Colzium House has one main hall, which is situated on the first floor and can hold a maximum of 100 people for a dinner dance or disco. There is a bar and a stage at the rear of the hall. There are also two rooms available for hire on the ground floor, both of which can cater for up to 40 people. Each room in the house overlooks the beautiful surrounding gardens.

Kitchen facilities complement main hall requirements, and are ideal for catering or for hired caterers to work from. They can also be used simply for heating food provided by guests. There is a large free-standing fridge available if required.
