Arnold Circus is a unique garden and heritage asset in the 1890s Boundary Street Estate in east London. Having been designed as the centrepiece of Britain’s first publicly-funded social housing scheme, intended to improve public health, promote exercise and provide a ‘stage’ for the local community, it declined over the years. Today the Circus is beautiful again. The Friends of Arnold Circus have restored and maintained this asset in partnership with Tower Hamlets. It underwent a major regeneration in 2010, led by LDA Design. Careful research and meticulous work has ensured a balance between restoration and sustainability. This has resulted in colourful planting, improved biodiversity, a bandstand with handmade roofing tiles, historic railings, new seating and a rainwater-harvesting system with underground storage.
