Worthing Museum and Art Gallery, an Edwardian Baroque Grade II listed building, is set to install secondary glazing throughout the property after approval from Adur and Worthing councils.
The decision, made on January 24, 2025, will see the museum improve its thermal efficiency while maintaining the original timber single-glazed windows.
The listed building consent was sought by the museum, which is located on Chapel Road, within the Chapel Road conservation area.
The museum, originally opened in 1908, is set to receive the internal glazing, which will be set back from the main windows to ensure minimal visual impact.
The original timber windows will remain unchanged, keeping the building’s external appearance intact.
The improved thermal efficiency is expected to contribute to the building’s sustainability, alongside the preservation of its historic character.
The Worthing Society also supported the proposal, considering secondary glazing the most suitable method for listed buildings as it does not harm the external character.
The museum is surrounded by other civic buildings, including the Grade II-listed Town Hall, which had secondary glazing installed in 2021.
The public benefit of the works, in terms of improved thermal and noise insulation, was considered to outweigh any harm, as it will enhance the visitor experience and reduce operational costs.
The proposal aligns with Historic England Advice Note 18, which states that secondary glazing typically causes minimal harm to historic fabric and architectural interest.
The works are expected to be carried out without scaffolding or road closures, with minimal disruption to neighbouring properties.
