Why did London use more brick construction after the Great Fire of 1666?

Following the Great Fire of 1666, which destroyed approximately 13,000 houses and a significant portion of the City of London, the city underwent a major transformation in its building practices.1

London transitioned from a city primarily constructed of wood to one built of brick specifically to gain protection against the threat of fire. Medieval cities were chronically affected by disastrous fires, and the shift to brick was a deliberate measure to enhance fire safety and prevent the recurrence of such a catastrophe. While rebuilding acts passed in 1667 and 1670 focused on street widening and the reconstruction of essential civic buildings and churches, the widespread adoption of brick became the standard for ordinary domestic construction, providing a more durable and fire-resistant alternative to the previous timber-framed structures.234
