The Srawasthi Mandiraya is the primary office complex of the Western Provincial Council, located in Cinnamon Gardens, a suburb of Colombo.

Built in 1913, it saw use for most of its lifetime as a hostel for Members of Parliament from outside Colombo who were attending Parliamentary sittings.

It is located along Sir Marcus Fernando Mawatha (formerly Edinburgh Crescent).

One of the largest houses in Colombo at the time, Dr de Silva hosted many dignitaries such as Jawaharlal Nehru, Rabindranath Tagore and Lord Donoughmore.
