Timber Sash Windows Notting Hill
Heritage and conservation specialists serving Ladbroke, Colville, Pembridge and all Notting Hill conservation areas
Notting Hill sits within the Royal Borough of Kensington and Chelsea, with multiple overlapping conservation areas covering the Victorian terraced streets between Notting Hill Gate and Ladbroke Grove. The Ladbroke Conservation Area, one of the most extensive in the borough, covers the grand stucco-fronted terraces and communal garden squares developed between the 1840s and 1860s. The Colville Conservation Area to the north covers the Portobello Estate, developed around 1860–1875. Both areas have Article 4 Directions in place, meaning window replacements on many properties require planning permission.
The Victorian stock in Notting Hill is characterised by wide six-over-six and four-over-four sash windows, typically with solid horns, slender meeting rails, and either solid or applied glazing bars depending on the period and sub-area. Our Heritage profile replicates these details exactly, solid framed bars where required, putty-fronted glazing, and cords, weights and pulleys, with planning documentation supplied for LBC and conservation area applications.

Why Notting Hill requires a specialist
Article 4 Directions in the Ladbroke and Colville areas remove permitted development rights for window replacements across a significant proportion of the housing stock. This means that even on unlisted terraced houses, replacing sash windows in materials or profiles that differ from the original requires planning permission. RBKC heritage officers in these areas typically expect solid framed glazing bars on properties where the original windows had them.
We carry out a planning assessment at survey stage, identifying whether your property is subject to Article 4 and advising on the specification likely to achieve consent. We prepare LBC drawings and conservation area planning statements where required.
Sash window questions from Notting Hill homeowners
Do I need permission for sash windows in Notting Hill?
In most cases yes. Notting Hill sits almost entirely within Royal Borough of Kensington & Chelsea conservation areas, many covered by Article 4 Directions, so planning permission is required for window replacement. Listed buildings need Listed Building Consent as well. We check your address and prepare the drawings and heritage statement RBKC expects.
Can the colour of the frames stay as it is?
Yes, and on the painted terraces of Portobello, Ladbroke Grove and Elgin Crescent the borough often expects the existing colour to be retained. We finish in any RAL or heritage colour, factory-applied for a longer maintenance interval than site painting.
What glazing suits the tall first-floor sashes?
The full-height first-floor windows typical of Notting Hill's stucco terraces take slimlight units of about 12–16mm without changing sightlines, with vacuum glazing at 8.3mm where the original rebate cannot be deepened. Both keep the slender bar sections the elevation depends on.
Will new windows reduce noise from Portobello Road?
Noticeably. Sealed sashes with acoustic laminated glazing cut street noise substantially, and we quote the acoustic figure for the specification rather than a general claim. Traffic and market noise is the most common reason Notting Hill clients call us.
Do you work on communal stairwell and rear windows too?
Yes. Where a building is in shared ownership we can quote the whole elevation, including stairwell and rear windows, and supply one drawing set for the freeholder, managing agent and council.
