HMO layout changes across Hertfordshire

In short: 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. In Hertfordshire we survey first, price each item separately and hand over the certificates and photos a council asks for.

The Fire Safety Order 2005 applies to the common parts of HMOs, enforced by the fire and rescue authority.
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.
Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
