Local planning context
Planning in Kensington and Chelsea
The Royal Borough of Kensington and Chelsea receives a large volume of householder applications each year. The ones that succeed first time are typically those that have anticipated the validation requirements and addressed the most common officer questions before submission.
Pre-application discussions with Royal Borough of Kensington and Chelsea planning officers are available for most householder proposals in Kensington and Chelsea and are often worthwhile for larger or more complex projects. The feedback received at pre-application stage can significantly improve an application before it is submitted, reducing the risk of conditions or refusal.
Permitted development limits in Kensington and Chelsea are fixed nationally, but their application to a specific property can be complex: cumulative extensions, loft additions already made, and any prior consents all count. We carry out a permitted development assessment as part of the initial project briefing so the route is confirmed before design work begins.

Conservation Areas in Kensington and Chelsea
Kensington and Chelsea has 39 conservation areas designated under the Planning (Listed Buildings and Conservation Areas) Act 1990. These areas — including Oxford Gardens, Norland, Ladbroke, Pembridge — impose additional controls on development and require proposals to demonstrate how they preserve or enhance local character.
Conservation area designation in Kensington and Chelsea does not mean that development is not possible — it means that the design, materials, and overall approach need to demonstrate that the area's character is preserved or enhanced. Most extension and loft conversion types are achievable with the right design treatment.
Within conservation areas in Kensington and Chelsea, Royal Borough of Kensington and Chelsea planners assess householder applications against the Characterisation Studies or Design Guides published for each area. A well-referenced proposal that acknowledges these documents typically progresses more smoothly than one that does not.

Planning Drawings
Planning drawings for Kensington and Chelsea projects must meet the validation requirements set by Royal Borough of Kensington and Chelsea: correct scales, north points, appropriate level of detail, and coordination between plans and elevations. A package that fails on a technical validation point costs time and delays the clock.
Our planning drawing packages for Kensington and Chelsea properties include all the documents required for a householder application: site location plan (1:1250 or 1:2500), block plan (1:500), existing floor plans and elevations, and proposed floor plans and elevations — drawn to scale and clearly annotated.
The drawings are prepared in the context of the specific property and the local character. In conservation-sensitive parts of Kensington and Chelsea, this means addressing materials, window proportions, and roofline changes explicitly in the elevations and in any supporting design note.

Our Process for Kensington and Chelsea Projects
After planning permission is granted, building regulation drawings are prepared and submitted to Royal Borough of Kensington and Chelsea's building control department (or an approved inspector), initiating a parallel approval process before work begins on site.

All projects in Kensington and Chelsea begin with a free consultation call where we discuss the brief, the property, and the likely planning route. We then issue a detailed fixed-fee proposal before any survey or design work begins, so there are no surprises on costs.

