The Terex Corporation conference will be the first corporate event to be held at Mythe Barn since it launched for meetings and events in September.
Terex Corporation will bring 120 delegates from across the UK and Europe to the site for the one-day event.
The conference, organised by Clearwater Events, will see delegates from Terex attend meetings and seminar sessions. The event will also see Terex unveil its latest new plant machinery.
Mythe Barn director Joanna Garland said: "We are delighted to be hosting the Terex event. They wanted a venue that had both indoor and outside space so it is great that we can showcase the flexibility of Mythe Barn.
"This is our first big piece of business since we launched in September for meetings and events, and is great recognition for the hard work we have put in to be winning new business so quickly."
The venue – which features three event spaces – opened in May this year.
Clearwater Events managing director Stephen Morton-Prior added: "We are delighted to be using Mythe Barn for this prestigious client event. The venue has a perfect blend of flexible meeting space combined with outdoor space and outbuildings, which make it perfect for an experiential event of this type."
