Château de Petit-Leez rents four spaces for seminars, company parties, weddings and family receptions, with seated dinners of up to 150 guests and theatre seating for 160. The estate is on Rue de Petit-Leez in Grand-Leez, in the Gembloux area of Walloon Brabant, and includes a 5-hectare park.
Seminars and company events
The château sells full-day seminar packages for 10 to 40 participants. A package covers the seminar room matched to the group size, a catering area, set-up, a screen, a projector and a flipchart. Participants get a welcome coffee with two mini pastries, a lunch and a drinks buffet that stays open all day.
Lunch comes in several styles: a standing lunch with sandwiches, with poke bowls, with salads, with an Indian street food truck, or with market-style stalls for at least 20 people. Soup of the day and dessert are part of the standard formats.
For larger meetings, La Grange seats 160 people in theatre layout. Inside, the small seminar room under La Grange, has a screen and projector and can serve as a break-out room: with the other spaces under La Grange, three separate groups can work at once. Add-ons include a closing drink, cabaret-style tables, a guided visit of the exhibitions, a nature walk, an engraving caravan and a percussion workshop.
Weddings and receptions
The château markets itself for weddings, receptions and family parties. La Grange suits a wedding dinner, and L'écurie, the former stables, works for an evening party or walking dinner. The Catalpa space opens onto the inner courtyard, the garden and a terrace, which gives guests somewhere to move between the ceremony, the drinks and the meal.
Rooms and capacities
La Grange is the largest room, on the upper floor under the roof frame, with daylight. It seats 150 for dinner and 160 in theatre layout. L'écurie seats up to 80 for dinner and opens onto the courtyard. Catalpa is three brick-vaulted rooms in a row, suited to receptions and meals for fewer than 50 people. Inside is the small seminar room with natural light and level access to the outside.
Catering
The château works with partner caterers: Gilles Cooremans, Grégoire, Grimod and Huîtrière et Eole. Three food trucks are also listed as partners: Tati Naan for Indian street food, Pasta Truck Épatez-moi for fresh pasta and Coffee Burger for burgers. Ask the team which caterer is compulsory for which format.
History and setting
The domain combines a walking park with several exhibition areas and a program of art, nature and events. Visits of the rooms are only possible by appointment.
