hey here in egypt we have what we call house teams ( nurses and workers) who go to homes for vaccination against polio for example is that what you mean or not?

In America, more people work from their house. Some working as a group to complete special job assignment, so call "House team". Xue-ping

Some high schools in Britain and Australia are divided into Houses [ like in Harry Potter] named after famous people or colours. A teacher is responsible for students from year 7- 12 in each House giving them advice and dealing with discipline issues. Students compete for points during sports days. Example: Red House came first in Athletics, but Blue House came first in the Swimming Carnival.

Maybe you mean "home team." That's like, when there's a sport, and it takes place at your teams school or field. You're the home team. Just saying.
