- What can you buy on Unbuilt?
- Building materials, tile and stone, lighting, kitchen and bath fixtures, doors and windows, appliances, and décor. Inventory is a mix of unused overstock, showroom and display models, open-box returns, and reclaimed architectural salvage.
- 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?
- US construction generates 10 pounds of debris per American, every day — twice what each of us puts in the trash — and half of everything humanity digs out of the earth goes into buildings. Reusing existing material avoids new extraction and manufacturing entirely.
