Hôtel Villa Pétrusse

Villa Pétrusse, nestled in Luxembourg City's Pétrusse Valley near the UNESCO-listed Old Town, is a restored 19th-century monument built in 1880 by architect Pierre Kemp, turned five-star boutique hotel. Once part of the city’s post-fortress transformation, it now features 22 rooms, a gourmet restaurant, public spaces, and gardens. The villa’s renovation honors its original materials through restoration and adaptive reuse, preserving its architectural soul. A hidden underground tunnel, part of the original casemates, was restored and opened to the public, now linking the villa to its pavilion.

The project presented a significant challenge: integrating the full range of five-star hotel amenities—including advanced ventilation, cooling systems, and en-suite bathrooms—into a listed former private residence characterized by wooden beam ceilings. Meeting the stringent fire protection standards required for public buildings added further complexity. The spatial layout was carefully restructured to separate guest circulation from service and back-of-house operations, ensuring both functionality and discretion. Additionally, areas affected by fungal damage had to be completely reconstructed, adhering to preservation standards while accommodating modern technical requirements. This delicate balance between heritage conservation and contemporary hospitality infrastructure demanded innovative architectural solutions and meticulous execution.

Villa Pétrusse’s transformation follows the principles of adaptive reuse, ensuring that all listed heritage materials were carefully preserved and restored for longterm longevity. Any new materials introduced were traditional locally sourced (as in the 19th century), installed using authentic craftsmanship techniques and know-how. As a heritage project it demanded complete preservation of existing structures, minimizing per se demolition and material waste. Water recovery systems were meticulously planned for sustainable water use in the park. All maintenance works are planned to be carried out by master artisans, using traditional methods such as gentle cleaning and regular inspections to protect the villa’s historical materials and details.
