Upon the death of his father in 1762, Hatch inherited his fortune and took on his agenting work. In 1768, he became
seneschal of the
Liberty of St. Sepulchre, acting as agent for the land belonging to the
Archbishop of Dublin attached to his palace in Kevin Street. This gave Hatch a central position in Dublin planning. At the time the centre of the city was shifting eastward. This followed the building of the
Royal Exchange in 1769 and the positioning of the
Custom House in 1774. It was the period of the
Wide Streets Commission and the construction of many of Dublin's characteristic
Georgian streets. Having secured land from the
Liberty, Hatch laid out a plan for a new street running from
Stephen's Green towards the
Circular Road to the south. It was laid out from 1777, and first appears on maps in 1784. By 1791, he had extended the street to its full length. He lived at Number 40, and sold Number 17 to Judge
John Scott. He also developed the adjacent Hatch Street, which runs from Harcourt Street to Leeson Street. Hatch was elected to the
Irish House of Commons for the
constituency of Swords in the 1768 Irish general election. He lost the seat in the 1776 election, but resumed it from
1783 until 1790. He served as secretary to the
Revenue Commissioners, director of the
Grand Canal Company and as a member of the board of governors of the
Dublin Workhouse at stages through his career. ==Personal life==
