The Article 4 Directions in Ipswich are applied within the boundaries of existing conservation areas and enhance the protection offered by the conservation area designations. In most instances they correspond to the full extent of the conservation area boundary, although in two cases (Bolton Lane & The Walk) the Article 4 area is a smaller area within the conservation area, covering a specific building group (in the case of The Walk the Article 4 designation only applies to frontages and the paving).
