House Extension Drawings in Park Royal |

An Article 4 Direction applies across Ealing, so check it before assuming Park Royal permitted development survives. The Park Royal setting is industrial fringe, new residential, which shapes what passes near Park Royal station. Park Royal sits close enough to Pitshanger that designation should be checked at the outset, not after design. That check comes before anything else on a Park Royal job.

The Park Royal Article 4 position is established at survey, before design. Rear wall, floor levels and the Park Royal station roofline are the three Park Royal constraints. The borough policy layer over every NW10 address is set out on Ealing planning. The Park Royal survey then carries into architectural drawings in Park Royal if the project runs on to construction.

A Park Royal application is not live until London Borough of Ealing validates it, which takes one to two weeks on a complete pack. Nothing is drawn for a NW10 address until the existing building is measured.

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 Park Royal case runs 21 days from registration. Output for Park Royal: dimensioned PDFs at the scales the authority specifies.

Speaking to NW10 neighbours before submission avoids most of it. A Park Royal measured survey captures the roof structure as well as the plan.

Most Park Royal terraces share a flank wall, so party wall notices apply. Once consent is granted, planning permission follows for the NW10 property.

Park Royal is characterised by modern apartments, post-war estates, concentrated across NW10 in the Willesden / Harlesden / Kensal Green area. Park Royal rewards a survey-first approach: the modern apartments rarely matches its own original drawings. On NW10 plots specifically, post-war houses on these estates often sit under an estate management scheme, which can remove permitted development independently of any Article 4 direction. On Ealing stock it changes the party wall position. Height on a Park Royal proposal is measured against its neighbours, not against a policy number; the Park Royal station terraces set that datum.

Ealing sets no special basement rule, so a Park Royal lower-ground scheme stands or falls on the engineering and the neighbours. If a Park Royal project extends into building regulations drawings for NW10 properties or loft conversion drawings, the survey is already done.

What the Park Royal drawing pack contains

Here is what a NW10 instruction actually produces.

Local landmarks that shape a Park Royal application

• Ayresome Park — side returns where the 45-degree amenity test decides how far a Ayresome Park extension goes.
• Hanger Hill — roof profiles that set the ridge datum Ealing Council measures a Hanger Hill dormer against.
• Stonebridge Park — shared flank walls, so Stonebridge Park party structure notices go out before work starts.
• Park Royal station — massing on adjoining NW10 plots is tested against it.
• Central Middlesex Hospital — sightlines from here are part of the Ealing Council character assessment.
• Old Oak Common — it fixes the local datum a Park Royal roof extension is judged against.
