Those involved in the revival had to decide whether to restore the building to such seismic fitness that the house would be only a replica of its original form or to maintain the integrity of Wright's original vision while adding just enough seismic reinforcement to make it safe. In the end, much of the house's concrete slab floor was replaced with a new one, designed to replicate the original with its hexagonal detail. Underneath that floor, engineers installed a system of concrete beams that connect the central chimney and retaining walls. Each of the home's three chimneys was reinforced with steel beams and concrete. Plywood was used to strengthen the roof and some of the walls.
Ties now connect the roof to the walls and the chimneys.
The restoration has been financed largely with private contributions. Additional funds will be needed for finishing touches.
