Planning World

Planning World provides planning applications, architectural drawings, surveys, and compliance reports tailored specifically to the London Borough of Barnet — where strict design guidance, extensive conservation areas, and prescriptive rules on extensions and roof alterations make borough-specific expertise essential to securing first-time approval.
Barnet is one of London’s largest boroughs, with a predominantly suburban character and some of the most detailed local design guidance in North London. The council frequently rejects proposals that fail to respect character, scale, or amenity standards — particularly for rear and side extensions, loft conversions, and backland development — making Barnet one of the more challenging London boroughs to navigate without professional support that understands its specific validation requirements and officer expectations.
