3 days · 2 nights · 6 to 15 people
Residential seminar in a private estate, one hour from Paris
Three days to work, to pull the team together and to sleep well on site.
The seminar that does not stop at six
Work, dine and sleep in the same place
In a residential seminar the most useful time is often the time nobody scheduled: the morning coffee, the walk through the grounds, the conversation that carries on after dinner. At the Chesnay-Haguest everything happens on one estate, and that estate hosts nobody but you.
The bedrooms are bright, with embroidered linen and modern bathrooms, and the Monet and Dumas lounges take the late evenings. The three lounges let you alternate between plenary and workshops. For a bigger moment, the Pavillon du Parc becomes a plenary room facing a stage. Between sessions, the pool, the tennis court and the 5 hectares of grounds are open to everyone.
Which teams is it for?
- A team or department seminar of 6 to 15 people, all sleeping at the estate
- A start-of-year seminar, a cohesion seminar or a project kick-off
- Onboarding a newly formed team
How far from Paris?
One hour and ten minutes from La Défense and from central Paris by the A14 and the A13, 40 minutes from Mantes-la-Jolie and 45 from Cergy-Pontoise. By train, allow 45 minutes from Saint-Lazare to Vernon-Giverny, then 15 minutes of shuttle. Far enough that nobody goes home to sleep, close enough that you do not sacrifice half a day to the journey. See the countryside estate one hour from Paris.

Night at the estate
When the meetings stop, the estate takes over.
The session ends at six. The stay does not. None of this is on the programme, and it is often what teams remember best.
The lounges
In the evening the day's conversations carry on in the Monet and Dumas lounges, differently.
The stars
The château's telescope comes out onto the lawn. Far from city lights, the Vexin sky does the rest.
The silence
No neighbours, no traffic, no other group. Night here does not sound the way it does in town.
Dawn
A coffee in hand, mist over the grounds and the 250-year-old cedar, before the first session.

They have been here
“We were looking for somewhere that would take the team out of its routine without turning the trip into an expedition. Four days at the estate, with everyone sleeping on site: the evenings did as much as the working sessions.”
Frequently asked questions
How many people can sleep on site?
15 people, each in their own bed, across the 10 bedrooms of the estate. For a larger group we can arrange partner accommodation nearby.
How is this different from a strategy retreat?
The residential seminar is for a team: cohesion, a project kick-off, the start of a year. The strategy retreat brings a leadership team together around deeper decisions. Same estate, different pace and different schedule.
What does 590 € excl. VAT per person cover?
Exclusive use of the estate for three days, the equipped lounges, the grounds, two nights on site (120 € excl. VAT per night) and five meals (50 € excl. VAT per meal). Activities and the shuttle are added according to your programme.
Can we extend to four days?
Yes, each extra night and meal is added to the quote. The Opti Digital seminar ran over four days and three nights.
Can you organise activities?
Yes, built around your objectives, from coaching through to lighter formats: outdoor games, tennis, archery tag. Tell us what you want the stay to produce and we build the programme with you.
