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.

Building Regulations Drawings for Hillingdon (UB10) homes: the package and the process

Every building regulations drawings 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.

Where planning drawings gain design consent, building regulations drawings prove your project meets the technical standards for a safe, warm, structurally sound building. DrawingsDirect produces full-plans building control packages for London extensions, lofts and conversions, with structural calculations produced in-house rather than subcontracted.

What do building regulations drawings cover?

A building control package translates the approved design into a buildable, compliant specification.

  • Construction sections and detailed junctions
  • Structural drawings and calculations (steel beams, foundations, loadings)
  • Part L thermal performance and insulation specification
  • Fire safety — escape routes, protected structure, alarms
  • Drainage and ventilation layouts

Full Plans or Building Notice — which should I choose?

A Full Plans application has your drawings checked and approved by Building Control before work starts, giving certainty and a document lenders and buyers like to see. A Building Notice lets simpler work start sooner but is inspected as it proceeds, with less up-front certainty. For most London extensions and loft conversions we recommend Full Plans, and prepare the package accordingly.

FAQ

Building Regulations Drawings in Hillingdon UB10 — FAQs

Do I need building regulations approval as well as planning permission?+
Almost always, yes. Planning permission covers what the building looks like; building regulations cover how safely it is built. Most extensions and loft conversions need both.
How long does Building Control approval take?+
A Full Plans application is typically assessed within about five weeks. We prepare a complete package and respond to any conditions promptly, so approval is not held up by missing detail.
Can building regulations drawings be done after planning approval?+
Yes. Many homeowners secure planning permission first, then commission the building regulations package before starting on site. We can pick a project up at either stage.
Are structural calculations included?+
Yes — we produce structural drawings and calculations in-house as part of the building regulations package, so your builder has everything to price and build.
Can you submit to Building Control for me?+
Yes, we prepare and submit the Full Plans package and respond to any Building Control queries.
Do I need planning permission for a loft conversion in Hillingdon?+
Hillingdon's Metro-land semis and detached houses in Ruislip, Eastcote and Ickenham suit hip-to-gable and dormer lofts, which frequently qualify as permitted development within the volume limits. The exceptions are the conservation areas — Ruislip Village, Uxbridge and Northwood — and green-belt land toward the Colne Valley. We check your address and can confirm permitted development with a Lawful Development Certificate.
How does the Colne Valley green belt affect my Hillingdon project?+
On green-belt properties toward the western edge of the borough, extensions are assessed against strict limits on disproportionate additions to the original dwelling. It does not rule out an extension, but scale and siting matter and the case must be evidenced carefully. We confirm whether your property is green belt and design a scheme that stays within policy.
Does proximity to Heathrow affect my plans?+
It can toward the south of the borough, where aircraft-noise considerations may influence habitable-room and glazing design. We evidence these considerations within the application where they apply so the council can validate and approve without repeated revisions.
How long does Hillingdon Council take to decide?+
Hillingdon determines most householder applications within the statutory eight-week period once validated; green-belt and conservation cases can involve additional consultation. We prepare Hillingdon submissions to the council's validation checklist to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Hillingdon?+
We work to a fixed fee agreed upfront, usually around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Hillingdon approves. A dormer loft, a suburban extension and a green-belt case differ in the evidence required, so we confirm the fee once we understand your project rather than billing by the hour.
