架构师提供的文本描述。该项目位于北京清平胡同的主楼，当地被称为“大杂院”，意思是“几栋房子共用的大杂乱的庭院”。房主的父母都住在这所房子里，患有阿尔茨海默病，他们的母亲被困在轮椅上。这意味着保留中国传统的四合院，探索年轻人和老年人共同居住的概念，设计一个舒适的住宅，所有这些都在有限的居住空间内是主要的目标。该项目回答了中国在适应日益老龄化的人口方面存在的问题。

Text description provided by the architects. The project is situated at the main house in Qingping Hutong, Beijing; known locally as a da-za-yuan, which translates as "big messy courtyard shared by several houses". The owner’s parents both live in the property, suffer from Alzheimer disease, which their mother being wheelchair bound. This meant that keeping the traditional Chinese courtyard house, exploring the concept of co-living between the young and elderly, and designing a comfortable home, all within a limited living space was the main objective. The project answers the questions which China has in accommodating an increasingly aging population.

该计划是在基础上建造一个额外的钢屋顶，同时保留胡同原有的木结构-新的钢结构允许二楼，从而扩大了居住空间。建筑师们解决了传统胡同中常见的照明条件差的问题，增加了立面窗户的尺寸，将百叶窗纳入楼梯，并在厨房中安装了一个有趣的圆形天空灯。这些设计特点不仅增加了新家的特点，而且允许光从各个角度注入室内空间。

The plan was to construct an additional steel roof at the base whilst keeping the hutongs original wooden structure - with the new steel structure expanding the living space by allowing for a second floor. The architects resolved common poor lighting conditions found in traditional hutongs by increasing the size of the windows on the facade, incorporating louvers into staircases, and implementing a playful circular sky light into the kitchen. These design features not only add character to the new home, but allows for light to pour into the interior spaces from all angles.
