High-rise flat? (7)
I believe the answer is:
plateau
This could be a double definition.
'high-rise' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'flat?' is the second definition.

Can you help me to learn more?
(Other definitions for plateau that I've seen before include "Area of livel high ground" , "one has no inclination" , "Elevated flatland" , "Area of flat, high ground" , "Levelling off" .)
