What local planning policy applies to a drawing package in SM7?

How designation changes a SM7 (Banstead) drawing package: Sutton Council maintains 17 conservation areas, including Cheam Village, Sutton Central, Carshalton Village. Inside any of them a SM7 (Banstead) 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. Carshalton Village sets the tone for SM7 (Banstead) casework.

SM7 (Banstead) permitted development status: there is no borough-wide direction from Sutton Council, so a drawing package at a SM7 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a SM7 (Banstead) sale to argue it later.

The dimensions that certificate is tested against are fixed nationally rather than by any council. Schedule 2, Part 1, Class A of the 2015 permitted development order lets a single-storey rear extension reach 3 m past the original back wall of a semi-detached or terraced house, and 4 m past a detached one; where the extension comes within 2 m of a boundary the eaves are capped at 3 m. An SM7 drawing package is dimensioned to those limits, or deliberately past them with an application behind it.

What SM7 (Banstead) 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 drawing package route in SM7 (Banstead) 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.

Who decides a drawing package on the edge of SM7?

• Merton — adjoining SM7 (Banstead), with 28 conservation areas centred on SW16. A drawing package on the far side of the SM7 (Banstead) line is determined by Merton Council, so the SM7 (Banstead) quote for architectural drawings is checked against Merton guidance before it is issued.
• Croydon — cross the SM7 (Banstead) boundary and Croydon Council takes the drawing package instead, applying 24 conservation areas of its own around CR0. We re-price architectural drawings at the SM7 (Banstead) edge because Croydon policy and Sutton policy rarely align on drawing package depth.
• Kingston upon Thames — adjoining SM7 (Banstead), with 22 conservation areas centred on KT1. A drawing package on the far side of the SM7 (Banstead) line is determined by Kingston Council, so the SM7 (Banstead) quote for architectural drawings is checked against Kingston upon Thames guidance before it is issued.
