从A到Z的房子提出了一个替代传统方法来扩展一个过时的旧金山住宅。栖息在金门高地的山坡上，一个适度的单层1934年开发商的乡土结构，空间有限，未能利用苏特罗塔、金门公园、索萨利托和海湾的广阔视野。
The A-to- Z House proposes an alternative to conventional approaches for expanding an outmoded San Francisco home. Perched on a hillside in Golden Gate Heights, a modest single story 1934 developer vernacular structure had limited space and failed to take advantage of expansive views of Sutro Tower, Golden Gate Park, Sausalito, and the Bay.
但是，”从A到Z “的策略并没有取代或仅仅附加到现有的结构上，而是抓住了现有的形式–缩放、重复和操纵现有的物体，使之成为一个有背景的结构集合，构成了一个沉浸在周围环境中的动态住宅。
But rather than replacing or merely attaching to the existing structure, the A-to- Z strategy seizes upon the existing forms – scaling, repeating, and manipulating found objects into a contextual collection of structures comprising a dynamic home immersed in its surroundings.
一个新的坡屋顶结构被插入到现有的起居室吧台的山脊线上，从街道后退以减少质量，并依偎在现有的屋顶上以建立一个低水平线。这个基准线的特点是一个带状的可操作窗户，包裹着建筑的两个角落，以利用关键的视野，并以锯齿状的窗户系统和加厚的金属边缘为重点。在内部，楼层和天花板高度的变化为每个空间提供了体验这一地平线的不同方式，从广阔的视野到私人观景台。
A new gabled roof structure is inserted at the ridgeline of the existing living room bar, stepping back from the street to reduce mass and nestling into the existing roof to establish a low horizon line. This datum is characterized by a ribbon of operable windows that wrap two corners of the building to take advantage of critical views, accented by to a sawtooth window system and thickened metal edge. Inside, variations of the floor level and ceiling height provide different ways to experience this horizon in each space, from sweeping vista to private lookout.
当新的坡屋顶结构到达精心设计的梯田后院时，它在餐厅周围扭曲并向下包裹。沿着扭曲的Z字形轴线（水平和垂直交替）的转弯，与现有的房子稍稍分开，利用光带和天花板的衔接，在类似的形式中创造出有意义的差异。
As the new gabled structure reaches the carefully terraced back yard, it twists and wraps down around the dining room. This turn along a torqued Z-shaped axis (alternately horizontal and vertical) is held ever so slightly apart from the existing house, using a band of light and the articulation of the ceiling to create meaningful difference out of similar forms.
