Planning Permission in Hillingdon UB10
Fixed-fee, MCIAT-chartered planning permission for Hillingdon (UB10) homeowners — London Borough of Hillingdon validation and local constraints handled from the start.
UB10 spans two distinct worlds: the historic village cores of Ickenham and Hillingdon Village, and the large belt of 1930s suburban semis and detached houses around them where most rear and loft projects happen. On the suburban stock the design conversation is about matching established roofline and frontage patterns, which Hillingdon's guidance sets out clearly.
Inside either village conservation area the emphasis shifts to protecting period character around St Giles and St John the Baptist churches, so materials, rooflines and boundary treatments face tighter control. Because the two conservation-area boundaries are compact, we confirm exactly where a UB10 property falls before choosing a permitted-development or full-application route.
Planning in Hillingdon (UB10): what to know before you apply
Most UB10 householder work sits on interwar suburban housing outside the conservation areas, where Hillingdon has well-established expectations for rear depth, side returns and dormers. The Ickenham Village and Hillingdon Village conservation areas are the exceptions — there, heritage-led design and usually a full application are the right approach.
Typical Hillingdon housing stock
Two protected village centres — Ickenham around St Giles Church and Hillingdon Village around St John the Baptist — of period cottages and Victorian houses, ringed by the substantial 1930s semi-detached and detached suburban stock that makes up most of the wider UB10 postcode.

Planning Permission for Hillingdon (UB10) homes: the package and the process
Every planning permission we prepare for an Hillingdon property is drawn to London Borough of Hillingdon’s validation standards and tuned to the UB10 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
Securing planning permission in London means navigating borough-specific design guidance, conservation areas, Article 4 directions and a validation checklist that differs from one council to the next. DrawingsDirect prepares the existing and proposed drawings your local planning authority needs, submits them through the Planning Portal, and manages the application to a decision — for a fixed fee agreed before we start.
Because we are MCIAT-chartered architectural technologists rather than a general architecture practice, you get the same council-accepted drawings and professional accountability at a typically lower fee, with structural coordination handled in-house.
Do I need planning permission for an extension in London?
Many single-storey rear extensions, loft conversions and outbuildings fall under permitted development rights and do not need a full planning application — but London's dense housing stock, conservation areas and Article 4 directions frequently withdraw those rights. Before you pay for a full application, we check your property against the current permitted development thresholds and your borough's local constraints.
Where permitted development applies, we recommend a Lawful Development Certificate instead of full planning — it is faster, cheaper and gives you a legal document confirming the work was lawful. Where a full application is genuinely required, we prepare it properly the first time.
Permitted development vs a full planning application
Permitted development lets you build within defined volumetric limits without committee review. A full householder application is assessed against the borough's local plan for scale, daylight, neighbour impact and design. We advise which route your project qualifies for and why.
Article 4 directions and conservation areas
If your home sits in a conservation area or under an Article 4 direction, permitted development rights are often removed — meaning even modest changes need consent. Each borough page lists the local directions and conservation areas we routinely design around.
How do you apply for planning permission through the London Planning Portal?
We manage the full lifecycle of your submission — survey, drawings, supporting documents and officer liaison — so you never have to decode a validation checklist yourself.
Phase 1 — existing and proposed site surveys
A laser-measured survey captures your property exactly, so existing and proposed drawings match reality millimetre for millimetre.
Phase 2 — technical drawing package
Site location plan, block plan, floor plans, elevations and sections drawn to your borough's scale and formatting requirements, with a design and access statement where needed.
Phase 3 — liaison with the planning officer
We answer the council's queries, negotiate amendments, and redraw free until the decision lands.
