规划用地是轻井泽的一个别墅区，大约在50年前开发。周围绿树成荫，每块地约为1000平方米，建筑与土地的比例为20%。房屋分散在一起，与地块边界有一定的距离，这是轻井泽独有的特点。

The planned site is a villa area in Karuizawa that was developed about 50 years ago. Surrounded by trees, each lot is approximately 1,000 m2, and the building-to-land ratio is 20%. The houses are scattered at a good distance from each other with the setback from the boundary of the site, which is unique to Karuizawa.

该地区原本是一个度假区，但现在常住居民越来越多，并不是所有的房子都关着百叶窗一字排开，但你可以从树叶、动物和鸟儿的鸣叫声中感受到人们的存在。该地区是著名的避暑胜地，夏季凉爽而潮湿，冬季严寒。

The area was originally a vacation home, but now the number of permanent residents is increasing, and not all the houses are lined up with their shutters closed, but you can feel the presence of people with the sounds of leaves in the trees, animals, and birds chirping. The area is famous as a summer resort, with cool but humid summers and bitterly cold winters.

这个地方的各种条件不能用一个词来概括，那就是 “外面”。为了保证一个与周围环境连续的生活空间，在书店周围搭了一个棚子，在棚子外安装了一个平台和屋檐。外侧的土层被收回，安装了内侧的土层，边界线是多层次的，便于根据情况选择和抛弃外部因素。

It is a place with a wide range of conditions that cannot be summed up in one word, “outside. In order to secure a living space that is continuous with the surrounding environment, a shed is placed around the bookstore, and a deck and eaves are installed beyond the shed. The outer earth floor is retracted and an inner earth floor is installed, and the boundary line is multi-layered, making it easy to select and discard external factors according to the situation.

该结构采用刚性框架结构，以减少抗震构件的数量，从而提高修改的自由度。一旦只准备了最低限度的框架，客户就会根据不时的变化，拿起各种东西继续修改。我们认为，如果把建筑看作是伴随着时间的流逝和日常生活的变化的东西，而不是为完成而建造的东西，就可以使建筑更加持久。

The structure is constructed with a rigid-frame structure to reduce the number of earthquake-resistant elements, thereby increasing the degree of freedom for modification. Once only the minimum framework is prepared, the client will pick up various things and continue to modify them according to the changes from time to time. We thought that architecture could be made more long-lasting by considering it as something that accompanies the flow of time and changes in daily life, rather than as something that is built for completion.
