Large Houses for 20 Guests in the UK

Organising accommodation for a group this size is one of the more complex planning challenges any group faces. The simplest, most social, and often best-value solution is to book a single large house on an exclusive-use basis — meaning the entire property is yours, with no other guests sharing the space.

Houses at this size typically offer around 9–10 bedrooms across multiple floors, large dining tables seating everyone at once, and several living spaces including lounges, snugs, and conservatories. Some properties at this size feature a private hot tub, games room, or cinema room — each listing shows exactly which amenities are included.

A group this size is a popular one for big birthday celebrations — combining close friends and family for a landmark 40th or 50th. It's equally well-suited to multi-generational family holidays where grandparents, adult children, and grandchildren come together, with separate bedrooms giving each family their own space while shared areas bring everyone together. For corporate retreats, 20 is the ideal size for a full team away-day with workshops, dinners, and informal strategy sessions in an inspiring private setting.

Group Escape Houses features properties across the UK suited to groups this size — from grand manor houses in the Cotswolds to converted farm estates in Cornwall, lakeside retreats in the Lake District, and coastal houses in Devon and Sussex. Each property is listed by its owner, who you'll contact directly to arrange your booking.
