Materials

Natural Building Alliance

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.

Understanding Materials

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.

Before You Choose

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.

01

Performance

How does the material respond to moisture, heat, cold, fire, structure, durability, and the conditions of the site?

02

Availability

Can the material actually be sourced, transported, stored, and supplied consistently for the project?

03

Labor

Who knows how to work with it, what training is needed, and how does the construction process affect the budget?

Material Categories

Different materials solve different problems.

Explore materials by their role in the building rather than treating every material as a competing alternative.

The Real Question

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.

01 Where will it be used?
02 What does it need to do?
03 How will it be installed?
04 Who can build with it?
05 What requirements apply?
Keep Moving

A material is only one part of the decision.

Once you understand the material, place it back into the larger project pathway.

Natural Building Alliance

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.
