Separation distances between facing windows in residential development
Minimum separation distances must be maintained between facing windows of main habitable rooms, with different requirements depending on whether windows face habitable or non-habitable rooms, and accounting for changes in ground levels.
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.
