Lorraine style

Lorraine style in upmarket Belgian residential architecture designates the pastiche of grand French Lorraine manors and chateaux from the 17th and 18th centuries, imported into Wallonia at the turn of the 20th century. It is characterised by steeply pitched slate roofs, pedimented dormers, Meuse limestone facades, small-paned windows and ornamental moats or water features. It enjoyed a commercial revival in the 1980s and 1990s for chateau-hotels and converted manor residences. A notable point: Martin's Chateau du Lac in Genval, opened in 1981, remains the contemporary Belgian benchmark of the genre with its 121 lakeside rooms (Visit Belgium officiel, 2026).

Hospitality context
Martin's Chateau du Lac in Genval (Walloon Brabant) embodies this style with its clock tower, slate roofs and lakeside orientation. The hotel targets corporate retreats and weddings, offering 18 modular rooms and a gastronomic restaurant led by Pierre Resimont (two Michelin stars).
