OK, clear enough. But that's an unusual definition of "build" that I don't think you should necessarily expect others to share.

The first entry for "build" in the OED is: To construct, put up, erect (a house or other dwelling or building); to construct (a permanent static structure such as a wall, bridge, or architectural feature, a road or railway, etc.). Also: to commission, finance, direct, or oversee the construction of (something of this type).
