Lowtech Graph lists low-tech options for every need of a home. Here you can compare them, find tutorials to build them, and link them together into a circular system. Why low-tech?

Mechanically fastened, non-glued assemblies

Passive · New build only

One of 2 ways to meet this need. Cost, carbon, footprint and rankings are relative to other solutions for the same need, not absolute.

Building with bolts and screws instead of glue, so parts are held together mechanically. Anything can be taken apart again. Parts can be repaired, replaced or reused, and materials separated when the building is changed or taken down.

Limitations of this page

We don’t list sizing or quantities, as the yield of each technique depends on the quality of its build. The catalogue compares options but doesn’t dimension them. Regulatory notes are indicative, with a French example, and need to be confirmed locally.
