La PY Sphère is a modular event room of 100 m² at 10 rue Gustave Rouanet in the 18th arrondissement of Paris, at the foot of the Montmartre hill. It is rented bare, with 50 chairs for the full space, for seminars, team building, afterworks, workshops and private celebrations.
Seminars and company events
The creative director Pierre-Yves Le Strat founded the room in 2015. The official site calls it a confidential, warm place with many resources, used by companies that want to meet, find inspiration and create synergies. It adds that the format suits very small companies, start-ups and regional groups.
Two rental formats are offered on weekdays. The first is a 50 m² space with tables and 25 chairs, rented by the half day. The second is the full 100 m² with tables and 50 chairs, rented by the day. Both include a video projector, paperboard and whiteboard, sound, Wi-Fi 6 and a technician at your disposal. Options for the half-day format are a coffee break, lunch and a video-conferencing kit. Options for the full-day format are a cocktail, an animation and a photo report.
Rooms and capacities
The room is a single, adaptable space of 100 m² whose decoration is handmade. It can be used whole or as a 50 m² half. The seating given on the site is 25 chairs for the smaller format and 50 chairs for the full space. A standing capacity is not published, so ask if you plan a cocktail with more guests.
The agency behind the room, Even Event, also lists other Île-de-France spaces that suit different sizes: Le Loft 75 (365 m², Paris 10th), La Cave d'Issy (150 m², or 75 m² as a half-room), Sweet 18 (500 m²), Les Salles Claires (400 m²) and Square (600 m², up to 200 people, Paris 16th). It mentions more than 60 partner venues in total.
Catering
Even Event runs a catering service and says it has chosen chefs for their skill, simplicity and flexibility. Menus are built from short-circuit, seasonal products with attention to food waste. The agency also builds photo booths, a pétanque court and other activities, and provides audiovisual services with a stage and cinema technician.
History and setting
The room describes itself as an event third place at the foot of the Montmartre hill, with ingenious modular furniture and home-made decoration. Individuals use it to celebrate milestones, and artists and cultural groups to develop projects.
