Timber Sash Windows Islington
Heritage and conservation specialists serving Barnsbury, Canonbury and all 42 Islington conservation areas
Islington has 42 conservation areas covering approximately 50% of the borough, one of the highest proportions in London. The Georgian squares and terraces of Barnsbury and Canonbury, the early Victorian streets of Highbury, and the historic core of Clerkenwell all sit within designated areas where window replacements are subject to planning scrutiny. In Barnsbury, Canonbury, and St Peter's, Article 4 Directions are in place, removing permitted development rights and requiring planning permission for window replacements that would otherwise be consent-free.
The typical sash window in Islington's conservation areas is a two-over-two or six-over-six box sash in softwood, with a solid horn to the top sash, a 45mm meeting rail, and putty-glazed individual panes in the earlier Georgian and early Victorian stock. Our Heritage Sash Windows replicate this construction exactly, solid framed glazing bars, putty-fronted slimlight double glazing, and documentation for LBC and conservation area applications as standard.

Why Islington requires a specialist
Islington Council's conservation officers apply Article 4 Directions across Barnsbury and Canonbury, the two areas with the densest concentration of Grade II listed Georgian terraces in the borough. On these streets, window replacements require a full planning application with scaled section drawings, glazing specifications and a heritage statement. Applications without adequate documentation are routinely delayed or refused.
Our survey includes a planning assessment at no charge. We identify Article 4 status, advise on the correct profile and glazing specification, and prepare all drawings and documentation required for the planning application.
