The Unique Challenge of W11 Properties
Notting Hill's famous stucco-fronted terraces — many dating from the 1840s–1860s — feature some of London's tallest sash windows, often exceeding 2.4 metres in height. The Ladbroke Conservation Area imposes strict controls on external alterations, making secondary glazing the only viable upgrade path. Our bespoke vertical sliding units are engineered specifically for these oversized openings, with counterbalanced mechanisms that ensure effortless operation despite the panel weight.
Holland Park's detached and semi-detached villas present different considerations: deep bay windows, curved glass features, and elaborate cornicing that requires careful frame routing. We use a combination of hinged and lift-out panels to navigate these architectural complexities, maintaining full access to original shutters and window furniture.
The iconic Victorian and Edwardian terraces of Notting Hill and Holland Park often suffer from thermal heat loss through large sash windows. Our guide for W11 and W14 focuses on thermal performance and draught proofing. Because these properties often feature unique architectural details, we highlight 'custom-color' matching where secondary frames are powder-coated to match the exact RAL color of your existing interior woodwork, ensuring a seamless luxury finish.

Preserving Period Windows in Notting Hill & Holland Park
Notting Hill's iconic pastel-painted terraces along Lansdowne Crescent and Elgin Crescent, together with Holland Park's grand Italianate villas on Addison Road, represent some of West London's most photographed streetscapes. The windows in these properties — typically tall Victorian sashes with delicate glazing bars — are fundamental to the area's visual identity. Many sit within the Ladbroke Conservation Area, where external alterations are strictly controlled. Secondary glazing provides the ideal solution: a fully internal, reversible upgrade that delivers up to 80% noise reduction from the bustling Portobello Road and Westbourne Grove, while preserving every original detail that makes W11 so distinctive.
Listed Buildings & Conservation
Do I need Listed Building Consent for secondary glazing?
Generally, secondary glazing is considered a reversible internal alteration and is widely supported by Historic England. However, in Grade I properties or sensitive areas like St James's, it is always best to check with the local conservation officer. Our guides help you choose 'Invisible' frames that are most likely to be approved.
