01What the drawings show
Frame, module, connection
The library is organised around the three things a project team needs to check first: how the frame works, how the module is completed, and how it connects to the base.
Factory-completed modules
Kitchen and bathroom pods, closed-cell insulation, glazing and finishes installed before the module leaves the plant.
Connection and base details
Column-base anchors, isolation layers, anchor spacing and design pull-out values documented for review.
02Case references
Three light-steel references, clearly labelled
Each case is tied to a drawing set in the library. Images are illustrative; the drawing scope and project status are stated in the notes.

Drawing indexes are published for capability review only. Files are not loaded or downloadable on this page; issued sets are not for construction, and dimensions, codes and connections must be verified for each project.
04How to use the library
Reference first, project verification second
The drawings help a project team understand the system and ask better questions. They are not a substitute for a project-specific design package.
Reference only
Do not build from these sheets. Dimensions, loads and details change with site, code and module configuration.
Project-specific scope
Full sets, stamped drawings and connection calculations are released after the project brief is confirmed.
Clear status labels
Drawing reference, permit reference and detail reference are separated; no sheet is presented as a completed LEGEND project.
