Alexandra Palace Heritage Roof Glazing Works
ARRT Group carried out specialist high-level glazing maintenance works at Alexandra Palace, London, supporting the preservation and weatherproofing of the building’s historic glazed roof structure.
The work was completed on a prominent multi-level roof lantern with extensive traditional glazing, metal framing and decorative perimeter panels. Rope-access techniques enabled the team to reach the elevated roof-level sections safely while avoiding unnecessary scaffolding and minimising disruption to the historic building fabric.
