'House with 30,000 Books' is a residence in Tokyo designed for two families with a serious yen for reading. The two dwellings are separated by a common connecting atrium with walls that are covered entirely by bookshelves, with room for approximately 30,000 books, as the name of the home suggests.
Though House with 30,000 Books is a private residence, its library-like atrium can easily house as many if not more books that a small public facility. The space is also designed like a library in terms of layout, with tables for reading and aisles that allow the families to browse through the copious tomes.
The windows of the library area are specially designed to keep the books in the house in good condition. They block out both ultraviolet light and humidity, keeping the paper from deteriorating.
