What it is

An official Song manual that standardised timber construction through a module (cai) proportional to the building's size, with dougong brackets, technical drawings and tables of materials and labour. It is the first complete, printed, modular building code.

Printed in 1103 (a 1145 edition survives in copies).

What it led to

  • standardised construction and cost estimates
  • prefabrication of timber components
  • canon of later Chinese architecture
