Stoneworks Prikaz (Russian: Каменный приказ) was an administrative office in Moscow (Russia), which supervised the implementation of the so-called "General Plan of Moscow" (city development plan, elaborated in 1774-1775).
The commander-in-chief (governor-general) of Moscow was in charge of the Stoneworks Prikaz, architect P. Kozhin being its only director during its existence.
All state-owned and private brick and roof tile factories and stonemasons were transferred under the authority of the Stoneworks Prikaz.
Architect Kozhin drew up a plan of rebuilding and rezoning of Moscow, which would define the ways of the city's development in the late 18th - first half of the 19th century.
In 1782, the Stoneworks Prikaz was abolished, its functions being transferred to the Board of Provision of Urban Amenities (Управа благочиния, or Uprava blagochiniya).
