The commission to design the main focal point pavilion for West Street was won by Chrysalis Arts with a design by Kate Maddison submitted for the International Competition of the Henry Cort Millennium Exhibition.

The proposal celebrated Fareham as a Market Town and incorporated contemporary art/ironwork using 17th Century fabrication techniques to celebrate Henry Cort, the inventor of the first industrialised process of producing wrought iron. The artist produced a design that would utilise timber, steel, iron, cast iron and tensile fabric and included images of Fareham Market both contemporary and historic. She collaborated with a structural engineer to detail the design and Chrysalis Arts managed the implementation process with a team of skilled blacksmiths, metal casters and contractors.

The Perfomance Pavilion is located at the pedestrianised centre of West Street at the entrance to Millennium Square. It is a 9-metre diameter circular structure with a series of six paired timber columns that support 12 iron panels and a tensile fabric roof. The upper iron panels depict an image of a cattle head taken from an archive photo of Fareham's cattle market, the head and horns inspired the elegantly curved shape formed at the top of the panels as they taper to the cast iron finials. The lower panels depict images of market trading and were developed from photos taken by the artist of Fareham market.

The louvred iron panels are a feature of the artist's work at the time, where an image is cast onto a panel made up of a series of flat bars. The bars are twisted to an angle so that as the viewer walks around the work, the image changes. When seen from the front the image is solid and the surround is void, but as the viewer moves to the side the image breaks up and becomes void and the surround changes to solid.

The contemporary design for the roof includes a laminated ring beam with a timber and steel structure enclosed within a tensile roof membrane supported from a single adjustable support. The structure design draws reference to historic sailing ships with their cloth sails and tall timber masts.

The cast iron feet, finials, guttering and down pipes were made especially for this Pavilion and display an exceptional craftsmanship to complement the quality of rest of the commission.

The permanent iron work exhibition including the Performance Pavilion was opened by the Mayor of Fareham and the Lord Lieutenant of Hampshire in April 2000 and can be viewed in West Street, Fareham.
