By the spring of 1729 the citizens of Philadelphia were petitioning to be allowed to build a state house. Two thousand pounds were set aside for the endeavor. A committee was formed composed of Thomas Lawrence, Dr. John Kearsley, and Andrew Hamilton with the responsibility of selecting a site for construction, acquiring plans for the building, and contracting a company for the purpose of construction. Hamilton was, along with William Allen, named a trustee of the purchasing and building fund and authorized to buy the land that would be the site of the state house. By October 1730 they had begun purchasing lots on Chestnut Street.
