THE ATTIC AFFAIR
An event venue in Zurich that is deliberately different.
COSMO is not a traditional event venue. In the heart of Zurich, close to Lake Zurich, an exclusive event flat awaits you, combining high-quality interior design, privacy and an extraordinary atmosphere.
Instead of a conventional function room, you have a stylishly furnished flat at your exclusive disposal for your event. Spacious interior areas and two private terraces with stunning views over Zurich create a special setting for events that will be remembered for years to come.
BUSINESS EVENTS & MEETINGS
Whether it’s a business meeting, workshop, strategy session or corporate event – COSMO offers an inspiring and personalised setting for productive gatherings away from traditional conference rooms.
PRODUCT LAUNCHES & BRAND EVENTS
COSMO provides a stylish backdrop for product presentations, brand events and exclusive press events. The high-quality interior design and versatile spaces allow for bespoke presentations of your brand.
DINNERS & RECEPTIONS
From an elegant business dinner to an exclusive drinks reception or a personalised networking event: COSMO combines the atmosphere of a private flat with an exceptional view over Zurich.
PHOTO & VIDEO PRODUCTIONS
The carefully designed interiors, natural light and private terraces offer a wide range of possibilities for photo shoots, film productions and high-quality brand content.
TAILOR-MADE & PERSONALISED
The fully equipped kitchen allows for catering and preparation on site. On request, we can assist you in organising bespoke catering solutions through selected partners.
YOUR EVENT. YOUR SETTING.
