ARTICLE 30: PROPORTIONING SYSTEMS IN PRACTICE - Putting It Together



Ching says: Don't just know proportion systems, use one consistently through project.

Steps to use system:

1- *Choose module:* In Egypt, choose 60cm or 30cm or 10cm. 60cm is best for residential (ceramic, block). 30cm for detailed. 10cm for precise.

2- *Apply to grid:* All dimensions multiples of module. Wall length 360cm (6x60), not 350cm. Room 600x400cm, not 620x410cm. Structure grid 600x600cm, not random.

3- *Apply to facade:* Window width module, spacing module. If module 60cm, window 120cm wide (2x60), spacing 60cm, looks ordered. If random widths, looks chaotic even if same area.

4- *Apply to section:* Floor heights module. Ground floor 360cm (6x60), upper 300cm (5x60). Ratio 6:5, harmonious.

Result: Zero waste, faster construction, visual harmony, easy coordination. Contractor loves you because no cutting.

Example of failure: Architect designs 3.33m room. Block 20cm, needs cutting every course. Ceramic 60cm, needs 33cm cut, waste. Ceiling 60x60, needs cutting. All trades waste time and material. Good proportion = good business.

Ching's final warning: Proportion system is tool, not prison. Once system established, you can break it intentionally at one or two places for emphasis - entrance wider, courtyard different. Break stands out because system exists.

For Instagram: Before/after - random dimensions vs modular dimensions - same plan, second looks calmer, costs less. Show waste % - random = 15% waste, modular = 3% waste. Clients and contractors both save, share heavily.

This ends Chapter 6 - Proportion & Scale. Master this, and your buildings feel right even before finishes.
