Planning Drawings in Feltham TW13

Fixed-fee, MCIAT-chartered planning drawings for Feltham (TW13) homeowners — London Borough of Hounslow validation and local constraints handled from the start.

Feltham is an outer-west Hounslow suburb built largely between the wars and in the post-war decades, so the bulk of our work here is family-driven: single-storey rear extensions, side-return infills and loft conversions on 1930s semis and estate housing. Wide plots on roads such as Southern Avenue and Ashmead Road usually leave comfortable room to extend under permitted development while keeping the front elevation intact.

Where a plot sits near the St Dunstan's or Hanworth Park conservation areas, or on the lower ground close to the River Crane, we design to Hounslow Council's expectations from the outset — matching brick and roof lines, respecting the depth and height limits, and building in flood-resilient drainage detail so the application clears validation without an avoidable refusal.

Feltham (TW13) — planning at a glance

Council: London Borough of Hounslow
Postcode district: TW13
Planning portal: View the Hounslow planning portal
Housing stock: Feltham is dominated by 1930s bay-fronted semis and post-war council-built estates, with generous rear gardens on roads like Southern Avenue and Glebelands Road. Plots are wide enough for single-storey rear extensions, side infills and hip-to-gable loft conversions without needing to touch the front elevation.
Article 4: London Borough of Hounslow does not publish its Article 4 directions to the national planning register, so permitted development rights in Feltham (TW13) can’t be confirmed from open data alone — we check the direction schedule with the council before recommending a route, as part of the fixed fee. No published householder Article 4 across Feltham's interwar and post-war estates — most rear and side extensions sit within permitted development, so the constraint is proximity to the Hanworth Park and St Dunstan's conservation areas rather than a borough-wide direction.

Sample streets: Southern Avenue · Glebelands Road · Ashmead Road · Browells Lane
Local constraints: Most of the housing stock is interwar/post-war semi-detached, so party wall agreements with immediate neighbours are the norm for rear and side worksThe St Dunstan's and Hanworth Park conservation areas tighten what is acceptable near the village core and parkland edgeFeltham Town Centre conservation area governs the busier commercial frontages rather than the residential streetsLow-lying ground near the River Crane and Longford River means some plots fall within Environment Agency flood zones and need a drainage-aware design

Planning in Feltham (TW13): what to know before you apply

There is no published householder Article 4 direction in Feltham, so most rear and loft projects proceed under permitted development. Watch the St Dunstan's, Hanworth Park and Feltham Town Centre conservation areas, and the flood constraint on plots near the River Crane, where PD rights and extension depths are more tightly read.

Planning Drawings for Feltham (TW13) homes: the package and the process

Every planning drawings we prepare for an Feltham property is drawn to London Borough of Hounslow’s validation standards and tuned to the TW13 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.

FAQ

Planning Drawings in Feltham TW13 — FAQs

What scale should London planning drawings be?+

Site location plans are 1:1250, block plans 1:500, and floor plans, elevations and sections are typically 1:100 or 1:50. We format every drawing to your specific borough's requirements.

Do I need an architect to produce planning drawings?+

No. MCIAT-chartered architectural technologists produce the same council-accepted planning drawings with the same professional accountability, and councils assess the drawings, not the author's job title.

How many revisions are included in the fee?+

All of them. The fee is fixed and we redraw free until your council approves — revisions requested by a planning officer never cost you extra.

Can you draw from my existing plans?+

We can work from existing measured drawings, but for accuracy we usually carry out a laser survey so the proposed set matches your property exactly.

Do planning drawings guarantee approval?+

No drawing can guarantee a decision, but drawing to the local plan and validation checklist maximises your odds — and we redraw free until approval.

Do I need planning permission for an extension in Hounslow?+

It depends on the area. The interwar semis of Osterley, Hounslow and Feltham often retain permitted development rights for rear extensions and lofts, while the Chiswick terraces and Bedford Park sit within conservation areas where those rights are removed. We check your address against the designations first and can 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.

Does Heathrow or the river affect my Hounslow project?+

They can. Toward the west of the borough, aircraft-noise considerations near Heathrow may influence habitable-room and glazing design, and along the Thames at Strand-on-the-Green and Isleworth the flood zone must be addressed. We evidence these considerations within the application where they apply so the council can validate and approve without repeated revisions.

How long does Hounslow Council take to decide?+

Hounslow determines most householder applications within the statutory eight-week period once validated; Bedford Park, conservation and riverside cases can involve additional consultation. We prepare submissions to the council's validation checklist to avoid the drawing queries that cause most delays.

How much do planning drawings cost in Hounslow?+

We agree a fixed fee before starting, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Hounslow approves. A suburban Osterley extension and a Bedford Park application differ in the evidence required, so we quote once we understand your address and project rather than by the hour.
