La Roseraie can host off-site seminars, board meetings, training days, team building and daytime private receptions for up to 60 guests standing or 50 seated, with the house and park privatized for the group. The property is a listed 19th-century house with a Belle Époque rock garden at Sains-en-Amiénois, 7 kilometers from the center of Amiens in the Somme.
Seminars and company events
The house is open all year for green seminars, executive committee meetings, training sessions and meetings, as well as general assemblies, product launches, small conferences, cocktails, exhibitions, Christmas parties and retirement events. The whole site is privatized, with direct access to the terraces and the park.
A day or half-day seminar package is offered from 15 participants. It covers the reception room, the park and terraces, equipment and furniture, a welcome coffee, a morning break, lunch, an afternoon break and drinks throughout the day. Lunch can be served hot, as a cold buffet or as a rotisserie meal, and outside on the terrace in good weather. The room can also be hired on its own.
Team building is a strength of the house. La Quête de la Rose, designed with Agence Luminance, sets teams challenges of skill, sensory, cultural and artistic workshops and riddles, for 10 to 40 people over two to four hours, in any season. Themed evenings can be added: casino, quiz, murder party, treasure hunt or wine tasting, along with sports, cooking or art workshops, life-size games and traditional Picardy games.
Weddings and receptions
Private clients can book the house in the daytime for christenings, communions, birthdays, family reunions and lay ceremonies. Guests have access to the terrace and park all year. Hire is available on weekdays or weekends, during the day. Weddings appear among guest reviews on the site, but evening events are not offered.
Rooms and capacities
The reception room covers 60 square meters and opens directly onto the terrace and park. The practical-information page gives 60 standing, 50 seated and 24 in a U-shape; the receptions page gives 45 seated. Equipment includes a video projector, a wall screen of 2.30 by 2.00 meters, Wi-Fi, three microphones, three easels and three flipcharts, plus sound and lighting for receptions. Parking takes up to 50 cars.
Catering
The seminar package includes breaks and lunch. For private receptions, no caterer is imposed, so hosts can bring their own.
History and setting
Bénoni-Joseph Vagniez-Fiquet, an Amiens textile merchant, completed La Roseraie in 1866 as an investment: it was leased to the French state as a gendarmerie until 1886. Around 1890 his younger son turned it into a small château, adding a tower, an observatory and an Art Nouveau rotunda salon. From 1903 his daughter Jeanne Vagniez laid out the Belle Époque park, with rockwork basins, a serpentine stream starting in an artificial grotto, cascades, bridges and a box maze around a gazebo. Greenhouses grew roses for the family houses, which gave the property its name.
In 1940 the house served for three days as the command post of a French artillery officer. The house and park have been listed as a Monument Historique since March 2020. The property belongs to the sixth generation of the Vagniez family, and François Lecomte-Vagniez receives clients himself.
