The owners toured this home, which surrounds a mature tipu tipu tree, while visiting relatives for the day. The brick is original to the 1947 construction.

One of the Living Vehicle’s most popular features is its self-supporting deck, which serves as an extension of the indoor living space and can be easily lowered or raised with a garage door–style support spring. The updated deck is now rated for 1,500 pounds.
