Ark is currently preparing a planning application for a data centre campus on the site of the now vacant Mercure Hotel on Tylers Way, alongside adjoining land to the southeast.
Ark’s goal is to meet the ever-growing demand for data centre capacity in a way that provides real benefits to the people and the community. The state-of-the-art data centre campus will be powered by 100% renewable energy and create highly skilled jobs on-site with as well as further jobs in the area.
The proposed development will be a best-in-class campus able to deploy a full suite of government, Enterprise, Cloud and AI workloads across Ark's diverse customer base which includes many of the most well-known and valuable tech companies in the world.


Ahead of the submission of the final phase, Ark will be consulting residents on the plans. An event will be held at Crane Community Centre at Fuller Way, Hayes, Middlesex, UB3 4LW on 27 November, 15:30-19.30. This will provide a chance for residents to meet the project team and share their views on the proposals.
