Krrish Square, Mixed-use skyscraper in Fort District, Colombo, Sri Lanka.

Krrish Square, also known as The One, is a tri-tower development on 4.3 acres in Colombo Fort. The tallest tower, The One Residences, is planned for 92 floors and 376 m; the 80-floor Ritz-Carlton Residences and the 77-floor JW Marriott hotel stand beside it. The towers rise from a shared glass podium with a light panel bearing a large abstract logo, and a low red-tiled roof with arched windows sits at street level.

The One was launched as a US$650 million tri-tower project on 4.3 acres of Colombo Fort, estimated as the 10th largest of its kind in the world. The 80-floor Ritz-Carlton Residences tower had reached 33 floors by August 2019 and was scheduled for completion in December 2021. The 77-floor JW Marriott hotel was set for December 2023, and the 92-floor One Residences tower, planned to reach 376 m, for 2027. The scheme also includes refurbishing the 200-year-old Transworks Square as a designer-brand mall.

The complex absorbs Transworks Square, a 200-year-old heritage site in Colombo Fort that is being refurbished as a mall for designer brands. The three towers carry the Ritz-Carlton Residences, Sri Lanka's first JW Marriott hotel and The One Residences, names tied to Marriott International's brands.

The site covers 4.3 acres (1.7 ha) of Colombo Fort, about two minutes from the World Trade Centre towers and five minutes from the Galle Face Green esplanade. The three towers are being finished in stages: the 80-floor Ritz-Carlton Residences first, the 77-floor JW Marriott hotel later, and the 92-floor One Residences tower last. Expect construction activity around the shared podium and Transworks Square.
