See what a caring father built in the basement of his house in order to distract his kid from running on the loose around the town.

Architect Kota Mizuishi created this very narrow triangular house in Horinouchi Japan. A husband and wife and their one child live in this truly unique house that actually has a kitchen, bathroom, bedroom, playroom and a guest space. The house is valued at around $200k.

1948 was the year when the last interior changes were made. Doug Bethel, 89, from Liverpool, refuses to change anything inside since then. Every detail is a reminder about the past and his childhood, as this was the house where he grew up with his parents and six siblings.
