About

Join us for a housewarming at Treo House.


Treo House is all about authentic and worthwhile conversation. Our welcome nights are designed to help you to meet other members, skip the small talk and connect with people who share your values. This is a small group gathering, for up to 8 people, which will take place in our cosy private sofa area.


Event details:

  • The event will start at 6pm and will consist of 2 hours of guided discussion, focussed on getting to know other members and experiencing Treo House.

  • Delicious homemade snacks, cold drinks and tea will be provided. We also have an awesome selection of craft beers and biodynamic wines for purchase.

  • This event will be held inside, there is no dress-code.

  • Please arrive from 5:45pm, for a prompt 6:00pm start.

  • There are multiple dates for these welcome evenings. Each will follow a similar structure so it's advised to only attend one.

  • The event will be hosted by the founder of Treo House, Gemma Lannon.
