Seguin Sound is a terrace, restaurant and club on Île Seguin in Boulogne-Billancourt, set within the La Seine Musicale site. It can be hired for company evenings, afterworks, product launches, seminars and private parties, from 20 guests up to 800 for a full hire of the venue.
Seminars and company events
The official site lists a corporate afterwork, a client or staff evening, a product launch, a seminar or conference, a leaving party and themed evenings among the events it handles. The pitch is a single address with several moods: guests can start on the terrace with a drink, move to a cocktail dinner, and continue in the club without leaving the venue. Club access is included with the booking formulas described. A quote form promises an answer within two hours, every day of the week. There is no separate meeting room listed, so a seminar fits best as a presentation or conference in the restaurant and lounge area.
Weddings and receptions
Weddings are not mentioned on the pages we read. The venue speaks of birthdays, private evenings and themed parties, which suit a private reception with a DJ and a dance floor.
Rooms and capacities
Three event spaces are named. The Guinguette is the open-air terrace on the forecourt of La Seine Musicale, for afterworks, DJ sets and live concerts, from 20 to 400 people, and the site elsewhere says up to 500 for company or private use. The Restaurant and Lounge is modular and takes 20 to 150 guests for dinners and private events. The Club has a dance floor and DJ sets, for 100 to 500 people. A full hire of the venue is stated at up to 800 guests, and an organiser can also hire only part of the premises.
Catering
Two formulas are described. A cocktail dinner runs in three stages, with cold and hot pieces and a structured service, and a sharing-boards formula suits birthdays and groups. Drinks options include drink tickets, an open bar, bottles of wine and craft beers, since the venue also houses a micro-brewery. A private DJ, varied entertainment and a photobooth can be added.
History and setting
Île Seguin is the island in the Seine where the former Renault factory stood, now home to the concert hall La Seine Musicale. The venue sits at its forecourt, with the river around it.
Getting there
The address is 1 Parvis de l'Île Seguin, 92100 Boulogne-Billancourt, at the gates of Paris. The pages do not give public transport details, so nearest metro and parking should be checked with the team. Requests go through the quote form, by telephone or by email.
