The £350 million development is being developed by Qmile Group and is designed by globally renowned architect Foster + Partners.

The four-acre site will comprise five buildings, three of which will be offices and the other two hotels. It is estimated that the office space alone will accommodate up to 4,500 workers.

Iain McAlpine, Indeglås commercial director, said: “We are delighted to be part of another landmark development for Sir Robert McAlpine and look forward to getting works underway on site. Haymarket Square promises to be an exciting project for Indeglås as we build another beautifully designed atrium space.”
