How do conservation areas and Article 4 affect a drawing package in SM4?

How designation changes a SM4 (Morden) drawing package: Merton Council maintains 28 conservation areas, including Wimbledon Village, John Innes, Mitcham Cricket Green. Inside any of them a SM4 (Morden) drawing package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Wimbledon Village sets the tone for SM4 (Morden) casework.

SM4 (Morden) permitted development status: there is no borough-wide direction from Merton Council, so a drawing package at a SM4 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a SM4 (Morden) sale to argue it later.

What SM4 (Morden) is built from: Victorian villas in Wimbledon; Edwardian terraces in Tooting and Colliers Wood; 1930s semi-detached in Morden and Raynes Park; post-war flats in Mitcham. Wimbledon is heavily conservation-controlled; outer Merton (Morden, Mitcham) is permissive. That mix decides the drawing package route in SM4 (Morden) more than the postcode does, and it is what a Merton Council case officer reads first. A householder application costs £548 paid to Merton Council direct, with 8 weeks to a decision once validated.
