一个大房子。一座业主自用的出租公寓楼通常在出租单元之上有其业主的顶楼。初濑美田也是一个拥有多个出租单元的自住物业，但其空间组织却大不相同。由于该地区的重建项目，业主的家庭被迫搬出他们以前的住所，他们需要一个能够适应家庭结构和社会变化的新家。

A big house. An owner-occupied rental apartment building typically has its owner’s penthouse above the rental units. Hatsuse Mita is also an owner-occupied property with several rental units, but its spatial organization is much different. The owner’s family was forced to move out of their former residence due to the area’s redevelopment project and they needed a new home that can adapt to changes in their family structure and society.

因此，我们提出了一个计划，即每个单元都有独特的平面图，可以作为出租单元提供，也可以作为家庭住宅的 “独立房间 “对待，而不是供全家人共同居住的住宅。在这个非等级化的计划中，家庭可以从一个单元搬到另一个单元，这取决于他们在未来过渡时需要的空间类型。

So instead of a residence for the whole family to live together, we proposed a plan in which every unit has a unique floorplan and can be offered as a rental unit or treated as an “individual room” of the family’s residence. In this non-hierarchical plan, the family can move from one unit to another, depending on the type of space they need at the time of transition in the future.

私人和公共空间既不封闭，也不相互开放，而是作为断线的边缘碎片组织起来。初濑美多是一个 “大房子”，在这个意义上，居住者可以保持与家人在以前的房子里享受的同样的隐私和亲密程度。

Private and communal spaces are neither closed off nor open to each other but organized as edge pieces of a broken line. Hatsuse Mita is a “big house” in the sense that occupants can maintain the same privacy and intimacy level that the family enjoyed in their former home.

内部和外部的混合。该地块位于一条主干道上的大型住宅楼和一个低层木屋区之间。考虑到这两个区域之间质地和尺寸的高度对比，我们测算了一个中间的结构规模：用310毫米的方形柱子搭建一个框架，间隔1350毫米。在这个简单结构的中心，一个开放的 “Meguri-doma “连接着所有的楼层。”开放式露台”、”内部露台 “和 “生活空间 “以不同的模式放置在它的周围，以混合整个结构的内部和外部。我们的目的是为这个分层的网状建筑增加一种通风的感觉。

Mixing inside and outside. The site is situated amongst large-scale residential buildings along a major road and an area of low-rise wooden houses. Considering the high contrast of texture and sizes between these two areas, we gauged an intermediate structural scale: a frame built with 310mm square columns placed 1350mm apart. Set in the center of this simple structure, an open “Meguri-doma” connects all levels. “Open terraces, ” “Inner terraces, ” and “Living spaces” are placed around it in various patterns to mix inside and outside throughout the structure. We intended to add an airy feel to this layered net-like architecture.

Meguri-doma. “Meguri-doma（一个有盖的楼梯间/公共走廊）”的设计是为了容纳阳光，让微风流过内部的露台和生活空间。通过这样做，楼梯间成为一个具有室内和室外氛围的流动空间。

Meguri-doma. “Meguri-doma (a covered stairwell / common corridor)” is designed to hold sunlight and allow the breeze to flow through the inner terraces and living spaces. By doing so, the stairwell becomes a fluid space that has both indoor and outdoor atmospheres.

在每个着陆区都有一个长椅，这表明可以将该空间作为第二客厅或学习空间的替代用途。公共露台上配备了一个户外厨房。13个形状各异的公寓单元与共享空间一起构成了一个多面体，使居民能够在建筑中找到适合他们在特定时刻所需的空间。

There is a bench in every landing area, which suggests alternative use of the space as a second living room or a study space. The communal terrace is equipped with an outdoor kitchen. Thirteen apartment units in various shapes, along with the shared spaces, form a multi-faceted volume, allowing residents to find a suitable space in the building for what they need at a particular moment.
