Questions about commercial and above-shop to HMO in Northamptonshire
What about the shop below?
The homes above must be separated from the commercial unit by fire-resisting construction, and the escape route must not pass through the shop. We design the separation as part of the building control application.
Can offices be converted to an HMO without planning?
Some office-to-home changes have permitted development rights in England, but those rights generally create self-contained flats, and HMO use usually needs its own consent. We work from your planning position and flag anything that needs checking.

Yes, across the whole of Northamptonshire, including Northampton, Corby, Kettering.
