Mountjoy square was developed as part of this third development phase. An early plan and elevation, known then as "Gardiner Square" was drawn up in 1787 by Thomas Sherrard, surveyor to the Wide Streets Commissioners. Gardiner and Sherrard had an ambitious vision for the square. It was on high ground, so all streets off it led downhill. It overlooked The Custom House and was connected to it by Gardiner Street. The plan included a rebuilt St. George's Church in the centre of the park. The original West side plans show a palatial stone-clad street frontage with a terrace of brick residential houses behind the cladding. A less ambitious compromise of red-brick façades, consistent with other nearby streets, eventually prevailed.
