Le Barn takes residential seminars, day meetings, team-building programs, product launches, press events, private parties and weddings. It offers five modular meeting rooms, 72 bedrooms and the option of hiring the whole estate on request. The hotel stands at the Moulin de Brétigny in Bonnelles, in the Yvelines, on the edge of the Rambouillet forest and in the Chevreuse valley, about 45 kilometers from Paris.
Seminars and company events
The hotel sells green seminars close to Paris. Work happens in the five modular rooms, which open onto the landscape and come with professional equipment. The shared spaces also serve as meeting areas: the restaurant, the bar, the kiosk and the terrace can host a breakout session, a working lunch or a cocktail.
The sales page lists several formats beyond the classic seminar. Product launches can use the indoor and outdoor spaces, for example a presentation under the trees or a cocktail by the pond. Press conferences and small conventions use the same rooms. Remote workers can book a day or a few hours and work from the restaurant, the bar or the terrace.
Team-building and incentive activities are offered on site, along with a wellness area with massages. Bicycles are lent to guests, and the estate gives direct access to the forest trails.
Weddings and receptions
The hotel hosts weddings, birthdays, family reunions and celebrations among friends. Reception spaces exist indoors and outdoors, and ceremonies can take place outside, in a meadow or a clearing. Banquets can be served outdoors or in an indoor room. The whole estate can be hired on request. Guests can stay overnight in the 72 bedrooms and use the wellness area and the activities the next day.
Rooms and capacities
The hotel does not publish the names or capacities of its five meeting rooms. Ask the events team for the seated and standing numbers of each room, and for the size of the restaurant and the kiosk, before you fix a layout.
Accommodation
The bedrooms sit in red barns that were restored and extended with cross-laminated timber. Categories include Classic, Superior, Superior Moulin, Superior Montana and Deluxe rooms, most opening onto a terrace or balcony, plus two suites: one in the former water mill, the other the largest suite on the estate. Three dormitories with eight single beds each suit younger teams or families. There is no fixed checkout time on Sundays.
The wellness area in the old mill has a sauna, a hammam, outdoor Nordic baths facing the paddocks, and massages.
Catering
The restaurant serves seasonal cooking built on vegetables from the estate garden and local producers. Meals can be taken under the glass roof, in the indoor rooms or on a large terrace facing the lawn and the forest. The bar serves cocktails made with herbs from the garden, and the kiosk faces the sunset.
History and setting
The hotel was created by William Kriegel, co-founder of the Haras de la Cense, a stud farm known for horsemanship based on animal behavior. The stud farm adjoins the hotel and offers rides from the estate. The estate covers 165 hectares of forest, meadows and a natural pond, where guests can row and swim in summer.
Getting there
By car, take the A10 from Paris and leave at exit 10 toward Dourdan and Saint-Arnoult-en-Yvelines. Three stations serve the area: Dourdan, 10 kilometers away on RER C from Austerlitz; Saint-Rémy-lès-Chevreuse, 15 kilometers away on RER B; and Rambouillet, 18 kilometers away on the Transilien N line from Montparnasse. Plan a shuttle for groups arriving by train.
