两代人的小家 & 北京胡同内旧房改造 / CAA希岸联合建筑事务所

该项目位于北京老地标建筑北京站西侧，是四合院里的正房。屋主正值壮年，他的母亲患有阿尔茨海默症并需要使用轮椅。房子曾被改造，原有结构遭到破坏导致房屋出现通风保暖和功能划分混乱等一系列问题。该项目的难点在于如何在保护中国传统四合院结构的前提下提供更多的设计可能性，给迈入老龄化的中国提供良好的住宅示范案例，让一间60平米的小平房同时满足两代人的居住需求，为老房子赋予新的活力和新的居住形式。

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.

屋内加建钢结构用以承重，形式上保留了原有木结构，在最大程度上还原历史。利用原有挑高，隔出二层，增加卧室。结合现代建筑设计元素，为病危老人设计的无障碍设施低调嵌入各处细节。天顶圆窗的形式表达独特的东方审美，呼应四合院的传统形态。

厨房屋顶和外立面铺满绿植，屋顶变身小花园。隐藏在绿植里的楼梯出人意料地从屋里经由窗户延伸至窗外通向屋顶花园，向上扩展的空间打破原有物理空间的禁锢，赋予居住者全新的希望，探索新的居住可能。

由于需要帮助阿尔茨海默症患者留住记忆，本次设计向传统再生回归，融入怀旧元素，突破了以往科技范未来感的设计风格，是CAA在老北京胡同改建与提升人居环境方面的一次全新尝试。

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.

Vibrant plants and greenery flow up from the courtyard floor in a “Z” like manner, and onto the kitchen rooftop that surrounds the skylight. The head of CAA, Liu Haowei describes this feature as “Old Beijing walking in the sky”

The result is a project that follows CAA’s core values; embracing the constrains of unique sites, and elegantly balancing between historic preservation and modern living. The Qingping Hutong House integrates light, openness and contemporary style into a limited space, creating a new hutong lifestyle for all.
