An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. In Lancaster, a town of around 45,000 people in Lancashire, the work is planned around the HMO rules for England and the council’s written HMO standards. Lancaster has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.
