Planning Drawings in Chiswick W4
Fixed-fee, MCIAT-chartered planning drawings for Chiswick (W4) homeowners — London Borough of Hounslow validation and local constraints handled from the start.
Chiswick (W4) sits in Hounslow, and its housing is mostly late-Victorian and Edwardian terraces and semis on the grid between Chiswick High Road and the Thames. These are houses with real rear-garden depth, which is why side-return and wraparound extensions are the recurring project here rather than the basement digs common further into central London.
The designation picture is unusual for a suburban-feeling district. Hounslow operates a borough-wide Article 4 direction removing the right to convert a house to a small HMO, so an HMO scheme anywhere in W4 needs a full application — the direction is not tied to any conservation area. A second direction removes permitted development rights for changes of use creating new dwellings under Class MA/ZA. On top of that, the Chiswick House and Turnham Green conservation areas protect the historic parkland setting and the Victorian frontages respectively. We establish which of those apply to an address before drawing to Hounslow's guidance.
Planning in Chiswick (W4): what to know before you apply
W4 falls under Hounslow's borough-wide Article 4 direction removing the right to convert a dwellinghouse (C3) to a small HMO (C4), so HMO conversions need a full planning application regardless of where in the district they sit. A further direction removes permitted development rights for changes of use that would result in new dwellings (Class MA/ZA). Two conservation areas apply — Chiswick House, protecting the historic parkland setting, and Turnham Green, protecting the Victorian street frontages. The district's deep rear gardens make side-return and wraparound extensions the common project type.
Typical Chiswick housing stock

Planning Drawings for Chiswick (W4) homes: the package and the process
Every planning drawings we prepare for an Chiswick property is drawn to London Borough of Hounslow’s validation standards and tuned to the W4 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
Planning drawings are the scale drawings a London council uses to judge your application: existing and proposed floor plans, elevations, sections and site plans that show the design, scale and neighbour impact of your project. DrawingsDirect produces complete, validation-ready planning drawing sets for extensions, lofts and conversions across London.
What is included in a planning drawing set?
A council will only validate an application that contains the right drawings at the right scale. Our standard planning set covers everything a London validation team expects.
- Site location plan (1:1250) and block plan (1:500)
- Existing floor plans, elevations and sections
- Proposed floor plans, elevations and sections
- Roof plans where relevant, with heights and materials annotated
- A design and access or heritage statement where the borough requires one
How are planning drawings different from building regulations drawings?
Planning drawings show what the building will look like and how it sits in its context. Building regulations drawings show how it will be built safely — structure, insulation, fire escape and drainage. Most projects need both; our Complete package covers the two together with structural calculations coordinated in-house.
| Drawing | Typical scale | What it shows |
|---|---|---|
| Site location plan | 1:1250 | The property in its street context, site edged red |
| Block plan | 1:500 | The building's footprint and position in the plot |
| Floor plans (existing & proposed) | 1:100 / 1:50 | Room layout, walls, openings and the proposed changes |
| Elevations (existing & proposed) | 1:100 / 1:50 | Each face of the building and how it changes |
| Sections | 1:100 / 1:50 | A cut through showing heights, levels and roof form |
