When it was built in 1905 as a residence for government officers, this whitewashed mansion was a typical example of Hong Kong colonial architecture. The pitched tile roof is a nod to Chinese building styles, while large verandahs allowed its inhabitants to stay cool in the summer. There’s also a watchtower that overlooks Tolo Harbour. Today, the villa is protected as a historic monument and it is home to the WWF’s Island House Conservation Studies Centre, with exhibitions, workshops and an English-style garden — home to 140 species of plants. Bookings are required for public tours (Cantonese only) of Island House and its gardens.
