Maison Sage is a design loft of 250 m² spread over two levels at 15 boulevard Saint-Martin, in the 3rd arrondissement of Paris. Companies hire it for corporate evenings, product launches, afterworks, client events, study days, showcases and shoots, for up to 200 people. The team states that it does not take events for private individuals.
Seminars and company events
The loft works as a seminar room by day. The official site lists workshops, brainstorming sessions, team meetings and full study days, with movable furniture, a video projector, a sound system, high-speed wifi and areas set aside for meals and breaks. Formulas run for a half day or a full day, with or without catering, and outside speakers or activities can be added to the program. A team member follows the project from the first brief to the event itself.
In the evening the same space changes mode. Maison Sage supplies a professional sound and lighting system, an equipped bar, a backstage area and furniture. Corporate evenings, end-of-shoot parties, afterworks, showcases, after-shows and vernissages are all on the list of formats. Film and photo shoots can also use the loft, which makes it practical for a brand that wants to shoot content in the morning and host guests at night.
Rooms and capacities
The official site does not name individual rooms. It describes one loft of 250 m² on two levels, combining artistic decor, intimate corners, vintage furniture and private bars. The stated maximum is 200 guests for the whole venue. The layout is modular, so a smaller group can use it in a more compact setup and keep the atmosphere of a lounge rather than a hall. Seated capacity for a plenary session or a dinner is not published, so ask for a floor plan that matches your headcount before you commit.
Catering
Catering is an option, not a fixed package. A caterer, a DJ and entertainment can be added to an evening, and the equipped bar handles drinks service. For seminars, the formulas exist with or without a meal, which lets you leave lunch out of the booking if your group eats elsewhere. Dietary requirements and menus are settled with the team when you request a quote.
Getting there
Maison Sage stands on boulevard Saint-Martin, in central Paris, on the edge of the 3rd and 10th arrondissements. The official site says the loft is easy to reach by public transport. The Strasbourg - Saint-Denis metro station is a short walk away, and the Gare de l'Est and Gare du Nord train stations are both close, which helps when part of your group travels in by train. Guests arriving by car should plan on public parking in the surrounding streets, as the site does not mention private parking.
