Extensions in Merton

Planning, building regs and structural calcs

Householder planning applications in the London borough of Merton are decided by London Borough of Merton. Many London boroughs have extensive conservation areas and Article 4 directions that limit permitted development, so we check your street and the borough's design guidance before we draw anything.
