Sun-dried brick (5)
I believe the answer is:
adobe
'sun-dried brick' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for adobe that I've seen before include "Sun-dried brick clay" , "Mexican mud and straw brick, and the hut made of it" , "Clay used for sun-dried bricks" , "Clay for mud bricks" , "house" .)
