In short: Lambeth applications are submitted through the national Planning Portal and tracked on Lambeth Council's online planning register. Lambeth has many conservation areas across Brixton, Clapham, Kennington, Stockwell and Streatham, plus policies on basements, roof extensions and protecting family homes, so check the Lambeth Local Plan and design guidance early.
