天通苑的变身 Tiantong Yuan
天通苑，世界第一大睡城，超70万人口居住于此。因功能设施不完善，这些居民每天往返于天通苑与北京城区之间，导致大量的交通堵塞与环境污染；缺少办公空间带来的职住比失衡，成为天通苑显著的城市问题。
Tiantong Yuan is the home for over 700 thousand people who make the hours-long commute back and forth to Beijing each day. The large concentration of residential only developments in Tiantong Yuan results in massive daily traffic jams on the way to downtown Beijing. During working hours, Tiantongyuan becomes a ghost town.

2018年北京市启动回天计划，系统性改善回天地区公共服务和基础设施问题。将闲置住宅楼改造为办公楼，以增加办公机会，是回天计划在天通苑片区的一项创新性整合示范。
The Home Office Tower is the first project of this type in the Tiantong Science and Technology Park. It is a target area for the city-wide Huitian Plan, which aims to provide a greater mixture of uses in this residential area though converting vacant residential buildings in to office buildings.

建筑调整 Re-arrangement
原住宅楼一层10户，中心走道，设三部电梯，两部剪刀梯疏散。
改造后，利用住宅户内原有施工孔洞，打出一圈环形通道，解决办公疏散问题。将原有中心通道改为设备间与公共卫生间，解决办公基础需求问题。同时利用原有住宅上下水孔洞，增加机电消防管井通道，完成基本办公平面调整；也因此，对原有建筑的梁柱进行了局部加固。
The first floor of the original residential building 10 households, the central walkway, set up three elevators, two scissors ladder evacuation.
After the transformation, the original construction holes in the residential household are used to play a ring channel to solve the problem of office evacuation. The original central channel will be changed into equipment room and public toilet to solve the basic needs of office. At the same time, use the upper and lower water holes of the original residence, increase the passage of the electromechanical fire pipe well, complete the basic office plan adjustment; Therefore, the beams and columns of the original building were partially reinforced.

激发开放城市 Stimulate the open city
为了将原住宅楼改造为办公楼这种具有公共特性的建筑，一方面我们在内部增设多种公共功能空间：南北出入口处增设大厅、咖啡厅与超市；一层增设多个共享办公区与会议室；并在地下室增设健身房、食堂、直播间等。
Additional spaces were added on the ground floor and basement levels such as shared office areas and meeting rooms. And a cafeteria, gym, market, and cafe provide much needed amenities for the surrounding community.

另一方面，我们在楼体外围增设一圈各具特点的橙色外挂公共空间，它们都以橙色铝制的交叉穿孔格栅覆盖，围合出大台阶、室外活动广场、休息区，景观等基础公共空间设施，以对应未来周边使用群体不同的需求。同时考虑到充足的夜晚照明需求，我们在顶部铝格栅内嵌入灯带，激发出更多的城市活动可能。
楼体橙色的不同外挂，如同一个标识，展示着这种改变社区环境的尝试。
The landscaping around the office building is designed as public space for office workers as well as local residents. Orange colored building elements and landscaping provide shade and public seating areas for rest as well as public gatherings. Lighting is incorporated into these additions to extend the period of use for these spaces into the evening. The orange additional also serve to distinguish it from surrounding residential towers and broadcast conversion from a distance.

自此，天通苑人有了一个步行可达的工作园区，上班前有时间与家人共进早餐，下班后拥有健身与电影的闲暇。
这一项目促使天通苑成为职住平衡的社区，证明健康城市开发模式对社会的改变。
