Thalawathugoda is a suburb of Colombo city. It is located approximately sixteen (16) kilometres from the city centre of Colombo, adjacent to Battaramulla and Pelawatte on the Borella-Kottawa main road, bordering Sri Jayawardenapura-Kotte (The administrative Capital of Sri Lanka). The Diyawanna Oya (Parliament Lake) forms the "Sri Jayawardenapura-Kotte" side boundary of Thalawathugoda. The beautiful natural landscape consisting of paddy fields and marshlands in this area attracts many nature lovers. This is a rapidly developing residential area with many facilities. New modern luxury housing schemes are being developed around Kalalgoda Road and Hokandara Road to cater to high end housing demand. A notable expatriate and upper middle class local population resides in Thalawathugoda.
Earlier Thalawathugoda had a sub post office which is controled by the Battaramulla main post office. Promoted Thalawathugoda Post Office was opened recently. However, a few areas fall under Hokandara and Pannipitiya postal limits.
