A house to HMO conversion turns a single-family home into a house in multiple occupation: a shared home for unrelated people with private bedrooms and shared kitchen or bathroom space. For a house in Holloway we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately.

Which rules apply in Holloway?
House to HMO conversion in Holloway 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:
- Mandatory HMO licence for 5 or more people in 2 or more households (since October 2018); councils can add additional licensing for smaller HMOs.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
- National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
