A connected environment for businesses, people, and ideas to grow.
Orion City brings together commercial workspaces, dependable infrastructure, and everyday conveniences to help businesses establish, operate, and expand in Sri Lanka.
Developed to serve the needs of the IT and Business Process Management industry, Orion City has grown into a business community accommodating local enterprises and international organisations. From shared offices to customised corporate spaces, our approach gives businesses the flexibility to find the right environment for their operations.
At our Colombo 09 campus, workplace infrastructure is supported by power backup, connectivity, on-site data centre facilities, security, and dedicated facilities management. Dining, banking, fitness, childcare, and hotel facilities bring added convenience to the working day.
Through OC by Orion City in Colombo 03 and planned developments including Orion Tower II and Orion City Kandy, we continue to create opportunities for businesses to grow with us.

Orion City seeks to nurture and uplift not only these business owners, but also the whole IT industry in Sri Lanka.
Orion City follows the concept of the self-contained city, offering its tenants the possibility of growing their businesses by providing the best workspaces possible to the brightest and the best in the IT/BPM industry, along with modern conveniences
Vision & Positioning
Our Vision
To create end-to-end IT infrastructure and self-contained, future-ready workspaces where IT and BPO companies thrive in proximity to reduce costs, strengthen innovation, and nurture Sri Lanka’s IT and BPM industry.
Our Mission
To create sustainable, self-contained, and future-ready workspaces that nurture and uplift startups, enterprises, and the broader Information Technology and Business Process Management (IT/BPM) industry in Sri Lanka.
The Orion Brand
Named after the constellation, Orion City draws inspiration from a symbol of aspiration and possibility. The three stars of Orion’s Belt—Alnitak, Alnilam, and Mintaka—inspired the architectural concept behind Orion Towers.
That inspiration carries into our purpose: creating spaces where businesses can pursue their ambitions, expand their capabilities, and reach further.
