- Who sells on Unbuilt?
- Builders, interior designers, architects, showrooms, dealers and homeowners with leftover project material, alongside brand partners such as Kohler, Ann Sacks, Cosentino and Concrete Collaborative selling outlet and discontinued stock.
- How is Unbuilt different from a salvage yard?
- Unbuilt is national rather than local, and most of the catalog is unused or lightly used designer-grade material rather than demolition salvage. Every listing states its condition, and items sold by Unbuilt are verified and returnable within 30 days.
- Why does buying secondhand building material matter?
- Construction is the largest source of solid landfill waste in the United States, and roughly half of global resource extraction goes to the built environment. Reusing existing material avoids new extraction and manufacturing entirely.
