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 Winchester we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately. Winchester has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.
