Timber Sash Windows Chiswick
Heritage and conservation specialists serving all Chiswick conservation areas
Chiswick contains some of West London's most intact Georgian and Victorian streetscapes, particularly around Turnham Green, Bedford Park, Britain's first garden suburb, and the Chiswick Mall riverside. The London Borough of Hounslow has designated multiple conservation areas here, with strict like-for-like requirements for window replacements.
We work across all Chiswick conservation areas including Bedford Park, where the Arts and Crafts character requires particularly sympathetic window profiles. Our Heritage Sash Windows are accepted by Hounslow heritage officers. We supply full LBC drawings and specification documentation as standard.

Why Chiswick requires a specialist
Hounslow's conservation officers apply detailed controls across Chiswick's conservation areas, with particular attention to Bedford Park's Arts and Crafts character and the Georgian frontages along Chiswick Mall. Replacement windows must match original timber sections, glazing bar profiles and ironmongery.
For listed buildings, and Chiswick has many, Listed Building Consent is required for any window replacement. We provide LBC drawings and full specification documentation as standard, and advise on vacuum glazing where the heritage officer requires the slimmest possible unit.
Sash window questions from Chiswick homeowners
Do I need planning permission for sash windows in Chiswick?
It depends on the street. Hounslow has conservation areas covering Bedford Park, Chiswick Homefields, Grove Park and Strand on the Green, and Article 4 Directions apply in parts of them, which removes the right to change windows without permission. Outside those areas a like-for-like timber replacement is often permitted development. We confirm which applies to your address at the free survey.
What is required in Bedford Park?
Bedford Park is one of the most tightly controlled areas in the borough. Hounslow expects the original Arts and Crafts detailing to be reproduced: small-pane upper sashes, correct bar sections, white painted joinery and no change to the opening. We template each window and match the existing pane pattern exactly.
Can you match Victorian sashes with horns and margin lights?
Yes. The late-Victorian terraces around Chiswick Homefields and Grove Park often have horned sashes, sometimes with coloured margin lights. We copy the horn profile and can reinstate coloured or etched margin glass where it survives or is documented.
Will new sash windows help with aircraft and A4 noise?
Yes, and it is the most common reason Chiswick clients call. Sealed sashes with acoustic laminated glazing give a marked reduction in flight path and Great West Road noise. We quote the acoustic rating for your specification so you can compare options properly.
How long does a whole-house Chiswick project take?
For a typical Victorian terrace, allow four to eight weeks for a planning decision where one is needed, eight to ten weeks manufacture, then three to five days on site. Houses outside the conservation areas can usually start manufacture straight away.
