Circular architecture via deconstruction
ArchDaily covered a shift toward circular architecture that uses deconstruction and material reuse—exemplified by projects like Arquivo—as a practical approach to reducing embodied carbon in commercial work. The reporting frames deconstruction not just as salvage but as a deliberate procurement and design strategy for low‑carbon buildings. (x.com)
A lot of “green building” still starts with a wrecking ball, a dumpster, and a fresh order of concrete and steel. ArchDaily’s new piece argues that a lower-carbon version of commercial architecture starts earlier: at the moment a building is taken apart, not after the debris leaves the site. (archdaily.com) The key switch is from demolition to deconstruction. Demolition turns a building into mixed rubble fast, while deconstruction removes doors, floors, windows, counters, and structural pieces in a way that keeps them usable for the next project. (archdaily.com) That changes what architects are buying. Instead of treating salvaged material like a lucky flea-market find, firms are starting to treat old buildings like warehouses full of already-made parts with known sizes, finishes, and quantities. (archdaily.com) The carbon logic is simple: a big share of a building’s emissions happens before anyone turns on the lights. ArchDaily notes that almost 40% of global carbon emissions come from buildings, and a growing share comes from embodied carbon locked into materials such as concrete, steel, glass, and insulation before occupancy begins. (archdaily.com) Once you see embodied carbon that way, smashing usable material starts to look like throwing away a finished meal so you can buy raw groceries again. ArchDaily’s earlier reporting says reused construction materials can have impacts 2 to 12 times lower than equivalent new products for the same purpose. (archdaily.com) The Arquivo story puts a real company inside that idea. Arquivo, founded in Salvador, Brazil, in late 2020, was built to sit between disposal and new construction and to make reuse a service, not just a slogan. (archdaily.com) Its founders, Fernanda Veiga, Natália Lessa, and Pedro Alban, first tested the model through Coletivo Mouraria 53 in Salvador, where renovation work turned into a live experiment in collecting donated doors, countertops, and flooring from a local network. (archdaily.com) They then used the disassembly of the Brazil-United States Cultural Association, known as ACBEU, as a working lab for timing, methods, and on-site sales. ArchDaily says the same consignment model later continued in high-end house disassemblies in Salvador’s Horto Florestal neighborhood, where redevelopment pressure is high. (archdaily.com) That is why this is drifting from niche craft into procurement strategy. If architects can line up deconstruction crews, storage, catalogs, resale channels, and future buyers before teardown starts, reused material becomes part of the specification sheet instead of a last-minute compromise. (archdaily.com) ArchDaily ties that shift to a broader market change. As emissions targets tighten and virgin materials get costlier and less predictable, firms are beginning to build material banks, negotiate deconstruction protocols, and treat cities as “urban mines” full of recoverable components. (archdaily.com) The deeper challenge is that most buildings are still designed like sealed packages. ArchDaily’s reporting on circular construction says facades and assemblies often make later disassembly hard, so the next step is designing joints, layers, and connections so parts can come back apart without being ruined. (archdaily.com) So the story here is not “salvage is back.” It is that some architects now want the end of one building to function as the supply chain for the next one, with deconstruction, resale, and reuse planned as deliberately as structure, budget, and schedule.
