The Great Barn at Headstone Manor is hired for weddings, Christmas parties and corporate events. It takes up to 250 guests for a ceremony and up to 200 for an evening reception, and hirers have exclusive use of the barn and the grassland behind it. The barn stands in the grounds of Headstone Manor and Museum, in Harrow, at Pinner View.
Seminars and company events
The venue promotes the Great Barn for corporate events and Christmas parties. A PA system and a wireless microphone are provided, which helps for speeches, presentations and award evenings. Tables and chairs are available, while linen is not included. Access starts at 10:00 on the day of the event, which gives time to set up, and extra hours may be added for an additional charge. The barn can be used until 23:00 from Monday to Wednesday and until 23:55 from Thursday to Sunday, and suppliers and guests must leave by closing time. The Manor House, the Granary Learning Centre and the museum grounds stay open to the public from Tuesday to Sunday, 10:00 to 16:00, so daytime events should plan for visitors in the grounds.
Weddings and receptions
The Great Barn is an approved location for civil weddings and civil partnerships. Notice of marriage goes through the local registry office at least 15 days before the ceremony, and the couple books the registrar once the date is reserved. The licence carries noise conditions, shared with any DJ or band. Candles are allowed in suitable holders, confetti must be fully biodegradable, and helium balloons and fireworks are not allowed. Wedding cars may use the museum grounds for drop-off, photographs and pick-up only. Dogs are welcome on the grounds but not inside the buildings, except guide dogs.
Rooms and capacities
The Great Barn is the main space. It was built in 1506 and is Grade II* listed. Capacity is 250 for a ceremony and 200 for an evening reception. The hire includes exclusive use of the rear grassland, which can host a barbecue or a hog roast. The venue publishes a floor plan and a brochure for planning. The barn is easy to reach on foot, with disabled toilets, a baby changing area and highchairs.
Catering
The barn has a finishing kitchen only. Food preparation and cooking must be done off site or in a mobile kitchen in the outdoor space at the rear. The venue keeps a preferred caterer list and works with the organizer's own caterer, who must supply a risk assessment, a food hygiene certificate and public liability insurance. On the grassland, only gas or electric fires are allowed for barbecues and hog roasts, not coal or wood. The bar closes at 22:00 from Monday to Wednesday and at 23:00 from Thursday to Sunday.
History and setting
Headstone Manor and Museum includes the Great Barn and three further listed historic buildings, landscaped gardens and a moat from the 14th century. Photography is not permitted inside the Manor House, the Granary Learning Centre or the Small Barn.
