    Variation of condition 4 (Trees) on Planning Permission 25/1665/FUL (Proposed front porch, two storey side extension and alterations to fenestration. Addition of render.) Submitted drawing clearly plots the Root Protection Areas (RPAs) for the nearby trees. To confirm that the footprint of our proposed extension sits entirely outside of these zones. There is no intersection with or encroachment into the line of protection, meaning the design respects the constraints and the root systems will remain undisturbed.
