Singapore has a new President. The first female to hold the post and the first Malay for 47 years: http://www.straitstimes.com/politics/staying-put-in-yishun-6-things-to-know-about-president-elect-halimah-yacobs-jumbo-flat
True to form, she will be staying put in her HDB flat, where she has lived for 30 years. This is very much like all previous Presidents, although they have an official residence at the Istana.
The same applies to the Prim Ministers, although there is an official PM residence in the Istana grounds it has been used as a VIP Guest House since independence in 1965.
