An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. Canterbury is 54 miles east of London. 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. With students as well as working sharers renting in Canterbury, we plan bigger jobs for the gap between academic-year tenancies where we can.
