.build domains

The .build domain is an extension aimed at the construction and creation industries, from builders, architects, and contractors to software developers and makers who ship products. The word covers both meanings of building, physical and digital, so it suits a construction firm's project site and a developer's build tools alike. A name plus .build states the work directly and forms a clean, descriptive address that is easy to remember and advertise. Registration is open to anyone worldwide and follows standard one-year terms. Because the extension names an activity rather than a niche noun, it is flexible enough for trades, agencies, and technology teams, while still being specific enough to signal purpose. For a company or individual whose business is about making things, ending the address in .build puts that identity into the domain and reads as a statement of what they do.
