Tree House in Lian Huadang

Location: Dingshu town, Yixing city

Floor area: 104.64 square meters

The Voronoi diagram is used in the skin design of this project to simulate the shape of branch growth. On the one hand, the position of each point in the point set of Voronoi diagram in the field will affect its movement mode and the size of the holes in the corresponding position, so that the skin presents the appearance of density. On the other hand, Dijkstra algorithm is used in the design to calculate multiple shortest paths with distinct primary and secondary orders, corresponding to the “trunk” and “secondary trunk” in branch growth. Finally, a complex digital skin is generated under the control of multiple parameters.

This project is responsible by the architect from the design to the construction, including the detail structure design and component processing, it is a convictive presentation of the digital idea from the design through to the construction.

本项目的表皮设计使用了voronoi图来模仿树枝生长的形态，一方面，生成voronoi图的点集中每一个点在场地中所处的位置会影响到它的运动方式以及对应位置的开孔大小，使得表皮呈现出疏密有致的外观；另一方面，在设计中使用了Dijkstra算法计算出主次分明的多条最短路径，对应树枝生长中的“主干”和“次干”。最终在多种参数的控制下，生成复杂的数字化表皮。

本项目由建筑师从设计到建造全程负责，包括细部构造的设计与构件加工，是数字化的思想从设计贯穿到施工的有力呈现。
