Planning Drawings in Hillingdon
Fixed-fee, MCIAT-chartered planning drawings for Hillingdon homeowners — London Borough of Hillingdon validation and local constraints handled from the start.
Hillingdon is Metro-land in built form: rows of interwar semi-detached and detached houses across Ruislip, Eastcote and Ickenham that lend themselves to hip-to-gable and dormer loft conversions and rear extensions, set against the historic timber-framed core of Ruislip Village and the Colne Valley green belt to the west. These abundant Metro-land semis often retain fuller permitted development rights than inner-London terraces, so a loft or single-storey rear frequently qualifies within the volume limits, though the right route always depends on the plot and its designation.
Unlike much of London, the London Borough of Hillingdon has no borough-wide Article 4 direction affecting typical householder permitted development. The binding constraints are different: Colne Valley green-belt policy toward the western edge and Harefield restricts scale, assessing extensions against strict limits on disproportionate additions to the original dwelling. Conservation control applies in Ruislip Village, Uxbridge (Windsor Street), Northwood, Ickenham Village, Harefield and Eastcote, where permitted development is removed. Toward the south of the borough near Heathrow, aircraft-noise considerations can influence habitable-room and glazing design and need evidencing within the application.
We prepare Hillingdon planning drawings that respect the established Metro-land building line the council expects, checking permitted development eligibility for semi-detached and detached homes first and flagging any conservation, green-belt or aircraft-noise constraint for your address. You get a fixed fee agreed up front, the same council-accepted drawings an architect would produce for usually around 30% less, a roughly seven-day drawing turnaround and free redraws until Hillingdon approves. Most householder applications are determined within the statutory eight weeks once validated, so we work to the council's validation checklist to head off the queries that cause delay.

Planning Drawings for Hillingdon homes: the package and the process
Every planning drawings we prepare for a Hillingdon property is drawn to London Borough of Hillingdon’s validation standards and tuned to the local 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 |
