The Square with its Gardens is within Islington Council’s designated New River Conservation Area, an area of special architectural and historic interest, the character or appearance of which it is desirable to preserve or enhance. Conservation areas are identified and designated by the Council.
The Square is protected in terms of the provisions of The London Squares Preservation Act 1931 and is included in the London Parks and Gardens Inventory of Historic Green Spaces.
The New River Conservation Area is one of the largest in Islington, and is of outstanding importance. The area includes the site of the New River Head, with its historic industrial and water buildings and Sadler’s Wells Theatre, while the rest of the area mainly comprises late 18th and early 19th century residential estates built by the New River Company, the Brewer’s Company and the Lloyd Baker Estate. These include some of the finest terraces and squares in the Borough. The area has a rare quality and consistency of scale, materials, design and detailing which require careful and sensitive policies for its protection and enhancement.
