A former library and urban district council building will be preserved after it was granted Grade II listed status.
The Hampton Wick Association and architect Richard Pain campaigned to protect the building in Hampton Wick High Street and lobbied English Heritage for listed status.
The building dates to 1884 and has an art nouveau terracotta front with a Flemish gable, columns, stained glass panels and the medallion of Hampton Wick, the stag and crown.
The group welcomed the news, which means the historical icon’s facade and interior will be saved for future generations.
Councillor Tony Arbour said: “This decision is a great triumph for the Hampton Wick Association and local people.
“The building represents the proud independence of the Wick and the Grade II listing is a tribute to them.
“We shall continue to preserve our distinct riverside community.”
English Heritage agreed to upgrade the building’s status from townscape merit due to architectural interest, historic interest, its rarity and described the civic landmark as charming and well detailed.