Housing Stock and Local Character in Kensington and Chelsea
Kensington and Chelsea is the most densely listed borough in England, characterised by grand stucco-fronted Victorian townhouses, garden squares, and world-class architectural set pieces. This character shapes what planning applications are likely to succeed and how they need to be presented to Royal Borough of Kensington and Chelsea.
The residential stock in Kensington and Chelsea consists principally of Victorian and early-Victorian terraces, stucco-fronted townhouses in Kensington and Notting Hill, mews properties, and mansion flats — almost entirely within conservation areas. Understanding how the existing building type responds to extension or alteration is the starting point for any design brief — it defines the structural approach, the planning sensitivities, and the opportunities for the project.
Key areas within Kensington and Chelsea where we regularly work include Kensington, Chelsea, Notting Hill, Knightsbridge. Each of these areas has its own micro-character, planning history, and in some cases specific conservation area or Article 4 designations that affect what is achievable on any given street.
Service information
Planning Drawings — Further Information
Planning drawings for Kensington and Chelsea are submitted through the Planning Portal and must meet specific technical requirements: correct file format (PDF), maximum file size per document, and specific naming conventions. Our submission process includes a final technical check against Royal Borough of Kensington and Chelsea's validation requirements before the application is lodged.
We retain all project drawings in our document management system for the full project period and beyond. If Royal Borough of Kensington and Chelsea requests additional copies, amendments, or older versions during the application process, we can respond immediately without asking clients to locate and supply historic information.
Service information
Building Regulations in Kensington and Chelsea
Building regulations apply to most construction works in Kensington and Chelsea regardless of planning permission status. Extensions, loft conversions, structural alterations, and changes to drainage or electrics all require compliance with the relevant Parts of the Building Regulations, verified by Royal Borough of Kensington and Chelsea building control or a registered building control approver.
Building regulation approval in Kensington and Chelsea runs in parallel to planning consent — they are two separate legal processes. We manage both for clients who wish to use Crown Architecture for the full project, or we can work alongside a client's own building contractor or structural engineer where preferred.
Common questions
Planning Drawings in Kensington and Chelsea — frequently asked questions
Answers to the planning, design, and regulatory questions we are most often asked about Planning Drawings in Kensington and Chelsea.
How long does it take to prepare planning drawings for a Kensington and Chelsea extension?
For a typical householder extension in Kensington and Chelsea, we carry out a measured survey of the property and then prepare the planning drawing package within two to three weeks. More complex projects — involving conservation areas, listed building curtilages, or multi-storey proposals — may take three to five weeks. We agree a programme at the start so you know when the application will be ready to submit.
What scale do planning drawings need to be in Kensington and Chelsea?
Royal Borough of Kensington and Chelsea in Kensington and Chelsea requires drawings at recognised scales: typically 1:100 or 1:50 for floor plans and elevations, 1:200 for site plans, and 1:500 for block plans. All drawings must carry a north point, a scale bar, a drawing number, and a clear revision history. Drawings submitted without these details may be invalidated.
Do the drawings need to be prepared by an architect?
Drawings submitted to Royal Borough of Kensington and Chelsea do not legally have to be prepared by a registered architect, but professionally prepared drawings are significantly more likely to meet the validation requirements first time and to present the proposal persuasively. For most householder projects in Kensington and Chelsea, using a professional draughtsperson or architect is both faster and more cost-effective in the medium term.
What drawings are required for a planning application in Kensington and Chelsea?
Royal Borough of Kensington and Chelsea in Kensington and Chelsea requires, at minimum: an OS-based site location plan at 1:1250 or 1:2500 (typically sourced from Ordnance Survey); a block plan showing the site boundaries at 1:500; and existing and proposed floor plans and elevations at 1:50 or 1:100. Additional documents — sections, roof plans, design-and-access statements — are required depending on the nature of the works and whether a conservation area is involved.
What is a design and access statement and do I need one in Kensington and Chelsea?
A design and access statement (DAS) is required by Royal Borough of Kensington and Chelsea for householder applications in conservation areas and for listed building consent. It explains the design rationale and how the proposal responds to the local character, the heritage asset, and the accessibility requirements. We prepare DAS documents as part of the planning package where Royal Borough of Kensington and Chelsea's requirements mandate one.
Do planning drawings show interior details?
Planning drawings do not generally show interior fitout details — they focus on the external appearance of the building and the relationship of the proposal to its plot and neighbours. Internal layouts are shown in floor plans to the extent needed to demonstrate the nature and scale of the works, but room-by-room interior design detail is a building regulation and interior design matter rather than a planning one.
What happens if Royal Borough of Kensington and Chelsea asks for additional drawings after submission?
After an application is registered in Kensington and Chelsea, the case officer may request additional information or revised drawings, particularly if there is a heritage or design concern. We handle all these requests as part of the service, preparing amended drawings and uploading the revised package to the Planning Portal without additional charge for reasonable single-round amendments.
Do you prepare the location plan as part of the planning drawings?
Yes. Our planning drawing packages for Kensington and Chelsea include an Ordnance Survey-based site location plan with the property boundary marked in red and any adjacent land in the applicant's control marked in blue — meeting Royal Borough of Kensington and Chelsea's standard requirements. The location plan is prepared at 1:1250 for urban areas.
Do I need separate drawings for listed building consent in Kensington and Chelsea?
If a property is listed and works affect the listed building itself (not just the garden or boundary), listed building consent is required separately from planning permission in Kensington and Chelsea. The drawings for a listed building consent application must demonstrate how the works preserve or enhance the special interest of the listed building and are assessed by Royal Borough of Kensington and Chelsea's heritage officers. We include heritage impact notes in the drawing package for listed building applications.
Can planning drawings be used for building regulations too?
Planning drawings are prepared to a level of detail appropriate for planning assessment — they show form, massing, and appearance but not full construction detail. Building regulation drawings contain significantly more technical information: structural specification, insulation details, drainage, fire separation, and accessibility compliance. We prepare planning and building regulation drawings as coordinated packages, with the planning set forming the design foundation for the detailed technical set.
Who is the planning authority for Kensington and Chelsea?
The planning authority for Kensington and Chelsea is Royal Borough of Kensington and Chelsea. All planning applications for residential and commercial developments in Kensington and Chelsea are submitted to and determined by Royal Borough of Kensington and Chelsea, which also provides pre-application advice and manages the planning enforcement function for the borough.
What types of development need planning permission in Kensington and Chelsea?
In Kensington and Chelsea, planning permission is required for: new buildings; extensions that exceed the permitted development limits; changes of use (e.g. from residential to commercial); demolition of protected structures; and any works that affect a listed building or its curtilage. Smaller extensions, loft conversions within volume limits, and outbuildings within the curtilage may fall within permitted development, but constraints apply in conservation areas and Article 4 zones.
