Core Refusal Reason

- The as-built rear dormer, while larger than previously permitted, is consistent with the evolving pattern of roof alterations in the Riverwood estate and is not visually dominant from the public realm.
- The development does not result in excessive overlooking or overbearance due to the site's orientation and the presence of similar modifications on neighboring properties.
- The installation of Velux windows on the front roof plane is considered appropriate and aligned with updated planning implementation policies that support homeowners expanding their living spaces.
