The Domaine de la Butte Ronde can host residential seminars, plenary sessions of up to 400 people, product launches, general meetings, gala dinners and weddings of 50 to 550 seated guests. The estate is fully privatizable and sleeps 153 people in 42 rooms. It covers 42 hectares on the edge of the Rambouillet forest at La Boissière-École, in the Yvelines, about 45 minutes from Paris.
Seminars and company events
The estate takes groups from 10 to 400 for working sessions: board meetings, plenaries, workshops, training, general meetings and product launches. The meeting rooms have a 5 by 2.5 m LED screen, professional sound, fiber internet and modular furniture. Day packages include an equipped meeting room, a private dining room, breaks and lunch; residential packages add accommodation, the pool and wellness area, and an evening at the Lodge. Meals range from food trucks and garden parties to themed and gourmet dinners, with a gala dinner served under the Grande Verrière. Team building uses the meadows, woods and pond: riding at the estate's stable, archery, escape games, cooking workshops, photo rallies and team games. A coordinator handles the event from the first request, and visits are possible seven days a week.
Weddings and receptions
Civil, religious and secular weddings are welcome, for 50 to 550 guests. The ceremony can take place on a private island in the pond, reached by a pontoon and shaded by trees, or in the Grande Verrière in bad weather. Drinks are served on the paved square with its fountain, in front of the Salle Séquoia or under cover. Dinner and dancing follow in the Grande Verrière or the Salle Séquoia, and the Lodge hosts the after-party. A brunch can be served the next day. The estate also hosts birthdays and bar and bat mitzvahs.
Rooms and capacities
The Salle Séquoia covers 585 m² and seats up to 550 guests, or 800 standing. It takes a plenary of up to 400 and divides into two rooms of 325 and 260 m², or three of 325, 156 and 104 m². The Grande Verrière, a glass hall with a solid parquet dance floor, seats 250 or takes 400 standing. The Lodge, 90 m², has a fireplace lounge, billiards and a bar for workshops or evening parties. Two wood-clad rooms of 50 m² each open onto the stable paddocks, with private terraces. A covered riding arena of 1,500 m² gives an all-weather backup for activities.
Accommodation
The estate has 153 beds in 42 rooms across seven buildings: Finnish, Alaska, Savoyard and Canadian chalets at the forest edge, guest rooms with exposed beams, studios and apartments above the stable, and the largest building, with eight rooms suited to groups.
Catering
Caterers come from the estate's list of partners, who know the site and cover traditional, kosher and halal cuisine and brunches. Both main halls have a caterer's office with a professional kitchen, and a catering coordinator is included for weddings. Seminar packages include meals arranged by the team.
History and setting
The estate, a former Mulliez family property, was taken over in February 2006 by Véronique and Xavier Levergne, who turned it into a leisure and reception venue while keeping its equestrian character. It combines meadows, woods, a pond with its island, century-old trees, a stable, an indoor pool, a sauna and a jacuzzi.
Getting there
The estate is at 78125 La Boissière-École. Paris is about 45 to 50 minutes by road, Rambouillet station 15 minutes by taxi, and Orly airport 55 minutes.
