这座三单元的住宅楼是由旧金山一个普通的单户住宅创建的，该住宅多年来一直受到忽视。在现有的建筑上面增加了两层，并在车库后面增加了一个双高的后部，形成一个五层的结构。
This three-unit residential building is created from an ordinary single-family home that was suffering from years of neglect in San Francisco. Two stories were added above the existing building and a double-height rear addition was included behind the garage, creating a five-story structure.
该地块位于双峰山的东侧，由于其下坡的方向，从建筑后部的上四层可以欣赏到市中心的全景。该项目为缺乏更多住房选择的城市带来了亟需的密度，并位于公共交通线路上，可以方便地前往城市的其他地方。
The site is located on the east side of Twin Peaks and enjoys sweeping views of downtown from the upper four floors at the rear of the building due to its downslope orientation. The project brings much-needed density to a city starved for more housing options and is located on a public transportation line allowing for convenient access to the rest of the city.
一、二层为低层单元，三层为中层单元，四、五层为高层单元。 下层单位通向一个由树木、碎石和一个适度的混凝土庭院组成的最小花园空间。 夹层的卧室空间向下看是一个双层高的客厅和厨房。 位于建筑前部的中间单元的卧室采用了战略性的垂直窗户，以创造一种与下面的街道相隔的隐私感。
The first two levels contain the lower unit, the third level contains the middle unit, and the fourth & fifth levels contain the upper unit. The lower unit opens onto a minimal garden space of trees, gravel, and a modest concrete patio. The mezzanine bedroom space looks down onto a double-height Living Room & Kitchen volume. The middle unit’s bedrooms at the front of the building incorporate strategically placed vertical windows to create a sense of privacy from the street below.
中间单元的后部通向一个宽敞的景观平台，客厅空间的天花板高度增加。 上层单位在四楼安排了一个客厅/餐厅/厨房空间，一个卧室和一个办公室。 五楼的顶楼有一个主人套房，坐落在城市的上空。 每天早上醒来，都会看到一个真正宏伟的景象。
The rear of the middle unit opens up to a generous view deck with the Living Room space containing added ceiling height. The upper unit is organized with a Living/Dining/Kitchen space, a bedroom, and an office on the fourth floor. The fifth-floor penthouse contains a Master Suite perched above the city below. A truly magnificent sight to wake up to every morning.
前面的立面是由钢框架和铝窗组成，钢框架内是整体彩色的水泥抹灰。 上层的玻璃数量增加，作为对下面街道的隐私要求的回应。 内部空间的窗帘和胡桃木饰面为原本教化的外部结构增加了温暖和变化的层次。
The front elevation is a composition of steel frames with aluminum windows and integrally colored cement plaster infilling the steel framework. The number of glazing increases at the upper levels as a response to less privacy required from the street below. Sheer curtains and walnut wood veneer at the interior spaces add layers of warmth and variation to an otherwise taught exterior massing.
建筑的垂直循环是由一个共享的外部楼梯和单元内的私人内部楼梯组成的。 人们通过入口花园的钢/木门进入建筑，进入外部的穿孔钢楼梯。
Vertical circulation through the building is a combination of a shared exterior stairway and private interior stairways within the units. One enters the building via a steel/wood gate at the entry garden, opening onto an exterior perforated steel stair.
