Northern Ireland office fit-out firm 1080 has finished the biggest project of its kind in the past 15 years.
The company has completed work on the new 140,000 sq ft home of US-owned IT company Allstate at Mays Meadow in Belfast.
The business, which is part of The Alpha Group, said the job was the most complex in its history, requiring the delivery of 38 shipments of furniture over four months.
The office lay-out is made up of six floors including height-adjustable desks, sociable workspaces, focus zones, break-out areas, lab spaces, enclave booths, flexible training spaces, kitchen areas and an on-site cafe.
It worked with consultants WDR & RT Taggart, contractors O'Hare & McGovern and Universal Business Installations to co-ordinate the project.
Chris Ingle-Finch, 1080 sales director, said: "Mays Meadow represents one of the most forward-thinking and employee-centric design schemes that we've ever worked on.
"A number of areas were specifically designed to facilitate greater staff collaboration and informal meetings in open spaces, fitted out with high-quality furniture that quite simply helps employees feel at ease and comfortable in their working environment.
"There truly is no other workspace like this anywhere else in Northern Ireland.
"Allstate is a great business asset for the Northern Ireland economy and we are delighted to have been such an integral part of the project."
John Healy, managing director of Allstate Northern Ireland, said: "1080 took time to understand our requirements and delivered to the highest standard.
"The impressive design fits the requirements of our world-class organisation, supporting our employees in defining, delivering and maintaining technology now and for the future."
