In Northolt (UB5) we prepare planning and building-control drawings for rear extensions, loft conversions and garage conversions on the district's 1930s semis and interwar homes.

Around the Northolt Village Green conservation area we check the boundary and the setting of nearby heritage buildings first, then advise whether your extension runs as permitted development or needs a full application.

Planning in Northolt (UB5): what to know before you apply

The bulk of 1930s UB5 housing sits outside the small Village Green conservation area and keeps full permitted-development rights for rear extensions and lofts. Plots near the green face conservation-area control on demolition, side extensions and anything affecting the historic setting.

Typical Northolt housing stock

Northolt centres on the historic Village Green around St Mary's Church and Court Farm Road, but the wider UB5 district is predominantly 1930s semi-detached and interwar suburban housing with good-sized rear gardens.

Building Regulations Drawings for Northolt (UB5) homes: the package and the process

Every building regulations drawings we prepare for an Northolt property is drawn to London Borough of Ealing’s validation standards and tuned to the UB5 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 Northolt UB5 — 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 rear extension in Ealing?+
Many Ealing semis and terraces keep permitted development rights for a single-storey rear extension, so a full application isn't always needed. But the borough-wide Article 4 direction on HMO conversions, and conservation areas such as Bedford Park and Pitshanger, remove or restrict those rights in places. We check your address against the designations first and, where it qualifies, confirm permitted development with a Lawful Development Certificate.
What extra control applies in Bedford Park?+
Bedford Park is one of West London's most tightly controlled conservation areas, with detailed control over materials, rooflines, windows and front elevations. A standard permitted-development dormer or cladding change usually won't apply; instead we design to the area's Arts-and-Crafts character and prepare a full householder application with the elevations and materials the council expects — the reliable route to approval there.
How long does Ealing Council take to decide a householder application?+
Ealing determines most householder applications within the statutory eight-week period once they are validated. The commonest cause of delay is a validation query over missing or inconsistent drawings, so we prepare Ealing submissions to the council's validation checklist — correctly scaled existing and proposed plans, elevations and a location plan — to avoid that back-and-forth.
Can you help with a loft conversion on a 1930s Ealing semi?+
Yes. Ealing's Metro-land semis in Perivale, Greenford and Northolt suit hip-to-gable and dormer loft conversions, which frequently qualify as permitted development on semi-detached homes within the volume limits. We confirm eligibility against those limits and any Article 4 or conservation constraint, then produce the planning and building-regulations drawings.
How much do planning drawings cost in Ealing?+
We work to a fixed fee agreed before we start, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Ealing grants approval. The exact figure depends on the project — a single-storey rear extension differs from a double-storey or a loft — so we quote once we understand your scheme rather than on an open-ended hourly basis.
