just saw https://www.nlb.gov.sg/main/article-detail?cmsuuid=9c0a34bc-2b4f-47bf-b878-788d1ded1096 says "Sited atop the hill, the two-storey Tudor-styled bungalow looked out on a 19-hectare park and commanded a sweeping view of Keppel Harbour. The hill was then believed to be the highest point in Singapore on which a bungalow sat."

so maybe just erstwhile highest bungalow, worth a note at most?
