Building Regulations Drawings in Holland Park |

An Article 4 Direction applies across Kensington and Chelsea, so check it before assuming Holland Park permitted development survives. The character of Holland Park is the yardstick a RBKC Planning officer measures a scheme against: Victorian villas around the park. Of the 38 conservation areas Kensington and Chelsea designates, Chelsea and Notting Hill are the ones that most often change how a Holland Park project is routed. Designation status for the W11 address is established first.

That mapping of Article 4 directions across Holland Park happens before design, which is what keeps the RBKC Planning route predictable. What the Holland Park building allows is established first; what RBKC Planning allows, second. The borough policy layer over every W11, W14 address is set out on Kensington and Chelsea planning. The Holland Park survey then carries into house extension drawings in Holland Park if the project runs on to construction.

The Holland Park clock does not start until Royal Borough of Kensington and Chelsea validates — one to two weeks. The first visit to Holland Park is a measured survey — every room, every opening, every level change recorded on site.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

Neighbour consultation on a Holland Park case runs 21 days from registration. Holland Park clients receive existing and proposed sheets in one indexed set.

Comments on a Holland Park application are visible on the Royal Borough of Kensington and Chelsea portal. A Holland Park survey takes two to three hours and needs access to every room.

The party wall step is not optional on shared Holland Park walls, and serving late is what stalls sites. Once consent is granted, architectural drawings follows for the W11 property.

Holland Park is characterised by victorian and edwardian villas, concentrated across W11, W14 in the Notting Hill / Holland Park area. Holland Park is not uniform, but the victorian and edwardian villas recurs often enough across W11, W14 that the structural pattern is predictable once measured. Reading that across to Holland Park stock: victorian solid brickwork here drives the Part L strategy and the Part C damp detailing. It is why the Holland Park existing set is measured, not traced. The blocks around Design Museum set the prevailing eaves and ridge lines, and RBKC Planning officers reference that rhythm when assessing height and massing on a Holland Park street.

Digging down in Holland Park runs into policy: RBKC's basement policy (post-2015) limits to single-storey under 50% of garden area; double-storey basements effectively prohibited in residential streets. Survey once, use it for every W11 submission that follows.
