The Grade I listed Leaden Hall was one of the most important houses in the medieval Salisbury Close. Originally built as a canonry by Canon Elias of Dereham (who oversaw the construction of the cathedral), the original building was one of the earliest on The Close and partly intended to be a model for other canonical houses. In 1720, the house was largely demolished and rebuilt by Canon Edward Talbot and extensively remodelled again and extended in 1819.

In 1915, the last remaining ruinous part of the original canonry was demolished, with the medieval window and doorway retained and rebuilt in a garden wall. Leaden Hall remained a canonry until it was leased to Leaden Hall Girls' School in 1947. Since 2017, Leaden Hall has laid empty.

DHV Architects are leading the conservation and renovation of Leaden Hall as part of the Salisbury Cathedral master plan to revitalise the building and provide facilities to support the operation and mission of Salisbury Cathedral for the foreseeable future.

A planning application for the project at Leaden Hall has been submitted. The proposal seeks to provide a location for the cathedral organisation staff to unite in one place; provide a visible and welcoming location for visitors to the cathedral offices; revitalise the picturesque, landscaped grounds, including formal gardens, a new orchard, and enhance the biodiversity of the site; and provide sustainable long-term energy sources, resulting in the development achieving Net Zero Carbon from the outset.
