Stayed in central, extremely sustainable, terraced-houses (8)

I believe the answer is:
remained
'stayed' is the definition.
('remain' can be a synonym of 'stay')
'central extremely sustainable terraced-houses' is the wordplay.
I cannot really see how this works, but
'central' could be 'main' (I've seen this in another clue) and 'main' is found in the answer.
The remaining letters 'reed' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for remained that I've seen before include "Was left" , "didn't move" , "Stayed put as I meander" , "Stayed behind" .)
