An HMO loft conversion adds one or two letting rooms, often with an ensuite, in the roof space. In Birmingham, a city of over a million people in West Midlands, the work is planned around the HMO rules for England and the council’s written HMO standards. Birmingham has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.
