HMO layout reconfiguration changes the internal plan of a shared house so the rooms, kitchens and bathrooms work together: moving or adding walls, splitting oversized rooms, merging undersized ones, or moving the kitchen off the escape route. Landlords in Carshalton (CR4, SM5 and SM6) 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.

Which rules apply in Carshalton?
Layout changes and room reconfiguration in Carshalton 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:
- Licensed HMOs must meet national minimum bedroom sizes: 6.51 m² for one person aged 10 or over, 10.22 m² for two, and 4.64 m² for a child under 10.
- Smoke alarms on every storey with living accommodation and CO alarms by fixed combustion appliances (other than gas cookers) are required by law.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
- Council standards often step up at 5 and 6 sharers, for example a separate WC at 5 and a second bathroom from 6.
