A subdevelopment is a small community of houses, often built in a planned way.
Subdevelopments are usually seen as new and modern, but some people think they are not as nice as older neighborhoods.
Examples:
The subdevelopment has many new houses.
I live in a subdevelopment with my family.
The people in the subdevelopment are all very friendly.
The subdevelopment is a nice place to live.
