The warm season invites freedom. To respond to this desire to escape, Portes des Iris and its partners offer exceptional outdoor reception solutions. Discover how to transform Terrasse de Collonges into a luminous structure, offering the prestige of a historic setting and the magic of an outdoor event. One of the few sites where anything is possible, thanks to a fully privatizable venue, easy access, modern infrastructure, and recognized experience in high-end events.
At Portes des Iris, this setup is made possible thanks to magnificent outdoor spaces that offer a refined setting, open to nature and the famous Gardens of the Château de Vullierens. Setting up a tent or orangery allows you to create a dedicated, intimate space, particularly appreciated in spring and summer, when the landscape becomes an integral part of your guests’ experience.

Orangeries or semi-enclosed structures offer a perfect balance between outdoors and indoors. They allow you to fully enjoy the landscape while providing comfort and protection. This solution is particularly appealing to those who are looking for a sleek and bright aesthetic without sacrificing logistical security in the case of unpredictable weather.

The size of the structure depends on the type of reception planned. As a guide:
1 m² per person for a seated reception.
0,5 m² per person for a standing cocktail reception.
1,5 m² per person if the entire event (aperitif and dinner) takes place under the tent.
In summer, depending on the conditions of the ground, some receptions can be held without flooring. However, damp ground can complicate matters; the use of suitable furniture is therefore essential, and laying parquet flooring is strongly recommended for dance areas and for the comfort of your guests.
Creating a temporary structure is a major project, comparable to designing a custom-built private space. The budget for this transformation reflects this total freedom: expect to pay around CHF 30,000 for an elegant configuration, and up to CHF 200,000 for exceptional fittings including silk canopies, fine flooring, and dramatic lighting.
Choosing this option means treating yourself to a venue that exists for no one else, only for that day. This amount covers the architecture of the tent as well as all the necessary logistics, because under the tent, every detail must be anticipated: bars, temporary kitchens, luxury bathrooms, and technical circulation areas.
Such a deployment requires rigorous preparation. Our service providers manage all logistics for you, including set-up and dismantling times, which can immobilize the site for several days depending on the scale of the project. This advance preparation guarantees a smooth reception and total safety, while complying with current regulations, particularly with regard to noise pollution.
Portes des Iris team is at your disposal to assist you and put you in touch with specialized partners to ensure the success of your event and offer you an experience that matches the exceptional nature of our venue.
