NATSPEC is the National Master Specification for use with projects of all types and sizes. For each project, you select  the appropriate NATSPEC worksections from the National Classification System and download them using SPECbuilder specification compilation software. NATSPEC worksection Templates are provided as MS Word files which you  edit to suit the project. NATSPEC includes most, but not all, technical requirements for the majority of projects. Additional material can be easily incorporated to create a tailored specification for your next project.

NATSPEC packages are supplied on a subscription basis and are updated every April, in line with the NCC, and October. The following package are designed for architects, interior designers, landscape architects, structural and building services engineers, and home building designers.
