The Palace of Versailles, Trianons, royal gardens, and châteaux of the Yvelines: we design, organise, and host your team events on the doorstep of Paris, in a setting befitting your key moments.
Reconnect your teams for a half-day or a full day, with activities designed to unite, surprise, and create shared memories, from the park's vistas to the reception rooms of the city centre's private mansions.
Our hosts travel to your premises, to a partner estate, or right in the heart of Versailles, adapting each activity to your number of participants and your objective: integration, cohesion, celebration.
As a team building agency in Versailles, we build the idea with you rather than pulling it from a catalogue. A treasure hunt around the Palace and its park, corporate olympics in the gardens, a rally to the Trianons, creative workshops: each team building activity is chosen for what it achieves within the team.
A dedicated project manager oversees the organisation from start to finish, right up to hosting your corporate party. We cover Versailles and the entire Yvelines department, from Saint-Germain-en-Laye to Rambouillet and their forests.

More than 850 events a year. What we have learnt: the client should feel no logistical effort at all. Our process is built for exactly that.
You tell us about your teams, your goal, your date and your budget. We genuinely listen: no 40-field form.
2 to 3 reasoned scenarios: venue, activity, logistics, itemised budget. You choose, we fine-tune, we launch.
Our crew is on site. You arrive as a participant, not as the organiser. As an option, the aftermovie is delivered at D+7.
Tell us your group size, your date and what you want your team to get out of the day: your Event Expert sends you a costed proposal within 24 hours. Free, with no commitment. Prices in euros, excl. VAT.
Indicative pricing · the final price depends on the venue, the season and the options you choose
