An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. Bolton is 11 miles north-west of Manchester. We price extensions for extra rooms there against England’s HMO rules and the council’s written HMO standards, so work is planned to the standard an inspection looks for. Bolton has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.
