Prime Minister's office
I was told this is the Prime Minsiter Office by some security personal on the ground where I was taking this photo. It probably is as if I am not mistaken; the location of this building is strategically at the highest point in this area compared to the other buildings surrounding it as well as further down in the next precints. It is also next to the biggest mosque in Putrajaya.
The building location is at Precint 1 in Putrajaya.
