本项目的客户是一对环境科学家夫妇和他们的两个儿子，这次，他们要举家从奥克兰山（Oakland Hills）搬迁到气候更加宜人的Orinda。值得一提的是，客户非常重视可持续发展，希望这座住宅能够达到年净零能耗的能源标准，因此，建筑师将这一能效方面的考量融合进了整个设计过程。项目基地位于山脚下，旁边是一条季节性的小溪，这里曾是一座建于1954年的农舍，此次，设计团队将其改造为了一座三居室的住宅建筑。经过对场地和原建筑的考察，设计团队发现原有的建筑建构和土壤的品质并不适合改造和加建，多方讨论和沟通后，设计团队决定重新寻找项目基地。原建筑的附近生长着一棵郁郁葱葱的山谷橡树（Valley Oak），设计团队便将其树荫下的一部分原有基地划为本住宅的基地。 The clients are a couple of environmental scientists who, along with their two sons, relocated from the Oakland Hills to the warmer climate of Orinda. Their commitment to sustainability, including a request for net-zero energy performance annually, was evident in their thinking throughout the design process. A three-bedroom program began as a remodel of a 1954 ranch house at the foot of a hill next to a seasonal creek. After finding the existing structure and soils to be unsuitable, the direction settled on reusing the existing footprint under the shade of a Valley Oak that had grown up close to the original house. 
经过上述的一番修整后，原建筑中用于结构支撑作用的、由混凝土围合而成的壁炉空间被保留了下来。这一举措使得额外的评级变得可有可无，而新住宅也可以像原有建筑一样，保有与老橡树之间的亲密关系。 The surviving portion of the original house is the fireplace which was wrapped in concrete and utilized for structural support. This made additional grading unnecessary and allowed the new house to maintain the same intimate relation to the old oak. 
业主一家希望能有一个开放式的居住空间，同时能够直接通向室外景观。因此，设计团队在室内空间中设计了一个夹层空间——家庭起居室双层通高，主卧和书房则位于厨房和小憩空间上方的夹层空间中。下层空间中，次卧沿着走廊排布，限定出一个位于厨房和家庭起居室之间的室外用餐区。 The family desired an open living layout that connected directly to the landscape. A mezzanine plan evolved with a double height family space nested with a master bedroom and study stacked above the kitchen and nook. Downstairs, secondary bedrooms along an extendable hallway, wrap an outdoor dining area situated between the kitchen and family room. 
透光的遮光隔板被安装在上层空间的外立面上，阻挡了炎炎夏日中过于强烈的正午时分的阳光。对于室内饰面来说，选择木材作为主材料则有利于隔音结构、天然的橡木天花板和墙体等的建造。通过有限的材料，设计团队打造出了一个具有良好景观视野的、轻松安逸的居住环境，置身于其中，住户能够全身心地沉浸在自然环境中。由此，住户与自然之间，有了一条无形的、却联系紧密的纽带。 A screened pacing deck for long phone calls shades the upper level from afternoon summer sun. For interior finishes, single use material selections produced acoustically insulated, unfinished oak ceilings and walls. The sum total of the limited and landscape-driven materials presents a relaxed and quiet built environment that allows the senses to focus on the natural environment. A haptic connection to the rhythms of our planet is evident. 
由14号柯尔顿耐腐蚀钢材打造而成的防雨隔板使得住户不需要花费额外的时间和精力去维护住宅的外立面。高水平的保温隔热结构和玻璃外墙结构降低了建筑在采暖和降温时所需要或所释放出的热荷载。8.1kW的光伏系统为居住空间提供了一种可再生的能源，更为重要的是，随着居住年限的增长，该系统将产生越来越多的电能。走廊尽头的屋顶处设有专门的雨水收集结构。地下的水箱收集和储存的水则可以用 |
