It was originally envisaged that the main quadrangle would be flanked by two terraces of houses, one to the east and one to the west, providing accommodation for several of the Commissioners whose offices were based there. It is not certain at what pace the rest of the construction progressed, but it is clear that the outbreak of war with France in 1793 caused delays through lack of money. Chambers died in 1796, whereupon James Wyatt took over as architect. In the end, only the western terrace was built and by 1801 the building was deemed to be complete, at a cost of £462,323.
