Conservation areas
There is no "Brentford Waterside", "Ferry Lane" or "Grosvenor Road" conservation area, and Boston Manor is in Hounslow rather than Ealing. The current list is on Hounslow's Article 4 page.
Housing stock in Brentford
Hounslow's Brentford design code chapter describes The Butts as predominantly Georgian, with "a complete Victorian New Town of terraces arranged around open space" to its east, and Boston Manor as "mostly early two-storey inter-war semis, and short-medium terraces with rear access lanes".

Frequently asked about Brentford
Is there an Article 4 direction on windows in Brentford?
No. Hounslow has only two conservation areas with an Article 4 affecting windows - Bedford Park and Gunnersbury Park - and neither is in Brentford. The borough's other Article 4 directions cover HMO conversion and commercial-to-residential change of use, not householder windows.
So do I need planning permission for replacement windows in TW8?
For an unlisted house, usually not. Hounslow's adopted SPD states that "most houses in the borough do not require planning permission to install new or relocate existing windows and doors". Listed buildings and flats are the exceptions, and inside a conservation area the design still has to be appropriate even where permission is not needed.
Which conservation areas actually cover Brentford?
The Butts, St Pauls Brentford, Kew Bridge and Grand Union Canal & Boston Manor. Names such as "Brentford Waterside" and "Ferry Lane" do not appear on Hounslow's list of conservation areas.
What suits a Georgian house at The Butts?
Fine sightlines and correct glazing bar proportions matter more than the frame material. Where permission is required, Hounslow's SPD says the council will normally refuse replacements whose materials, design, colour, proportion and finish differ from the original prevailing types.
How far is Brentford from your base?
Brentford neighbours Isleworth, so it is one of the closest areas we cover - useful for survey scheduling and for any return visit after installation.
What actually applies in Brentford
Brentford is in the London Borough of Hounslow. Four conservation areas cover TW8, and none of them carries an Article 4 direction removing permitted development rights for windows or doors.
That makes Brentford unusually straightforward compared with Chiswick a few miles east. The adopted policy is Policy CC4, Heritage, in the Hounslow Local Plan of September 2015, which requires development in a conservation area to "conserve and take opportunities to enhance the character of the area, and respect the grain, scale, form, proportions and materials of the surrounding area".
The design detail sits in the Character, Sustainability and Design Codes SPD (2024), which superseded the 2017 Residential Extensions Guidelines. Its window section asks for retention and repair first, and notes that double or triple glazed windows are often available in traditional materials and styles.
