A Hawaiian treehouse with ocean views is on the market for $2.96 million

A home that'ss basically the adult version of your childhood treehouse is on the market for $2.96 million.

In 1975, architect Steve Au built this unique vertical home on the side of a hill in Kailua, on the island of Oahu in Hawaii.

Steve's wife, Irene, spent time tending to what she calls her "personal Eden" - a garden bearing fresh fruit like avocados, papayas, and cherries.

Now in their early 80s, the couple can no longer handle climbing four stories of stairs every day, so they decided to put their "treehouse" up for sale in October 2014.

"This house marks a major chapter in our life," Steve told Realtor.com. "And we are willing to pass this on to whoever this is that can find value in living as we do."

Originally priced at $3.8 million, the treehouse is now listed for $2.96 million. Lynn Young Soldat of Coldwell Banker Pacific Properties holds the listing.
