How to Read a Barn Before You Book It

Every barn photographs well in July. The questions worth asking are the ones the tour does not cover.
What the Walkthrough Skips
You will be shown the beams, the light through the big doors and where the band sets up. What you want to know is where the power comes from, how many toilets there actually are, and what happens to the field between the car park and the door after two days of rain.
Ask to see it on a weekday in the off season. A barn in February with the doors shut and no styling is the honest version, and the ones that still feel good are the ones worth booking.
The Numbers That Bite
Capacity quoted for a standing drinks reception is not capacity for a seated dinner, and neither is capacity once you have added a dance floor and a band. Get the seated number in writing with a plan showing round tables, not long trestles, because trestles flatter the count.
Then ask about the curfew. A rural venue with neighbours often has an amplified-music cut-off far earlier than the bar closing time, and that single line changes the shape of the whole evening.
Access and the Bits Nobody Photographs
Suppliers need to get a van to the door. Caterers need somewhere to work that is not the same room as your guests. Bands need parking and a place to change. If the answer to all three is a vague gesture at a gateway, budget for the problem.
And find out who clears up, when, and whether you are paying for it. A surprising number of barn bookings end with the couple's parents stacking chairs at midnight.
