Full Venue at Oneforty Harrow
About this space
THE FRONT ROOM — 6m x 5m
A light, airy indoor space that's yours to style however you like. From minimalist setups to full décor transformations, this space adapts to your event. Acts as the main bar hub, perfect for buffet setups and mingling once the garden winds down for the evening.
---
THE SECRET GARDEN — 12m x 6m (72 sqm)
A sun-drenched outdoor patio framed by greenery — genuinely rare to find in Harrow. Dress it up for a drinks reception, a relaxed afternoon celebration, or an early evening mixer. Note: the garden closes at 10:00 PM as part of our neighbourhood policy, so parties close to our maximum capacity work best as afternoon-into-evening events.
---
THE CAFÉ-BAR
A fully operational licensed bar at the heart of the venue. Whether you choose our staffed Bespoke Bar package or bring your own drinks under a dry hire package, the bar — including all glassware, ice, and refrigeration — is part of every booking. Light, airy, and easy to style around your event's theme.
