The Manor House at Stan Hywet Hall & Gardens had water damage and mold problems in the 1990s. A small stream would flow through the basement because of poor drainage, causing plaster to crumble and other damage to the estate. In addition, the wall and balustrade that formed the outer boundary of the West Terrace also suffered water damage. Instead of just fixing the water damage and removing the growing mold, those who managed the estate saw the problem as an opportunity to make big improvements.
