La Casa是关照无家可归者的一个新原型，它重新定义了关照无家可归者的模式，这种设施以前通常在华盛顿特区生产消毒机构。La Casa不是收容所——人只能在夜间居住，白天被要求离开；La Casa是为40名男性提供永久、全天候的支持性住房。由于每个单元都设计为单人居住，永久性住房为居住人提供了稳定性和可预见性，他们重新投入到日常生活中。永久支持性住房（PSH）是从全日制关照过渡到独立生活的重要一步。项目的市政业主要求La Casa的设计品质要超过相邻市价公寓。
La Casa is a new prototype for homeless care and redefines a homeless care paradigm that typically produces antiseptic institutional facilities in Washington DC. Rather than function as a shelter - where clients are housed only at night and asked to leave during the day - La Casa provides permanent, round-the-clock supportive housing for forty men. With each unit designed as a single-person efficiency, the permanent housing provides stability and predictability for the men as they re-immerse themselves in day-to-day living. Permanent Supportive Housing is a significant step in the transition from full-time care to independent living. The project was fortunate in having a municipal client that requested the design quality of La Casa exceed that of the adjacent market-rate condominiums.
La Casa是华盛顿哥伦比亚特区首个永久支持性住房设施，也是哥伦比亚特区和总务部重新定义无家可归者社区住房概念的重要里程碑。
La Casa is the first permanent supportive housing facility in Washington DC and an important milestone for the District of Columbia and the Department of General Services in its efforts to redefine the concept of housing for the homeless community.

无家可归不是一种经历——它是连续发展的事情。稍好点的情况是，人在收容所系统中度过了两天时间。最极端的情况是那些长期无家可归的人，并且身患致残性疾病。La Casa是这些长期无家可归者的家园。
Homelessness is not one experience - it is a continuum. At its least extreme are people that spend a day of two in the shelter system. At its most extreme are the chronically homeless, people who have been homeless for a long time and suffer from a disabling condition. La Casa is home to people with histories of chronic homelessness.
每个居住单元内部设计注重空间使用效率和耐用性。受造价更高的工作室Loft公寓的启发，每个住宅单元都提供了落地式活动窗，以实现自然采光和通风。这些单元功能简单，将混合生活、餐厅和厨房空间与睡眠区相结合。
Unit interiors are designed for space efficiency and durability. Inspired by more costly studio loft apartments, each dwelling unit provides floor-to-ceiling operable windows for natural daylighting and ventilation. The units offer functional simplicity, coupling a hybrid living, eating, and kitchen space with a sleeping niche.

外露混凝土和竹子制成的温暖耐用的地板与洁白墙壁、精致的灰色系厨房相得益彰。与许多支持性住房项目里的高效公寓或单人房（SRO）不同，La Casa 旨在在集体住房的背景下培养个性化身份。
Warm and durable flooring of exposed concrete and bamboo complements crisp white walls and a refined gray kitchen. Unlike the efficiency units or single room occupancy units found in many supportive housing projects, La Casa is designed to foster individualized identity within the context of collective housing.
La Casa的建筑体量开建在街道上并创造了一个开放而吸引的入口。玻璃层提供了进入内部的视觉通道，加强了建筑在社区的可达性，同时也提供了安全。
La Casa’s building mass is carved at the street level to create an open and inviting entry. Layers of glazing provide visual access to the interior, reinforcing to the community the accessibility of the building’s programs, while also providing security.

外墙面的规律变化将城市天际线的固定形式与城市街道活力融合。La Casa是一个固定、可靠的存在，它仍置于周围城市的生活和动态运动中。低浮雕、灰色水泥板框架的建筑体量，最承重的地方是建筑与相邻建筑的接壤处，以及欧文街入口上方处。La Casa是华盛顿特区第一个从平地开始设计和建造的永久支持性住房。私人和公共空间的组合都经过精心安排。
The syncopated rhythm of the exterior cladding blends the fixed form of the urban skyline with the activity of the city street. La Casa is a fixed, reliable presence but it nonetheless absorbed in the life and movement of the surrounding city. In low-relief, the gray cement board frames the building mass, heaviest where the building meets adjacent structures, and over the Irving Street entrance. La Casa is the first facility in Washington DC designed and built from the ground up as permanent supportive housing. The mix of private and public spaces are carefully orchestrated.

要应对高性能墙体组件，以实现业主期望的能源性能水平和视觉设计目标，同时达到成本预算目标，这既是一个挑战也是一个机遇。外部设计的目的是创造一个活力的立面来掩饰建筑的静态结构。在不允许立柱的垂直线伸到外部的情况下，为每个居住单元平均分配玻璃面积是一项挑战。我们使用了柔和的千思板（Trespa）和轻质混凝土板的梯度变化来掩盖结构，同时创造建筑周围的动态运动。建筑面以内的活动旨在反映哥伦比亚高地（Columbia Heights）社区的活力。
Navigating between the high-performance wall assemblies to achieve the client’s desired level of energy performance and visual design goals while hitting a cost budget target presented a challenge and an opportunity. The intent of the exterior design was to create an active façade that disguised the static structure of the building. It was challenging to equally distribute the glazing per living unit while not allowing the vertical lines of the columns to read through to the exterior. We used gradients of warm trespa panels and light concrete board to mask the structure while simultaneously creating movement around the building. The activity within the façade is meant to reflect the vibrant community of Columbia Heights.
邻居的院子提供了一个机会，La Casa可与邻近的市价公寓楼的入口庭院建立动态的视觉关系。我们开发了入口大厅，既可以作为毗邻院子的好邻居，又可以利用便利的设施。
The neighbor’s courtyard presented an opportunity of creating a dynamic visual relationship with the neighboring market-rate apartment building’s entry courtyard. We developed the entry lobby to be both a good neighbor to this adjacent courtyard and take advantage of an amenity.
