Jouin Manku has designed the extension for Hotel Les Haras. A spa, several meeting rooms and 60 new rooms were created inside a 19th-century building, which is just across the street from the old site of the Royal Stud Farm. The main challenge the two designers faced was to maintain a sense of unity going from one building to another. Their solution was to rehabilitate an old, abandoned tunnel linking the two buildings, and develop a concept of continuity and connectivity. Ultimately, the new project took on a character of its own, paying tribute to the soul of the existing premises and remaining faithful to the spirit of Hotel Les Haras.
