Habitation module
From Kerbal Space Program Wiki
A habitation module or crew cabin is a part which can hold several kerbonauts but is not itself a command module and thus passive. They can be used in space stations and landers to hold the kerbles.
The habitation module can hold 4 kerbals inside it, making it ideal for creating space stations. Since a space station doesn't need to hold more than 7 kerbals (most of the time) this is the only part that doesn't store too small amount of kerbals or overshoot the amount of kerbals stored.
