It's built with sound glue at the medical centre (5)
I believe the answer is:
igloo
'centre' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for igloo that I've seen before include "series of chilly blocks" , "Arctic dwelling" , "basic dwelling" , "packed house" , "Icy home for Eskimo" .)
