Building … or a building material, if you swap its consonants

ABODE

Think of a simple word for "home," then consider how rearranging just two letters inside it could turn it into something used to make walls.

The answer "ABODE" fits because it means a building (like a house). If you swap the consonants in "ABODE" (B and D), you get "AODE," which sounds like "adobe"—a common building material made from clay. The clue plays on the double meaning of the word while hinting at the letter swap.
