How do conservation areas and Article 4 affect a drawing package in W1J?

Conservation areas covering W1J (Mayfair): Westminster City Council runs 56, and Marylebone, Pimlico, Soho are the ones W1J (Mayfair) owners meet most. A drawing package inside a W1J (Mayfair) conservation area loses permitted development, so the W1J (Mayfair) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In St John's Wood a drawing package is judged on the street elevation first.

What Article 4 removes near W1J (Mayfair): Multiple Article 4 Directions — office-to-residential restrictions, HMO conversions, retail to residential in shopping zones. Before pricing a drawing package we check whether the W1J address is inside the mapped area, because Westminster City Council draws the W1J (Mayfair) boundary street by street rather than across the whole of W1J (Mayfair).

Digging below a W1J (Mayfair) property: Westminster basement policy restricts to single-storey, typically under 50% of rear garden footprint; lightwells and rooflights strictly controlled in conservation areas. Where a drawing package in W1J (Mayfair) involves excavation that is read beside the Party Wall etc. Act 1996, which needs two months notice for a W1J (Mayfair) dig within 3 m of a neighbour, and Westminster City Council expects the W1J ground conditions addressed in the application.

What W1J (Mayfair) is built from: Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density. Heritage-first planning approach; listed buildings on almost every street; basement and rear extension policies particularly strict. That mix decides the drawing package route in W1J (Mayfair) more than the postcode does, and it is what a Westminster City Council case officer reads first. A householder application costs £548 paid to Westminster City Council direct, with 8 weeks to a decision once validated.

Who decides a drawing package on the edge of W1J?

• Camden — the Camden boundary runs against Westminster, so a drawing package a street from W1J (Mayfair) is decided by Camden Council instead. Camden runs 40 conservation areas across NW1 and its neighbours, which is why architectural drawings priced for W1J (Mayfair) are re-checked against Camden policy whenever the W1J (Mayfair) address sits on that edge.
• Kensington and Chelsea — cross the W1J (Mayfair) boundary and RBKC Planning takes the drawing package instead, applying 38 conservation areas of its own around SW1. We re-price architectural drawings at the W1J (Mayfair) edge because Kensington and Chelsea policy and Westminster policy rarely align on drawing package depth.
• Wandsworth — the Wandsworth boundary runs against Westminster, so a drawing package a street from W1J (Mayfair) is decided by Wandsworth Council instead. Wandsworth runs 45 conservation areas across SW8 and its neighbours, which is why architectural drawings priced for W1J (Mayfair) are re-checked against Wandsworth policy whenever the W1J (Mayfair) address sits on that edge.
• Lambeth — adjoining W1J (Mayfair), with 64 conservation areas centred on SE1. A drawing package on the far side of the W1J (Mayfair) line is determined by Lambeth Council, so the W1J (Mayfair) quote for architectural drawings is checked against Lambeth guidance before it is issued.
