TW8 is Brentford, where the Georgian jewel of The Butts sits a short walk from Victorian terraces and the fast-changing waterside quarter, and owners here typically want a rear extension, a side return or a loft conversion that respects an older townscape.

The Butts conservation area holds a dense run of Grade II listed houses, so before assuming permitted development it is worth checking whether your home is inside the boundary or itself listed, because that shifts the route to a full householder application and, for listed homes, separate listed building consent.

Planning in Brentford (TW8): what to know before you apply

Unlisted homes outside The Butts can often extend under permitted development within the usual limits. Inside the conservation area, and for the many listed Georgian houses, a householder application is normal and listed building consent is required for any works to a listed fabric.

Typical Brentford housing stock

The Butts is a tree-lined Georgian square of 18th-century brown-brick townhouses and cottages, many Grade II listed, while the rest of TW8 mixes Victorian terraces, post-war housing and recent waterside apartment schemes along the Brentford riverside.

Planning Drawings for Brentford (TW8) homes: the package and the process

Every planning drawings we prepare for an Brentford property is drawn to London Borough of Hounslow’s validation standards and tuned to the TW8 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 Brentford TW8 — 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.
