Many of the transformations have resulted in the loss of stunning buildings, ranging from the historically important to the architecturally significant.
The post-war era of the 20th century saw a large increase in the number of Georgian and Victorian structures being raised to the ground, as the Capital looked boldly towards the future.
But it has to be said, not all of these modern developments were welcomed by locals, and many were fiercely opposed.
