Lever sequence
The order in which the three levers are best applied to a small home: Subtract first, then Layer, then Extend. Subtract to reveal the true space, Layer to multiply what each area does, Extend to reach what is still missing.
Reveal, multiply, reach
Run out of order and you often pay to add space you'd have found for free by subtracting first. Every lever module of this course (1 through 5) follows the sequence: Subtract → Layer → Extend.
