House Extensions in Camberwell — what to expect

Camberwell's Victorian and Georgian terraces typically have moderate rear garden depths. Ground floor rear extensions at 3–5m are the most common type, creating open-plan kitchen-diner space. Side return extensions suit end-of-terrace properties in the wider residential streets. Some Georgian properties near Camberwell Green sit within conservation areas requiring additional planning attention.

Camberwell property types
