If you want a cathedral or vaulted ceiling, you will need to look carefully at the roof structure your builder is proposing to achieve the vaulted roof space. In this video you will see the various options in action using a timber model of a vaulted roof. You will see the effect on the supporting walls for an unsupported vaulted roof, collar tied roof, and what effect it has if you have the collar tie at 1/3 or 2/3 height to stop roof spread.
