Plumstead Library officially opened in 1904 and is one of the earliest of the many funded by the philanthropist Carnegie. The project involved the restoration of the original library, and a 1930 extension, excluded from the listing, was demolished to allow for an extension to accommodate new leisure facilities. The result is a carefully detailed building of high-quality materials and a simple appearance that does not compete with the restored listed library. The project won a RIBA London award and a RIBA London conservation award in 2022.
