Separation distances for windows overlooking adjacent properties
Windows overlooking adjacent properties require minimum separation distances of 20 metres between facing windows of main habitable rooms, or 10 metres where facing blank gable walls or non-habitable room windows. Level changes may affect required distances.
Windows in elevations that overlook adjacent properties will not normally be approved unless there is adequate separation distance between the host dwelling and its neighbours. In general, a separation of no less than 20 metres should be maintained between facing windows of the main habitable rooms (i.e. bedrooms, living rooms, dining rooms or kitchens). Where windows face a blank gable wall or a wall with only windows to non-habitable rooms (e.g. utility room or bathrooms), a separation distance of no less than 10 metres should be maintained. Additionally, changes in the levels may result in an increase or decrease in the separation distances required.
