How the guidance is built
The page combines the English planning system baseline with local authority context and rule-specific evidence such as measured thresholds, heritage sensitivity, planning history and site constraints.
When to stop relying on broad guidance
Escalate once the answer depends on a tight measurement, a sensitive site, or an interpretation you would not want to defend after drawings or applications are in motion.
Safest formal next step
Use a lawful development certificate when the scheme appears lawful but this rule is carrying too much of the risk. Use pre-application advice when local judgement or policy weight is likely to matter more than the headline rule.
