BODY TEXT

Architecture is the learned game, correct and magnificent, of forms assembled in the light. The materials of city planning are sky, space, trees, steel and cement, in that order and in that hierarchy.

Alerts & Notes

Drawing notes and revision annotations. Each type uses a hatched left edge in its respective color, mimicking section-cut hatching conventions.

General Note
All dimensions are in millimeters unless noted otherwise. Do not scale from drawings. Verify all dimensions and levels on site before commencing any work.
Approved for Construction
This drawing set has been reviewed and approved for construction issue. Contractor to proceed in accordance with specification sections 03 30 00 through 05 12 00.
Design Development
Areas marked are subject to further design development. Coordination with structural engineer required before next issue. Hold dimensions are indicative only.
Revision Notice -- Rev. 03
Meeting room G.03 area reduced from 32.0 m² to 24.0 m² to accommodate revised corridor width. All affected partition dimensions to be updated.

Design Principles

The governing rules of this design system, drawn from the discipline of architectural drafting.

Line Weight Hierarchy

Every line has a weight and a purpose. Profile lines define the cut plane. Projection lines convey depth. The hierarchy of weight creates spatial understanding from a flat surface.

Precision Over Decoration

Ornament is information. Hatching denotes material. Dashed lines indicate hidden structure. Every visual element serves a communicative function. Nothing is decorative for its own sake.

The White of the Paper

White space is not empty. It is the void of the room, the volume of the atrium, the expanse of the site. Respect its presence as you would respect silence in music.

Convention as Language

Architectural drawing is a language with centuries of convention. Red means revision. A circle with a number is a detail reference. Follow the conventions. They are the grammar that makes drawings readable.

Scale and Proportion

Everything is drawn to scale. The spacing system is a modular grid. Components relate through consistent proportional relationships, just as rooms relate to buildings.

Annotation as Clarity

A drawing without dimensions is a picture. A drawing with dimensions is an instruction. Dimension lines, leader notes, and scale bars transform composition into buildable information.
