Southern Railway headquarters administrative building, Chennai, is an Indo-Saracenic structure located adjacent to the Chennai Central on Poonamallee High Road.

The building was built at a cost of ₹ 3 million by H. H. Wadia and Bros, a leading Porbandar-based contractor.

[1][2] Built for the first time in India in reinforced concrete in classical and Dravidian styles, the building was designed by N. Grayson, a 'company architect', working for the Madras & Southern Mahratta Railway.

The central bay has two rectangular wings, both of which are arranged around a lush courtyard.

The structure was built with large windows to allow the sea breeze to waft through, reaching the courtyard from the front and then going out through the opposite wing.
