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 Penarth we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately.
