The Richard Rogers Partnership scheme aims to symbolise democracy by encouraging public participation in the democratic process. The practice said its proposal was the antithesis of the existing and proposed buildings surrounding the site. The scheme comprises a public surface 'firmly anchored to the water's edge', stepping upwards and into the site, enclosing the adminstrative functions beneath it. A lightweight, gently undulating roof stretches out and above to shelter spaces inside and out. The roof of steel and a plinth of slate echo dominant site features.
