FUTURE
SHELTERS

Part I

Welcome to the primitive future. People have slowly started moving to the countryside for extended periods of time. Others are struggling to build their new homes because the global warming has destroyed their old ones. This new lifestyles would require a shelter that is mobile, cheap, diverse and easy to make by inexperienced people. Here is how this will work:

shelter workflow diagram
Workflow from forest to construction is moistly autonomous
centerline generation method
Centreline generation would be carried by the data the user provides
data simplification of branches
Data simplification via topology remapping is necessary to speed up the assembly process
novel spatial shell design
This is one of the novel spatial shell design systems proposed.It can fit random “triangle” branches into dome like structures.

To validate the construction technique proposal, evaluate its properties and appearance and participate in the WG21 Design Competition a real 1:1 pavilion was built. The branches used for the full paper were transformed (trimmed) to fit in the competition requirements – 6 cargo boxes with size 650x750x1000:

bigger branch shelter
The structure can be expanded and can grow vertically by using more branches. If local wood is used, the only thing you need is a phone, a saw and some joint materials.

Paper abstract:
T
he aim of the research is to propose a workflow and an assembly tool for architecture based on curved wood in its whole unmodified form e.g., wasted crown wood from producing sawn timber, wood thinnings cut during forest management or just branches found in the woods. This paper describes the workflow from collecting the real wood to algorithmically generating a shelter structure. The authors propose a new spatial system suited for irregular elements along with a computer tool to generate all possible variations out of the input branch data. The merit of this approach is that it could fit any number of randomly sized branches together into combinatorically predefined structural shell surface, made of irregular triangles. The fitting is based on different parameters such as size, weight, curvature of the branches and can be filtered by the structure’s height, interior volume, plan area, surface area of the shell, etc. The user can control these parameters to select the best solution to be build. This shelter generation method could be deployed to smart devices and used remotely in disaster mitigation and relief after earthquakes, floods or in times of wildfires and other emergency situations. This approach to architecture could prove useful because of its speed and ease of construction, low market price, as well as introducing a new way of shelter design generation.

Pavilion:
Many thanks to IASS organisers for also providing the pavilion presentation video from the conference session. I would like to thank to prof. Mikio Koshihara for supporting me in obtaining the branches for the pavilion, as well as to Tatsuki Yasuda and Firas Hawasly, without which I would not be able to make the pavillion.
