The Perdana Putra Building is located in Precinct 1 and overlooks Putrajaya Lake, Putra Mosque and Dataran Putra. This six-storey natural stone clad office complex comprises the Prime Minister's Office, the offices of the Deputy Prime Minister and Chief Secretary to the Government.

The two lower levels of the building sit on a strong perimeter base which supports fluted columns rising across the remaining four levels. The base symbolises the strong and stable foundation that is necessary to administer a dynamic and prosperous country such as Malaysia while the series of columns denote the orderly and united people that support the sovereignty of Malaysia.

The design of the Perdana Putra Building incorporates elements of Islamic-Mogul architecture. Its green pitched roof converges at the onion-shaped glazed mosaic main dome - a replica of Masjid Zahir in Alor Setar, Kedah - and surrounded by four smaller domes denoting iron bunga raya motifs and waterjet stone carvings decorate the Main Block.

The Perdana Putra Building is open to the Public from Mondays to Fridays: 8.00 am - 12.30 pm, 2.00 pm - 4.30 pm and on Saturdays from 8.00 am - 12.30 pm. Closed to the public on Sundays, public holidays and every 1st and 3rd Saturday of the month.
