Domaine de Béhoust hosts residential seminars, training programs and leadership meetings for groups of up to 170 people in a plenary layout, with 104 bedrooms on site so that a whole team can work, eat and sleep in one place. The estate is a Régence-style château in the village of Béhoust, in the Yvelines department west of Paris, and it is run by Chateauform, a group that specializes in seminar houses.
Seminars and company events
The house is built for business groups. Nineteen meeting rooms are arranged around a central atrium, which keeps breakout sessions close to the plenary room and makes moving between sessions quick. Seventeen of these rooms are modular and take from 20 to 170 participants. The venue states maximum layouts of 170 in theater style, 120 in islands, 28 around a conference table and 26 in a U-shape. The format suits a two-day management seminar, a sales kickoff, a training cycle that returns several times a year, or a board meeting that needs a quiet room and a dinner afterwards.
Team activities are part of the offer. Outdoors, groups can use tennis courts, a multisport court, football and volleyball areas, a pétanque ground, a golf practice area and mountain bikes in a 14-hectare park. Indoors there is a pool, a sauna, a hammam, a fitness room, billiards, table football, pinball and karaoke. The activity catalog also lists organized team games such as an escape game and Olympics-style challenges.
Rooms and capacities
The largest room covers 356 square meters and seats the full plenary of 170 in theater style. Jefferson is an auditorium with 55 seats over 71 square meters, useful for presentations and talks. A fixed-table room seats 10 over 35 square meters for a board or steering committee. The other rooms can be reconfigured between sessions, from workshops of 20 to larger subgroups.
Accommodation
All 104 bedrooms are on the estate. Participants stay where they work, which removes transfers in the morning and in the evening and lets a program run late without extra logistics.
Catering
Meals are prepared in house by the estate's chef, with a seasonal menu. The Café Mondain, a former stable under a glass roof, serves as a bar and informal lounge, with musical instruments for the evenings. Catering is included in the day packages that Chateauform sells per participant, so an organizer does not need to book an outside caterer.
History and setting
The château is built in the Régence style and stands in a quiet village of the Yvelines, surrounded by its own 14-hectare park. Former outbuildings, including the stable now used as the Café Mondain, have been converted for groups, while the main house keeps its period character. The setting gives a team a change of scene without a long journey.
Getting there
Béhoust is about 40 minutes by road from Paris, according to the venue. The village lies in the countryside west of the capital, so a team based in the Paris region can arrive on the morning of the first day. Ask the house about the nearest train station and shuttle options when planning a group arrival.
