虽然典型的房屋体积会将一片狭小的空地分叉到前院和后院，但在这里，尴尬的窗户直接开在附近的空地上，而在这里，U形的设计允许第三个室外空间穿透大楼的中心，在寒冷的冬季，在不牺牲邻居隐私的情况下，提供南方的暴露空间。进入这两个住宅单元的主要通道是通过中间庭院-而不是建筑物的外墙-而汽车通道则位于建筑物北部的一个单独区域。

Whereas the typical house volume bifurcates a narrow lot into front and back yards, with awkward window openings directly onto neighboring lots, here the U-shaped plan allows a third outdoor space to penetrate the building’s center, providing southern exposure during the cold winter months without sacrificing privacy from neighbors. Primary access to both dwelling units occurs through the middle courtyard -- as opposed to the building’s façade – while automobile access occupies a separate zone to the building’s North.

对建筑形式的进一步操纵创造了一套对角线“折痕”和“切口”，将内部区域分成流动的、相互关联的区域(传统的墙壁隔墙仅限于卧室、浴室和辅助支撑空间)。因此，室内被整合成一个视觉继电器，通过房子本身的体积将所有外部空间连接起来：前院、后院和室内庭院成为居住空间的延伸。在部分，房子的上层沿着一条小溪向街道走去，而一系列缓缓的层叠屋顶进一步模仿了倾斜的景观，同时也让光线进来了。

Further manipulations of the building’s form create a set of diagonal “creases” and “incisions” that separate areas of the interior into fluid, interrelated zones (Traditional wall partitions are limited to bedrooms, bathrooms and secondary support spaces.). The interior is thus incorporated into a visual relay that connects all exterior spaces through the volume of the house itself: front yard, back yard, and interior court become extensions of living space. In section, the upper floors of the house step down toward the street, which runs along a stream; and a gently cascading series of roofs further mimics the sloping landscape, while letting in light.
