What local planning policy applies to a garage conversion in Sutton?

Sutton conservation designations: there are 17 across Sutton Council, Cheam Village, Sutton Central, Carshalton Village among them. Designation costs a Sutton owner the permitted-development route: a garage conversion then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Cheam Village is the Sutton designation that most often changes a garage conversion design.

Article 4 and your Sutton garage conversion: Sutton Council has made no borough-wide direction, so permitted development for a garage conversion in Sutton generally survives outside Sutton conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a KT4 owner records that a garage conversion was lawful.

What Sutton is built from: 1930s semi-detached dominates; Edwardian terraces and villas in Sutton central; Victorian cottages in Carshalton; post-war in Hackbridge. Outer south London suburban; generally permissive; Carshalton and Cheam conservation areas add heritage in pockets. That mix decides the garage conversion route in Sutton more than the postcode does, and it is what a Sutton Council case officer reads first. A householder application costs £548 paid to Sutton Council direct, with 8 weeks to a decision once validated.

• Croydon — cross the Sutton boundary and Croydon Council takes the garage conversion instead, applying 24 conservation areas of its own around CR0. We re-price garage conversions at the Sutton edge because Croydon policy and Sutton policy rarely align on garage conversion depth.
