A commercial to HMO conversion turns space that was never a home, such as upper floors over shops or small office buildings, into shared accommodation. For a house in Harrow we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately.

Questions about commercial and above-shop to HMO in Harrow
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.
Which postcodes in Harrow do you work in?
All of them, including HA1, HA2 and HA3, and the surrounding parts of Greater London.
Where do I check the HMO rules for an address in Harrow?
With the local council for the address. 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.
