The first rebuilding on the ancient site was designed by architect James Paine and carries the inscription across the front roofline, Except the Lord build the house: their labour is but lost that build it. The house was vastly enlarged in 1832. Adare remained the home of the Earl of Dunraven until it was sold in 1987. The Dunraven family now reside in Kilgobbin House, Adare. The house was purchased by Irish-American businessman Tom Kane and converted into the Adare Manor Hotel. A golf course, the Adare Golf Club was added alongside the Adare Manor Golf Club in 1995.
The house is set on a magnificent 840 acre estate and now operates as a five star hotel, featuring the [[Adare Golf Club], Elemis Treatment Roooms, Townhouses and Villas on the rest of the resort. President Bill Clinton stayed in Adare Manor in September 1998. The Manor was voted Ireland's Leading Hotel in the 2006 World Travel Awards
It hosted the Irish Open in 2007 and it is hosting it again in 2008 and 2009
