Forking Nature
Discover the innovative integration of tree forks in contemporary architectural design, promoting sustainability and eco-friendly construction. This project showcases the use of natural geometries and renewable materials to create strong, aesthetically pleasing structures.
Project Overview
The project demonstrates the process of incorporating tree forks into building designs, from sourcing and preparing the materials to advanced computational design and fabrication techniques. This approach not only highlights the beauty of natural forms but also underscores the importance of sustainable practices in modern architecture.

The Process
Sourcing Tree Forks: Local forests and gardens around Detmold, Germany, provided naturally occurring tree forks, which were carefully selected for their unique shapes and structural potential.
Preparation: The tree forks were dried, scanned, and cataloged to create a comprehensive database for digital design.
Design and Fabrication: Using advanced software like Rhino and Grasshopper, the natural forms were integrated into architectural elements, combining traditional woodworking techniques with modern digital tools.
