LongHouse Reserve

Larsen set up the LongHouse Reserve as a non-profit sculpture garden and arboretum in East Hampton.[2] The reserve included his house, and was completed in 1992. It was built as a collaboration with the architect Charles Forberg, their 30th project together.[1] It has 13,000-square-foot (1,200 m2) of floorspace spread across 18 spaces and four floors.[1][3] The design is inspired by the Ise Shrine, a seventh century Shinto shrine in Japan.[1][2] He initially bought the land as a way to prevent encroachments, but, later developed a landscaped sculpture garden surrounding the house and opened it to the public
