Seminars and company events
The estate welcomes seminars, team-building days, retirement parties, year-end events, conferences, product launches and strategy conventions. Three meeting rooms inside the château each take up to 50 people. A heatable marquee of 200 m² in front of the château holds up to 200, and two modular marquees of 36 m² can be set up. Rooms come with a projector, screen, paperboard and whiteboard. Team-building options include a climate workshop, dance classes, a cooking workshop led by a chef, in-house Olympic games, guided electric bike rides in the nearby Hez forest, a murder party for up to 50 people indoors, and yoga.
Weddings and receptions
The estate can be privatized for weddings of 40 to 200 guests. The château, its five guest rooms, two terraces of 300 m² each, the 200 m² marquee in the garden and the chalets and bungalows are all included in a privatization. The couple can get ready on site, hold the cocktail hour and take photos in the grounds, and a brunch is available the next day. A historic church stands 300 meters away for church ceremonies. For birthdays, three salons of the château, the terraces and the marquee receive guests.
Rooms and capacities
The two terraces suit a cocktail hour in several layouts. Indoors, the three château salons and meeting rooms serve for smaller groups. The marquee is the main space for large dinners and parties, with room for up to 200.

The domain lists 22 chalets and bungalows, 47 bedrooms and 86 beds in total. Twelve chalets have a private spa or jacuzzi, ten are classic chalets or bungalows, five guest rooms are in the château, and one spa chalet is adapted for reduced mobility. The estate states it can lodge up to 130 people.
Catering
Meals use local products, and the estate serves breakfast with local produce. A chef leads cooking workshops for teams. The site does not describe a set caterer, so confirm catering terms when you ask for a quote.
History and setting
The domain is family run, and the owners combine French and Brazilian heritage. The park surrounds a pond and lies next to the Hez forest. The château is heated by geothermal energy, and the estate sorts and composts its waste.
