Circularity & Design for Disassembly

Why it matters

Demolition is the confession at the end of conventional construction: everything so inseparably glued, poured, and composited that the only exit is the landfill. Construction and demolition are the largest single waste stream: in the EU, over a third of all waste generated (per Eurostat). Design for disassembly writes a different ending before the beginning: connections that unbolt, materials that separate clean, components that carry their reuse in their design. The deeper shift is temporal: instead of a permanent object, a building becomes a decades-long pause in the journey of its materials, after which every beam, panel, and pile is somebody's next building. The same reversible joints that let a building come apart at the end also let it be repaired, extended, or reconfigured during its life. A bolted connection can be opened to swap a failed component or add a room; a glued or poured one cannot.

Role in 001's holistic picture

Circularity is the output half of the loop whose intake is Local & Reclaimed Materials: one half designs how materials leave, and the other meets them as they arrive. Its natural media are timber (bolts instead of glue) and screw piles (the foundation that reverses out — where circularity usually dies first). Circular waste applies the same ethic to daily streams, LCA counts the winnings, and Regenerative Architecture claims them. A building that unbuilds cleanly is "die like a tree" turned into engineering.

In the world

Nowhere is this sense rooted deeper than in Japan, where disassembly is not an innovation but a millennium-old culture. Traditional kigumi carpentry assembles timber buildings without nails or glue — interlocking joints alone, holding the structure and honestly letting it go. The most famous proof has been running for over thirteen centuries. The main sanctuary of Ise is rebuilt every twenty years, a practice counted from 690 CE, and 2013 saw the 63rd rebuilding. The dismantled timber lives on: the great pillars become torii gates or travel to shrines across the country, while the craft passes live through carpenters' hands each generation. Modern Japan turned the culture into law. The 2000 Construction Material Recycling Act mandates on-site sorting of demolition and the recycling of concrete, asphalt, and wood. And even when the Nakagin Capsule Tower came down in 2022 — the Metabolist icon whose capsules were designed replaceable from the start — more than twenty capsules were saved and restored. They dispersed to museums and projects worldwide: dismantling as a second life, not an end.

The idea that a building's parts should outlive the building is already operating as infrastructure too. When architect Thomas Rau needed a town hall for Brummen in the Netherlands built to a fixed twenty-year service life, the answer was a structure designed to come apart. Prefabricated timber elements went up Lego-fashion, and roughly 90% of the materials can be dismantled and reused afterwards. Per the Ellen MacArthur Foundation, the town hall also carries the world's first materials passport — the document that turns a building into a depot of parts for whatever comes next.

That single passport has since grown into a shared registry. The Madaster platform runs across seven European countries and holds material passports for roughly 20 million m² of floor area. Some 18,000 buildings were added in 2024 alone. The registry lets a building's components be located, valued, and recovered when it comes down, so they go to new work instead of the landfill.

How 001 engages with it

House 001 states design-for-disassembly among its founding goals and builds the argument physically. A modular box of timber panels and mechanical connections sits on a light steel frame, standing on screw piles that can reverse out of the ground and leave meadow. The whole structure demonstrates that "removable" and "permanent-feeling home" are compatible. The same preference shaped the build method itself: dry processes wherever possible, chosen partly so the materials stay recoverable. The steel frame, like most of what the house is made of, can serve again. Our manifesto anchors the intake side: circularity begins with what's already available. The Hlibivka design extends that ethic to a whole complex of modules conceived as recomposable elements. The honest gap: no 001 building has yet completed the full circle, disassembled and reborn for real. That is the ultimate validation this sense awaits by nature.

Maturity: applied. Designed-in and built at House 001. The full-circle proof is, by definition, decades away, and documented for whoever performs it.
