 Georgian houses aimed at the prosperous middle class were constructed around the square, some of which survive such as Nos 12–14, which are Grade II listed, on the eastern side of the square.A plan of Birmingham by Thomas Hanson in 1778 shows that most of the Newhall estate had been laid out in a grid-like pattern from St Paul's Church.The plan also showed that two pools, Great and Little Pool, had been filled in and the brook that fed them had been canalised.
