Description

A two-storey rear extension can be built under Permitted Development rights without needing prior notification. It’s essential to remember that this extension must not include any windows on the side elevation’s wall or roof slope for the upper floors. Additionally, it should take up less than 50% of the original house’s width and less than 50% of the land surrounding it. The term “original” refers to the property’s most recent state when it was constructed or, for properties built before 1948, its condition as of July 1, 1948. To comply with regulations, the extension should use materials that match the existing house and have eaves and a ridge height that does not exceed that of the current structure. For terraced homes, the extension’s height must not surpass 3.5 meters above the height of the adjacent terrace. It’s also important to note that single-storey homes cannot take advantage of this type of extension. Projection Limit: It must not extend more than 3 metres beyond the original rear wall of the house. Boundary Distance: It must be at least 7 metres away from the rear boundary. Height: The eaves and ridge heights must not be higher than those of the existing house. Side Windows: Any upper-floor windows in a side wall must be obscure-glazed and non-opening (unless the openable part is more than 1.7 metres above the floor).
