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. We carry this out across Greater London, priced against the HMO rules for England and the council’s own standards.

- 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.
- The Fire Safety Order 2005 applies to the common parts of HMOs, enforced by the fire and rescue authority.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
Councils in England can add additional licensing and Article 4 directions on top of the national rules. Check the council’s website for the exact address before you buy or start work.
