seaside castle for sale Bordeaux, France

South Gironde — 18th-century château, 45 minutes from Bordeaux, set on an exceptional, history-steeped airial (traditional Landes clearing) within the unique environment of the Landes de Gascogne Regional Natural Park. A former barony with origins dating back to the 13th century, built in ashlar stone in an elegant architectural triptych inspired by French classicism. 3,200 m² of built area on a little over 7 hectares, crossed by a lagoon and framed by majestic cedars. Comprising five buildings whose essential structural works were rehabilitated in 2023 by BPM ARCHITECTE (Bordeaux): traditional oak timber frames, new roofs, restored façades and consolidated masonry. An approved permit, cleared of appeals, now authorizes the creation of an upscale senior residence of 40+ units with services and retail. Other uses remain possible: private estate, multi-generational residence, wellness, cultural or retreat venue. Not subject to heritage listing constraints, the property offers real freedom of use: its scale, location and character make it an ideal base for a high-value collective project. Perfectly suited to a vision led by a group of investors or an operator seeking a singular site ready to be reborn. 3D renderings by BPM ARCHITECTE. Comprehensive file and viewing on request.
