About Unbuilt Exchange

Unbuilt Exchange is an open re-use marketplace where Designers, Builders, Property Owners, and Dealers can post listings for leftover, surplus, and salvage goods. Listing is free, and buyers and sellers can contact each other directly to negotiate prices and coordinate logistics.

While broad platforms like Facebook Marketplace offer similar tools, Unbuilt Exchange is built specifically for the construction community—attracting serious buyers and sellers and keeping the focus on usable, high-quality materials.

Unbuilt Exchange is operated by Unbuilt, an online store where the world's top construction pros, dealers, and manufacturers consign their excess goods. Unbuilt offers pickup and warehousing for select high-value items, ensuring quality inspection and fast shipping while saving sellers time and space.

We also work with dealer partners to offer outlet and open-box products that can be purchased and shipped directly.

Construction is one of the world's biggest challenges for both the economy and the environment. Unbuilt Exchange brings together reusable goods from construction professionals, manufacturers, and non-profit salvage organizations—all in one place—supported by tools and services that make these materials easy to list, find, and buy.

Every sale lowers costs for the buyer (averaging 42% savings compared to retail) and keeps high-quality materials out of landfills, saving over 100 pounds of natural resources per transaction. By helping the construction industry shift toward circular practices, we're reducing cost, waste, and environmental impact on an enormous scale.

Unbuilt Exchange accepts listings for high-quality surplus, salvage, and pre-owned building materials, supplies, and products, as well as appliances, larger furniture pieces, and décor. To maintain relevance for the construction community, we apply light listing guidelines to ensure that posted items provide real value to designers, builders, and property owners.
