Ripley was appointed after the death of Colen Campbell in September 1729. He successfully completed the hospital but to a revised design, in which the plan and elevations of the east wing of Queen Mary's Court were greatly simplified. The construction of Queen Mary's Court was made possible by an Act of Parliament in 1735 by which the 'Rents and Profits' of the estates of the Earl of Derwentwater were forfeit, to be applied towards finishing the Hospital. Many drawings in the Greenwich Hospital Album appear to be connected with decisions taken in 1735 about the final plan of Queen Mary's Court, and the form intended for walled garden areas behind each of the four courts and for a complete walled enclosure to the site within a rectangular plot roughly equivalent in size to that drawn on the block plan of c.1728, [11/2] (109/6). Hawksmoor's concern with establishing a symmetrical layout framed by Back Lane on the east and an 'Esplanade' on the west (equal in distance from the west Courts as Back Lane from the east Courts) continued to dictate the planning of the ideal layout for the completion of the hospital.
