In most cases, residential loft conversions across the Swale borough fall under Permitted Development rights. This means you generally do not need full planning permission as long as the additional roof volume doesn’t exceed 40 cubic metres for terraced homes, or 50 cubic metres for semi-detached and detached houses. However, full planning permission is required if you live in a conservation area, a listed building, or plan to alter the front-facing roofline. Our in-house design team handles the entire assessment and applies for a Lawful Development Certificate on your behalf.
