La Tréso can be hired for private events of 14 to 100 guests: seminars, conferences, company parties, birthdays and team workshops. The venue is a cooperative third place at 8 avenue du Président Wilson in Malakoff, in the Hauts-de-Seine, directly south of Paris. It opened in September 2020 and combines a modular café-canteen, a professional kitchen, shared craft studios and a fablab.
Seminars and company events
The official site presents the space for seminars and conferences as well as for private parties. Hire takes place outside the normal opening hours, so your group has the room to itself. The team offers sound and projection, use of the kitchen and the bar, a caterer, and entertainment. One contact person on the venue side follows your event from the first request to the day itself.
A distinctive option for teams is the workshop format. The craft makers on site run group sessions in woodworking, embroidery or T-shirt printing, and the fablab offers sessions on digital machines such as the laser cutter and the CNC milling machine. A custom cooking class can also be organized with the kitchen team. These sessions suit team cohesion days, where the group makes something together before or after a working session.
Rooms and capacities
The ground floor holds up to 80 guests standing, 65 seated without tables and 50 seated at tables. The first floor adds room for 20 more people. The space is modular, so the layout can follow the event: a plenary setup for a talk, a standing reception, or banquet tables.
Hire slots depend on the day. Sunday and Monday run from 10 a.m. to 11 p.m. Tuesday and Wednesday are available from 6 p.m. to 11 p.m., and the end of the booking can be extended to 1 a.m. for a supplement. Other days are possible with an exceptional closure of the venue, subject to availability.
Catering
The kitchen team can propose a formula depending on the format and the date. It cannot currently offer a full catering service on Sundays, so groups can bring their own caterer or supply part of the meal. Use of the refrigerators is decided case by case. There is no corkage fee: you can bring your drinks, or order from the bar's menu on quotation, and part of the bar refrigerators can be cleared to chill your bottles.
You may bring decoration or flowers. Everything must be removed and cleaned at the end, since the venue has no storage area. The space must be returned in the state it was found, and cleaning supplies and bags are provided. A cleaning service can be added.
History and setting
La Tréso is run as a cooperative and describes itself as a place of lives and fabrications. Alongside private hire, it runs a public program of workshops, a repair café, concerts and themed evenings. The related Le Toboggan project, a temporary urban planning initiative with the city of Malakoff, has hosted about 20 artisans, artists and associations since January 2025. A reduced rate exists for Malakoff residents and for social and solidarity economy organizations.
Getting there
The venue is close to metro line 13, the Paris ring road and the T3A tram. Step-free access is possible through the Passage du Nord, at the back of the building, by crossing the parking area. The official site says the team usually answers within 48 working hours with availability, and a deposit secures the date.
