"To build a sandcastle" in Spanish is "edificar un castillo de arena." It literally means "to build a castle of sand." There are a host of English words that are composed of two or more smaller word, e.g., sandcastle, stardust, pigpen, classroom, etc., which are grammatically not done in Spanish. Unlike English, Spanish doesn't [normally] put two nouns together and pretend that one modifies the other; at least to a far, far lesser degree than English does.
