架构师提供的文本描述。当地一位开发商要求肯纳利建筑与规划公司(KennerlyArchitecture And Planning)在一片曾经空置的旧址上设计三套新的共管公寓。该网站位于两条较小的街道的T交汇处，其尽头是一条长达一街区的景观，可以俯瞰到今天的杜洛雷斯任务塔和远处的双峰塔。这座建筑重新诠释了旧金山的精致都市主义，将其描绘成一系列从街道到宫廷的形象城市空间，通过透明的多层联排住宅，到街区中的花园和露台。

Text description provided by the architects. A local developer asked Kennerly Architecture and Planning to design three new condominiums on a formerly empty lot that once housed San Francisco’s original Mission Dolores. The site is located at the T intersection of two smaller streets, where it terminates a block-long vista and commands views up to the towers of the present-day Mission Dolores and Twin Peaks in the distance. The building reinterprets San Francisco’s fine-grain urbanism as a sequence of figural urban spaces leading from street to court through transparent multilevel townhomes to midblock gardens and patios.

主要的设计限制是，既要对共享同一包裹的改造后的历史联盟大厅保持敏感，又要对通往下面停车的共享通道保持敏感。解决方案选择了这中间的空间，作为一个共同的入口长廊和法院，而建筑延伸了一条宽阔的悬臂，出现了一个繁荣的海湾窗口，重新诠释联合大厅的传统海湾窗口，以当代的方式。

The primary design constraint was the need to remain sensitive both to the converted historic Union Hall that shares the same parcel and to the shared-access driveway that leads to parking beneath it. The solution co-opts this in-between space as a common entry promenade and court, while the building extends out and over with a broad cantilever, emerging as an exuberant bay window that reinterprets Union Hall’s traditional bay window in a contemporary manner.

在内部，这座建筑分成两部分，中间有一个花园入口处。一条走道连接着两卷书：一栋四层的联排别墅在前面，两层楼高的单元在后面堆叠在一起。所有这三所住宅都有复杂的地段，以适应自己的情况：街道大厦(Street House)有双高的体积，前面有露台，花园大厦(Garden House)向后院溢出，天空大厦(Sky House)的队伍一直延伸到宽阔的甲板上，可以看到整个城市的景色。

Internally, the building breaks into two volumes with a garden entry court in between. A walkway connects the two volumes: a four-story townhouse in front and two two-story units stacked on top of each other in back. All three homes have complex sections that respond to their situation: the Street House with its double height volumes and planted terraces in the front, the Garden House spilling out to the rear yard, and the Sky House above with its procession up to a broad deck with views across the city.

窗户是深凹的，以赋予正面的深度和纹理，并涉及到历史建筑隔壁。带肋玻璃在需要的地方提供隐私。这些卷是一种高度耐用的白色塑料甲板材料，与之相反，广泛使用染色木材，包括桃花心木门在入口处。外墙折叠起来，成为屋顶的一种元素。在屋顶水平的大型钢格子提供阴凉，而庭院和街道的慷慨种植创造了热带的感觉。装饰性金属门提供通往外部楼梯的通道。

Windows are deeply recessed to give the facades depth and texture and relate to the historic building next door. Ribbed glass provides privacy where needed. The volumes are clad in a highly durable white plastic decking material, counterpointed by the extensive use of stained wood, including mahogany doors at the entries. The exterior walls fold up and over to become a roof element. A large steel trellis at the roof level provides shade, while generous plantings in the courtyard and along the street create a tropical feel. Ornamental metal gates provide access to the exterior stairways. 

该项目占用了一个交通丰富的混合使用社区，在那里步行或骑自行车是首选的交通方式。庭院提供多方面的灯光和交叉通风，并尽量减少条件的公共空间。人行道、车道和内院都是透水的，允许水渗透到当地的沙土中。播种机和绿色屋顶也能留住雨水。广泛的遮阳窗口允许访问视图，而无需主动冷却。其他可持续的设计元素包括地板辐射采暖，地板制造快速生长的木材，低VOC完成，节水装置和灌溉系统，以及节能照明。

The project occupies a transit-rich mixed-use neighborhood where walking or biking is the preferred mode of transportation. The courtyard provides multiple light aspects and cross ventilation and minimizes conditioned common space. The sidewalk, driveway, and inner court are pervious, allowing water to percolate into native sandy soils. Planters and green roofs detain rain water as well. Extensive shading of windows allows access to views without active cooling. Other sustainable design elements include radiant underfloor heating, flooring manufactured from rapid-growing woods, low-VOC finishes, water-saving fixtures and irrigation systems, and energy-efficient lighting.
