Housing is so unaffordable that some are forced to share a home with more people than there are beds.

A new study into share-room housing has found that some people are sharing rooms that contain multiple beds, and each bed may have several occupants who sleep in shifts. This practice, known as hot bedding, brings considerable health and safety risks.

Some tenants are international students or those working on temporary migrant visas, raising concerns about how aware tenants are of their rights, and how they can get help if they're evicted, assaulted or faced with rent rises.
