build a cloak

[emily wong]

Hello,

It is in today's yahoo news. The article on invisibility cloak says

"Imagine an invisibility cloak that works just like the one Harry Potter inherited from his father. Researchers in England and the United States think they know how to do that. They are laying out the blueprint and calling for help in developing the exotic materials needed to build a cloak."

Why does the article use the word "build", which seems fits only with "houses"? If there is a synonymous word to "build", what it should be?

Thanks!

Emily
