* Homes are individual: Unlike animals or objects that naturally form groups, homes are usually singular entities.
* Neighborhoods and communities: We use these terms to describe groups of homes, but they aren't specifically collective nouns for homes.
Alternatives you can use:
* A cluster of homes
* A row of houses
* A development of homes
* A community of residences
* A collection of dwellings
You could even be creative and use something like "a haven of homes" or "a tapestry of abodes."
It really depends on the context and the specific image you want to convey.
