The centrepiece takes the form of a rotunda constructed as a brick drum with a conical zinc roof.  A segment has been cut out of the rotunda and is enclosed by full height structural glass for maximum transparency, creating the impression that the surrounding parkland extends into the Atrium itself.  The link between outdoors and inside is further enhanced by a footbridge which spans over the terraces and brings visitors directly to the gallery which encircles the rotunda at first floor level.

The new atrium and banqueting suite, provides meeting rooms and generous public spaces, incorporating dining facilities, bars and ancillary accommodation over two levels, doubling the capacity of the existing centre.

With flexible facilities that can accommodate between 20 and 588 delegates in total, the centre has become the leading conference venue in the East Midlands.
