To form the concept of so-called "cities," human habits should not be completely separated from the natural environment. This project proposes a new approach to the division of human living space: to find a new way of dividing space that is dynamic and responsive to the natural environment, starting with the optimal human-nature relationship.
Space is not designed, it's found.
- This project proposes a new approach to human living space planning.
“Architecture is never fixed. It is always affected by the environment, time, or people. So, I want to make new types of flexibilities in such a way that my architecture can be redefined and used differently. I want my architecture to be loose, so there are many interpretations.”

Dynamic house is a dynamic building robot that adapts itself to the ambient temperature. The pneumatic skeleton is driven by an outdoor temperature sensor to change the size of the pores in the knitted fabric on the surface and regulate the room temperature.
1. Project Workflow
2. Project Background
The traditional space in which people live nowadays has always been static and artificially divided, but the space in nature is always dynamic. Human beings are born in nature and should follow nature, and the habitat of human beings should not be cut off from nature to form the so-called "city".
Traditional urban architecture tends to isolate people from nature. Whether it is the macro urban agglomeration and nature's obvious demarcation line, or indoor and outdoor by the hard "right angle", "white wall" division.
This makes human beings less and less influenced by nature and the outdoors, and it seems that living in the city, with doors and windows closed, nature or the outdoors are no longer relevant to the occupants of the house, and in my opinion, such an isolated and depressing atmosphere does not in fact correspond to the natural needs of human beings.

Single tree analysis
The point cloud data was analyzed using LiDAR360 to obtain the two-dimensional coordinates of each tree.

4. Data Collection: Human Walking Path
Path Restoration
The intersection of the negative space delineated by the tree and the human path from the whole space needs to be separated.
Trees are born as space dividers, and people create paths based on thermal comfort and walking freedom, both of which are examples of nature assisting us in finding space.

Data Processing - Convex Hull
ConvexFromPoints – Compute a convex mesh from a set of points.
The forest point cloud data on the path is computationally analyzed using the convex hull algorithm in grasshopper, which geometrically summarizes the point cloud data into a combination of low surfaces.
5. Model Simplification: “Mondrian Evolution”
The model is continuously simplified by reducing the number of similar vertices until it is reduced to a series of connected tension structures.

6. Model prototyping: Tensile Structure
Substantiation of the final model summarized in grasshopper
Different variants of a standard tensioning structure produced by varying the length of the elastic rope
Robot Motion Principle
A standard tensioned structure consists of two types of triangles：
Isosceles Triangle (1, 2)
Equilateral Triangle (3)
Structural analysis of two types of triangles on the tension structure
7. Robot Structure Design
The robot is designed according to the analysis of the principles of tensioning structures, and there are a total of three structural units on the robot: the main support bar, the bellows that is driven to contraction by an air pump, and the secondary support bar.
Expandable bellows
Pneumatic Device
Making a pneumatic device out of bellows and a small air pump to drive the tensioning structure.
Examining the effect of the air pump pulling the object and establish a relationship between the temperature collected by the temperature sensor and the amount of air pumped.
Pneumatic device dragging object experiment
8. Hardware Development
Temperature sensor data control air pump:
The temperature sensor regulates pumping capacity by collecting ambient temperature data, with pumping capacity decreasing as temperature rises and increasing as temperature falls.

9. Knitted Fabric
Fabric movement mechanism
Fabric edges are classified into two types: shrinkable and fixed length. The fabric's movement mechanism corresponds to the tensioned structure.
Design and manufacturing tools
Fabric development using hand crank knitting machine
Mass production of knitted fabrics on digital knitting machines
Fabric hole area varies according to temperature
Final Demonstration
The ambient temperature decreases, the pneumatic device shrinks, the fabric pore area becomes smaller, and the room temperature increases; and vice versa.
