An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. In Bournemouth, a place of roughly 160,000 people in Dorset, the work is planned around the HMO rules for England and the council’s written HMO standards. Bournemouth has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.

Which rules apply in Bournemouth?
The rules below are the England-wide position for this kind of work. Councils add their own standards and schemes on top, so we always check the address in Bournemouth before we price.
- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
- 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.
- National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
