The Laird's Hall, the largest of Culcreuch's public rooms, covers the entire first floor of the tower, which is the oldest part of the building. This was the great hall of the castle, and is now beautifully decorated and furnished with period antiques. It's ideal for formal banquets or a range of social and corporate events.

The Drawing Room, overlooking the loch, acts as the resident's lounge, a quiet area for reading, relaxing, writing postcards or for a relaxed morning coffee. The Carved Hall at the entrance to the Castle is often used for receiving guests in conjunction with events held on the front lawn. Galbraith Hall, originally the stables, retains its stone walls and has a less formal feel than the main house. This is the scene of larger banquets and dances.
