Conferences, seminars, workshops, gala dinners, product launches, trade shows, weddings and concerts for 5 to 900 guests can be staged at OptimHall, an event venue at Chemin de la Gravière 4 in the Acacias district of Geneva. The building is a former automotive workshop converted into about 1,000 square meters of modular event space, hired in full or room by room, all year round.
Seminars and company events
For conferences and seminars, the venue pairs its large halls with renovated meeting rooms that have daylight, so a plenary in the Main Hall can run alongside breakout sessions in the smaller rooms. Layouts include theater, classroom, U-shape, boardroom and cabaret. Every room has LED lighting on DMX control and a sound system of ten 300-watt speakers with two subwoofers, and a projector, stage, lectern, Wi-Fi and cloakroom are available. Power runs on two 32-amp and two 16-amp three-phase supplies, with space for a generator, and drapes can be hung to divide the space. Company evenings, team building and Christmas parties are part of the offer. The halls have also hosted motor, watch and wine shows and product launches, including a car display in the largest hall. The partner agency Optima Live can take on logistics, technical production, decoration, photographers, caterers, artists and full event management.
Weddings and receptions
Receptions cover standing cocktails, seated dinners, gala evenings, weddings, birthdays and graduation ceremonies. The Main Hall seats 300 for dinner, and with the Studio Hall the venue seats 500 or holds 900 for a cocktail. The team follows the hosts from planning to the event day.

History and setting
The halls occupy a former industrial building once used as an automotive workshop. Daylight enters through the shed roofs of the old workshop. The venue has hosted artists and concerts since 2019.
Getting there
The Acacias district lies close to central Geneva, near the La Praille shopping center, and the venue states that many parking spaces are nearby. Geneva Airport is the nearest airport.
