or heritage potential for reconversion. For international buyers: direct access to Walloon traditions, history of the Battle of the Ardennes, and a protected ecological environment in northwest Europe. --- Luxembourg prestige property · Historic 17th-century mill · Sûre Valley · 20 hectares of land · 11 bedrooms barn reconversion · Walloon heritage · Ardennes Battle · Luxury tourist gîte · Heritage investment · Winseler Sonlez · Prestigious house border Belgium
