ホモテナシ

• the 草案 style is not terribly new, the first reference we find in Nara period (~700 AD), in Empress Genshō's following poem:

This chamber built with barked wood
Brought from the grove nearby
And thatched with obana strems
Shall stand a thousand years

• More concretely, in Sakai of Jōō's time, the concept of a mountain hermitage in the city was already popular (see here)
• Jōō built the first 4.5 畳 tea room: 同仁斎（どうじんさい）
• 利休's 待庵 obviously the most famous example.

• 織部（おりべ） then coined the 燕庵（えんなん）style: 3.75 畳, adding one mat for the attendants, and some connected rooms.

• 遠州（えんしゅう）reintroduced 書院 feel, for example in 密庵（みつあん）
• 有楽（うらく）created 如庵（じょあん）

→ No body continued 利休's style
