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.

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

The full architectural package has to serve three audiences that want different things from the same building. Planning officers want context, massing and materials; Building Control wants construction, insulation and fire strategy; your builder wants dimensions precise enough to price and set out from. One coordinated model behind all three keeps them agreeing with each other.

That coordination is the part clients notice later. When the planning set and the construction set are drawn from separate sources, the discrepancies surface on site — a beam that will not fit the approved roof line, a window head that has moved. We issue numbered, revision-controlled sheets so everyone is building from the same version.

Building form also sets how much design work there is to do. A detached house can usually take an addition on its own terms, while a terrace has to negotiate two party walls, a shared roof line and a neighbour's windows — the same brief, several times the coordination.

What do architectural drawings include?

A complete architectural package carries your project from idea to buildable detail, so builders quote accurately and councils and Building Control approve confidently.

  • Concept and feasibility sketches
  • Planning drawings for the local authority
  • Building regulations drawings with construction detail
  • Structural drawings and calculations
  • Schedules, specifications and material annotations

Architect or architectural technologist — which do I need in London?

For residential planning and building regulations work, an MCIAT-chartered technologist produces the same council-accepted drawings with the same professional accountability as an architect, typically at a lower fee. Councils do not score applications by the author's job title — they score the drawings. The table below compares the two on the factors homeowners actually care about.

What are the stages of an architectural drawing package?

A full architectural package moves through clear stages, each producing drawings you own and can act on. You can stop at any stage — many homeowners take a project to planning approval first, then commission the technical package once they are ready to build.

Concept and feasibility

Sketch options that test what your budget, plot and borough will allow, so you commit to a direction before detailed drawing begins.

Planning drawings

The scaled existing and proposed set your council assesses — floor plans, elevations, sections and site plans formatted to the borough's validation checklist.

Building regulations drawings

The construction-level package: sections, junction details, structural calculations and thermal and fire specification for Building Control.

Construction detail

The final layer of detail and schedules your builder prices and works from on site.

FAQ

Architectural Drawings in Northolt UB5 — FAQs

Are architectural drawings the same as planning drawings?+
Planning drawings are a subset of the architectural package — the drawings used specifically for a planning application. The architectural drawings also include building regulations and construction detail.
Will a technologist's drawings be accepted by my council?+
Yes. MCIAT-chartered technologists are a recognised professional body and their drawings are routinely accepted and approved by every London borough.
Can you take my project all the way to construction?+
Yes — from feasibility through planning, building regulations and structural detail, to a set your builder can price and build from.
Do I own the architectural drawings you produce?+
Yes. The drawings are yours to use, and any competent builder can price and build from them — you are never locked into a single contractor by the drawing package.
Can I commission just the planning stage for now?+
Yes. Many homeowners take a project to planning approval first and add the building regulations and construction package later. We stage the fee to match, so you only pay for the stage you need.
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.
