An HMO loft conversion adds one or two letting rooms, often with an ensuite, in the roof space. For a house in Stratford we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately. With students as well as working sharers renting in Stratford, we plan bigger jobs for the gap between academic-year tenancies where we can.

Which rules apply in Stratford?
Loft conversions for extra rooms in Stratford 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.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
