Comet Meetings’ eighth Paris venue combines the charm of a listed building with the boldness of a new approach to corporate events.
Paris, 15 May 2025 — Behind a listed neo-Gothic façade, Le Grand Comet stands apart. A 19th-century former hospital with the look of a château, the building was first entirely restructured by its owner, the Hertford British Charitable Fund (HBCF), working with Maud Caubet Architectes and main contractor Fayat Bâtiment, before Comet, the European specialist in corporate events for 2 to 500 people, completed the transformation of its interiors. The result: a château unlike any other, where historic refinement meets the boldness of a set design inspired by the colourful, pop world of Wes Anderson, the American film-maker.

Contemporary and chic in equal measure, Le Grand Comet sets a new benchmark for large-scale corporate events: off-sites, training sessions, cocktail receptions, summer parties, team building and conferences. A venue designed and run to bring people together, inspire them and make professional exchange easier, without the financial, logistical and environmental constraints of events held far from the city.
From hospital to events venue: a château reinvented for business
Built in 1877 by the architect Paul-Ernest Sanson and originally funded by Sir Richard Wallace, the British philanthropist behind the famous Paris drinking fountains, the château is a valuable witness to the architectural heritage of the Paris region. Comet is launching a new facet of its business here, blending that heritage with cinematic references to the world of The Grand Budapest Hotel. Built around the idea of a hotel, the interior design borrows its visual codes: a key rack, a lift attendant, a reception desk. The whole is embodied by a cast of characters, known as « residents », whose personalities inspire and shape the interiors of each floor. Madame Paulson, Messrs Wallace and Brown and Mademoiselle Agatha each give their space a unique, immersive identity.

The new venue, named Le Grand Comet as a nod to the Wes Anderson film, spans 1,800 sq m over three floors, with 11 modular rooms filled with natural light and a 1,000 sq m private garden. All just minutes from Paris on metro line 3. An elegant, memorable and unique playing field for off-sites, training sessions, workshops, cocktail receptions and team building.

Comet’s event offering: fully customisable and turnkey
Designed to host up to 110 people seated or 300 standing, Le Grand Comet is ERP-certified, like every Comet Meetings venue. The venue is conceived and run to answer the needs of companies that want to make an impression on their stakeholders, bring them together, entertain or inform them, without the logistical complexity that usually comes with events. At Comet Levallois, also known as Le Grand Comet, the offer includes:
- Three floors, each fully privatisable
- Customisable interior spaces of every size
- A large landscaped green outdoor space
- A turnkey formula: room hire or whole-floor privatisation, bespoke layout, catering and snacks, equipment and tech support, advice and logistics
- High-end catering, endlessly customisable and in step with today’s expectations: seasonal, local, healthy and varied
- A dedicated Meeting Scientist for every client and every project, to orchestrate each event from start to finish
- Wellness sessions drawing on sophrology, yoga and meditation, offered to guests so they arrive at their meeting relaxed and clear-headed
- Digital booking through Cosmos, Comet’s in-house platform, which generates quotes almost instantly
Every event is conceived as a high point: memorable, unifying, smoothly and seamlessly delivered, in a setting as inspiring as it is functional.

Bespoke services to go further
Beyond the venue and the logistical support, Comet also takes care of content, making available a whole ecosystem of expertise to enrich every event:
- Facilitators and moderators, to drive discussion and spark collective intelligence
- Inspiring speakers on leadership, innovation and change
- Content creators (photo, video, illustration), to capture the moment
- Event entertainment on request (DJ sets, workshops, performances and more)

Strong momentum already
Since bookings opened in early 2025, close to 100 events have already been confirmed. Several CAC 40 companies have chosen Le Grand Comet for their next milestones: training sessions, summer parties and off-sites.
Conceived as a living, privatisable and adaptable venue, Le Grand Comet will also run original one-off event formats throughout the year: garden meetings, pop-up talks, seated dinners and outdoor team building.

A project serving the public interest
Le Grand Comet is at once a heritage, social and innovation project. The Hertford British Charitable Fund, which owns the building, is a century-old association dedicated to supporting people with a connection to Great Britain whose wellbeing is at risk or who face serious hardship.
The rental income generated by the HBCF will allow it to continue funding associations and other charitable works, keeping Sir Wallace’s legacy alive in France.
