Mechanically fastened, non-glued assemblies

Bolted/screwed rather than adhesive-bonded construction, so components can be separated at end of life.

Cost

Low

Upkeep

None

Skill to build

Basic

Lifespan

Not applicable, a fastening-method choice; individual assemblies follow their own material's lifespan

Embodied carbon

Low

Space / material use

None

Output timing

None

Skill to repair

Basic

Note: Cost, carbon and footprint are rated against the other options for this same need, not in absolute terms.

What this page does not tell you

No sizing or quantities: how much a technique yields, and how much a household needs, both depend on the build and the people, so the catalogue compares options rather than dimensioning them. It carries no bill of materials and no build sequence, and it is written for an oceanic, clay-soil climate (Normandy, France). Regulatory notes are indicative and need confirming locally.
