About the Chatsworth Square and Portland Square Conservation Area
The Chatsworth Square and Portland Square Conservation Area covers about 19 hectares and was designated by Cumberland Council in 1992. Inside the boundary are 68 listed buildings (5 Grade II*, 63 Grade II). The most significant is 1, Victoria Place, Grade II*. Part of the area lies in flood zone 2, so an extension may need a flood risk assessment.
What changes inside the conservation area
Conservation areas are “Article 2(3) land”. You keep most permitted development rights, but these are removed or tightened.
