Materials matter.
The right material is not simply the one with the best story. It is the one that makes sense for the building, the site, the climate, the people doing the work, and the goals of the project.
Choose materials for the whole project.
Natural and alternative materials can offer meaningful advantages, but every material comes with its own properties, limitations, detailing requirements, labor considerations, and code questions.
Start with what the building needs.
Material selection works best when it begins with the requirements of the project rather than with a material chosen in isolation.
Performance
How does the material respond to moisture, heat, cold, fire, structure, durability, and the conditions of the site?
Availability
Can the material actually be sourced, transported, stored, and supplied consistently for the project?
Labor
Who knows how to work with it, what training is needed, and how does the construction process affect the budget?
Different materials solve different problems.
Explore materials by their role in the building rather than treating every material as a competing alternative.
Earthen Materials
Explore earth-based approaches and how they can be incorporated into complete building systems.
Explore systems →Fiber-Based Materials
Consider plant-based and fiber materials in relation to insulation, enclosure, moisture, and construction.
Explore systems →Wood & Timber
Understand how wood-based structural and enclosure approaches fit into natural building projects.
Explore systems →Mineral Materials
Explore mineral-based materials and their roles in structure, enclosure, finish, and durability.
Explore systems →Is this material right for this project?
A material can be technically appropriate and still be the wrong choice for a particular project.
Look at the material in context: the building system, site conditions, available labor, regulations, budget, maintenance, and the people who will use the building.
A material is only one part of the decision.
Once you understand the material, place it back into the larger project pathway.
Start with the building. Then choose the material.
Use the NBA pathway to connect materials to project type, building system, requirements, and the people who make the project possible.
