A layout plan of Sun Yat Sen Villa or Wan Qing Yuan (晚晴园), a double-storey mansion at the corner of Tai Gin Road and Ah Hood Road showing the entrance porch, exhibition gallery, verandah, bronze statue of Sun Yat Sen, and the front garden. The mansion was constructed around 1880s by Mr. Boey Chuan Poh, a Cantonese businessman and proprietor of The Union Times Press, for his mistress, Bin Chan. In 1905, Mr. Teo Eng Hock (张永福), a wealthy Teochew rubber magnate, acquired the mansion for his mother, Madam Tan Poh Neo (陈宝娘). It was renamed "Wan Qing Yuan" (晚晴园). Later, he offered the mansion to Dr. Sun Yat Sen (孙中山) for his revolutionary activities in Singapore and Southeast Asia. It was converted into a museum by Singapore Chinese Chamber of Commerce in 1965 and gazetted by Preservation of Monuments Board as a national monument on 28 October 1994. In November 1997, the mansion was closed for renovations and reopened as "Sun Yat Sen Nanyang Memorial Hall" on 12 November 2001 to mark the 135th birth anniversary of Dr. Sun. In 2009, it was taken over by National Heritage Board. It was closed for major renovations on 11 October 2010 and reopened on 8 October 2011 to mark the 100th anniversary of the 1911 Chinese Revolution.
