在空间有限的场地上设计房屋时，我们最近一直在探索在一系列阶梯式地板上逐渐延伸的连续地板安排的可能性。与其使用墙壁和不同的楼层来明确地将空间划分为不同的功能，不如通过阶梯式的楼层将所有的东西松散地连接和断开。这个想法是要在一个小房子里创造一种扩张感，这样你就会发现自己一会儿在屋顶上，一会儿又被压在地板下。
When designing a house on a site with limited space, we have recently been exploring the possibilities of a continuous floor arrangement that extends gradually over a series of stepped floors. Rather than using walls and different floor levels to clearly divide the space into various functions, everything loosely connects and disconnects from each other through stepped floors. The idea is to create a sense of expansion inside a small house, so that you would find yourself on top of a rooftop in one moment, and tucked beneath a floor in another.
这个概念在宫本的房子项目中首次成为现实。在这里，不同楼层之间的空间被留出，以创造一种漂浮的效果，允许地板被用作书桌和可以储存物品的架子。同时，这种设计让我们在视觉上强调了各个房间之间的关系。
This concept first came into reality with the project House in Miyamoto. Here, the spaces between different floor levels were left open to create a floating effect, allowing the floors to be used as desks and shelves where objects could be stored. At the same time, this design allowed us to visually emphasize the relationships between various rooms.
对于这所房子，我们在追求新的可能性的同时使用了相同的构图。由于预算的原因，结构选择了木材，由于结构的限制，楼层之间的空间是封闭的。与宫本的房子不同，房子内的能见度是有限的；只有一丝丝的空间延续到人们的视野之外。通过在矩形外壳上叠加一个旋转45°的对角线网格，我们试图创造一个简单而复杂的、地理上的、像洞穴一样的迷宫，捕捉到一个小房子里面。地板从两个不同的点螺旋式上升，在作为餐厅和厨房的楼层相遇，然后分开，最后在屋顶再次相遇。
For this house, we used the same composition while pursuing new possibilities. Due to budgeting reasons, wood was chosen for the structure, and the spaces between the floors were enclosed due to structural limitations. Unlike House in Miyamoto, the visibility within the house is limited; there is only a hint of the spaces that continue beyond one’s vision. By overlaying a diagonal grid rotated at 45° on top of a rectangular shell, we attempted to create a simple yet complex, geographical, and cave-like labyrinth captured inside a small house. The floor rises from two different points in a spiral to meet on a floor that is the dining and kitchen, and separates to finally meet again on the rooftop.
屋顶的设计是为了满足后退的规定，当这安装在一系列楼层之上时，房子虽然让人联想到传统的住宅，但却成为一个相当奇怪的多面体。
The roof is designed to meet the setback regulations, and when this is installed on top of the series of floors, the house, while reminiscent of a traditional home, became a rather curious polyhedron.
场地在一个郊区住宅区的斜坡上，被开发成梯田的地块；相邻的地层也不平整。一开始，我们考虑使用分层的构图来应对该地点的条件–这个想法最终启发了这个项目的设计。结果，十六个不同的楼层被挤在这个小房子里，在不同的方向上扩展和移动，以创造一个功能性的、像洞穴一样的基础来支持居民的生活。
The site is in a suburban residential neighborhood on a slope developed into terraced plots; the neighboring ground levels are also uneven. In the beginning, we thought about using a split-level composition in response to the conditions of the location – this idea eventually inspired the design for this project. As a result, sixteen different floors were packed into this small house, expanding and moving around in different directions to create a functional, cave-like foundation to support the life of the residents.
