The results of the renovation project, completed in January 2012, will be shown on the Visit Brighton stand B610 between 6-8 March.
Brighton Centre created a larger entrance and reception area with a new fully glazed front to the building and a re-designed third floor restaurant, offering panoramic views of the seafront.
Other improvements include 4,000 new seats in Auditorium 1, the refurbishment of Auditorium 2, better equipped and re-decorated meeting facilities and break out rooms throughout the centre alongside new signage, furnishings and fittings.
The 3D virtual tour allows visitors to 'walk through' the venue.
"We are looking forward to showcasing our excellent new facilities to all conference and exhibition organisers attending International Confex this year," says Penny Parker, business and communications manager at The Brighton Centre.
"The refurbishment represents a significant and comprehensive upgrade of our conference, exhibition and meeting spaces. It also capitalises on our fantastic location, bringing us closer to the seafront and providing delegates with inspiring, uninterrupted views of the sea through new floor-to-ceiling windows. The 3D virtual tour brings these improvements to life for visitors and is the next best thing to seeing the Centre in person".
