An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. In Guildford, a town of around 70,000 people in Surrey, the work is planned around the HMO rules for England and the council’s written HMO standards. With students as well as working sharers renting in Guildford, we plan bigger jobs for the gap between academic-year tenancies where we can.

Extensions for extra rooms in Guildford must satisfy national law for England, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- Fire precautions follow a risk assessment; the LACORS Housing – Fire Safety guide (2008) is guidance, not law, but many councils base their standards on it.
