Richardson spent much of his later years in his house at 25 Cottage St. in Brookline, Massachusetts, which had a studio attached to ease the strain on his health. The house fell into disrepair and was listed in 2007 as an endangered historic site. However, the house was purchased in March 2008 for roughly $2 million with an amended deed requiring that the building be historically restored. The house is on a hill, where Richardson could supposedly watch construction of the Trinity Church in Copley Square, from his second story window.
