The city of Itsuura, located in the north part of Ibaragi prefecture, has known as a prosperous fishery. Tenshin Okakura * who was enamored by the scenery of the coast line of Itsuura and loved the place as his final abode. There are some historic architectures such as Rokakudo ** designed by Tenshin and Tenshin Memorial Museum of Art.
The owner of the house is a fisherman. His ancestor was a sailor attendant working near Tenshin. In those days, it was saying that Tenshin left a message "Fishermen do plant trees in mountains". The story of the project starts with planning to make full use of the site in the mountain inherited from his ancestor and design the house.
Tenshin Okakura * (also known as Okakura Kakuzo) was a Japanese scholar who contributed to the development of arts in Japan. Outside of Japan, he is mainly remembered today as the author of "The Book of Tea".
Rokakudo 是一处俯瞰Itsuura海的六角形木结构静居。 “V”字外形充分利用土地。因为场地面向南面倾斜，一开始充分评估，对场地做出规划很重要。建筑师制定了一项规划，不去开发土地，而是根据现有场地的情况来设计，尽可能保护树木。
建筑师首先勘查山坡，然后根据数据建构外形，使一些平坦的表面显现，并把它们联结起来。点变成线，线变成面，重复这些步骤，最终找到建造房屋的合适地点，同时充分利用场地环境。住宅的规划看起来像展开的“V”字形，两翼分别设计用于不同的居住环境。
Rokakudo is a hexagonal wooden retreat overlooking the Itsuura sea.
"V" makes full use of the land
Because of the south-facing steep site, to begin with evaluating to plan the site was very important issue.
Not to develop the land, we set a rule to follow the shape of the current site condition and preserve the trees as possible as we can.
At first to survey the mountain slope, second modeling the shape from data, and some flat surfaces were emerged and connected them. Points became lines and lines became surfaces, repeating these processes, we could finally find out the suitable location to plan to build the house, and it also makes full use of environment of the site. The plan of the house looks like spreading shape of "V", and two wings are designed as different living environments.
