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. In Windsor, a town of about 32,000 people in Berkshire, the work is planned around the HMO rules for England and the council’s written HMO standards.
