Infrastructure investment is finite.

When delivered through inefficient typologies, cost per dwelling increases.

The 1 → 3 model is straightforward:

One detached dwelling
Converted into three compliant dwellings
Within the same height envelope

Supply metrics often measure dwelling approvals.

Ownership metrics measure stability.

These are not the same thing.

Public discourse often assumes density equals height.

This is incorrect.

Density is yield per hectare.

Height is a visual outcome.

The two are not synonymous.

Queensland’s affordability gap is not a mystery.

It is arithmetic.

When land costs rise, infrastructure charges increase and build baselines reset, detached housing on conventional lot sizes becomes structurally inaccessible to median-income households.
