What people remember
We had 260 people for dinner in the Grain Hall and it still felt like a room, not a hangar. Selin ran the night like a stage manager.
Ayşe & Kaan OralWedding, September 2025 Two days, 380 attendees, the loft for workshops. The blackout and the rigging points saved our production budget.

Questions
Before you enquire

- How late can we go?
Music until 01:00 indoors and 23:00 on the terrace, guests out by 01:30. We’re by a village, and we’d like to stay welcome there.
- How do we hold a date?
Send an enquiry and we’ll hold the date for seven days, free. A 30% deposit confirms it.
- Is the building accessible?
Every space is step-free or served by the lift; there are two accessible toilets and a hearing loop in the Grain Hall.
