An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. Landlords in Egham (TW20) usually come to us with a council letter, a fire risk assessment or a house they have just bought. We price from whichever you have. With students as well as working sharers renting in Egham, we plan bigger jobs for the gap between academic-year tenancies where we can.

Which rules apply in Egham?
Extensions for extra rooms in Egham 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.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
- Smoke alarms on every storey with living accommodation and CO alarms by fixed combustion appliances (other than gas cookers) are required by law.
- National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
