From the Wikipedia page 
The Thames Barrier Park is a 34.6 acres (14.0 ha) park in London's docklands, named after its location on the north side of the River Thames next to the Thames Barrier. It is intended to aid the regeneration of the area by creating an attractive public space alongside residential and commercial developments. It is adjacent to Pontoon Dock DLR station in the Silvertown area of the London Borough of Newham.
Alain Provost of Groupe Signes won the international competition to design the park in 1995. As the first largely post-modern design in London, the park has a fresh modern look with adventurous planting and dancing water fountains.
