Île de Nantes, Bouffay, Les Machines de l'Île, Hangar à Bananes: we organise your activities in France's most creative city.
Bring your teams together for a half-day or a full day, with activities designed to unite, surprise, and create shared memories, from the streets of Bouffay to Les Machines de l'Île.
Our hosts travel to your premises, to a partner venue or to the heart of the Île de Nantes, and adapt each activity to your number of participants and your objective (onboarding, cohesion, celebration).
As a team building agency in Nantes, we build the idea with you rather than picking it from a catalogue. Treasure hunt from Bouffay to the Île de Nantes, blind test, corporate olympics at the Hangar à Bananes, creative workshops: each team building activity is chosen for what it achieves within the team.
As a team building organiser, we take care of everything: design, venue, logistics, on-the-day hosting, supplier coordination. The same project manager oversees your seminar and your corporate party. We cover the entire Nantes metropolitan area, from Rezé to the Île de Versailles.

Happy Unity is your team building agency in Nantes: we design, organise, and host your corporate seminars, corporate parties, treasure hunts, and themed days across Nantes Métropole and in Loire-Atlantique. From the medieval heart of Bouffay to the flourishing creativity of the Île de Nantes, our project managers oversee every detail, from venue selection to on-the-day coordination.
Whether your teams are based on the Île de Nantes, at the Hangar à Bananes, in the Bouffay district, or elsewhere in Pays de la Loire, we leverage a network of unique venues: the steampunk decor of Les Machines de l'Île, the Château des Ducs de Bretagne (Castle of the Dukes of Brittany), artists' lofts, and estates along the Loire or Côte de Jade. Organising a team building in Nantes, a seminar, or a corporate party becomes simple: a brief, a tailor-made proposal, and an event that leaves a lasting impression on your teams.
For each Nantes neighbourhood, we tell you what to see and the team building formats we best organise there.
Medieval heart of the city of dukes: restaurants, vaulted cellars, and event spaces at the foot of the castle.
