空间的开放性/必要的空间和多余的空间
这是为一对基督徒夫妇和一个新生婴儿设计的房子。客户对这所房子有两个愿望。一个公共房间，家人、基督徒朋友和邻居可以一起学习圣经，客户可以为周日的礼拜练习风琴；户外空间，家人和访客都可以享受自然光和风，同时保持足够的隐私。
Openness of space / Necessary space and Surplus space
This is a house for a Christian couple and a newborn baby. The client had two wishes for the house: A common room where the family, Christian friends and neighbors can learn the Bible together and the client can practice the organ for Sunday services and outdoor space where both the family and visitors can enjoy natural light and wind while keeping enough privacy.
房子位于新横滨市小山顶上的一块缓坡角地。该地块曾是停车场，周围有两层楼的房子和公寓。房子被放置在场地的一部分，而另一部分则用于5个出租的停车场和2个面向2条侧街的私人停车位。现有的自动售货机被保持原样。
The house is located a gentle sloping corner lot on top of the small mountain in Shin-Yokohama. The site which had been parking lot is surrounded by two story houses and apartments. The house is placed at a part of the site while the other part is used for 5 rented parking lot and 2 private parking space facing to the 2 side streets. Existing vending machine is kept as it had been.
房子与周围环境尽可能地封闭，墙面上只有一个入口门和最小的小窗户，以保护自己不受环境影响：使用自动售货机的声音、夜间的汽车灯光、汽车尾气和使用停车场的人的声音等。房子有足够的开放感，从街道和城镇延续下来，而它对周围环境是封闭的。
The house is as closed as possible against surroundings with the wall which has only an entrance door and minimum small windows on the surface to protect itself against the environment: sound of using the vending machine, car light at night, automobile exhaust and the voice of people using the parking lot, etc. The house has enough open feeling continuing from the street and town while it’s closed against surroundings.
通常必要的生活空间（客厅、餐厅、厨房、卧室、儿童房等）在这个房子里只占一半的面积。另一方面，半室外的院子占据了房子的另一半面积。而公共房间是最大的房间。我发现在这所房子里需要大量的剩余空间（不必要的空间），以创造一个宽松的环境来接受各种访客和行动。虽然房子一般是个人居住的地方，但它也是公共和神圣的地方。
The normally necessary living spaces (living room, dining room, kitchen, bedroom, children’s room, etc.,) take only half area in this house. On the other hand, the semi-outdoor courtyard takes the other half area of the house. And the common room is the largest room. I found that a lot of surplus spaces (unnecessary spaces) are needed in this house to create an generosity to accept various visitors and action. While the house is generally personal living place, it is also public and holy place.
穿过整个天花板的木柱和主梁被涂成棕色，上面的次梁被涂成白色。主梁交接处的11个天窗投下了十字形的影子。
The wooden columns and primary beams which pass over the entire ceiling is painted brown and the secondary beams on them are painted white.11 skylights on the primary beam intersections cast cross-shaped shadows.
当面向院子的大窗户被打开时，院子逐渐与室内相连，两地之间的边界减少。这座房子既没有变成室内，也没有变成室外。
When the big windows facing the courtyard is opened, the courtyard gradually connects to the indoor and there is less border between both places. The house turns neither indoor nor outdoor.
多余的空间有时会被用来吃东西或看书，如餐厅或书房，而必要的空间则从必要中释放出来，变成了多余的空间。必要的空间和多余的空间不时地相互替换它们的角色。我愿意相信这种温和的连续的空间性是建筑应该有的。
The surplus spaces sometimes turn to be used to eat foods or read books like dining room or study room and the necessary spaces are released from being necessary and turn to surplus spaces. Necessary spaces and surplus spaces replace their roles each other from time to time. I would like to believe such gentle sequential spatiality as what architecture should be.
