An attic

Louver (PSF)

The attic is the highest part of a house, it is directly below the roof and old house or old things inside the house like a vintage. It is sometimes used as storage. Some people have "loft conversions" (change the attic into a room people can use) so that they can sleep in it. Attics can be hard to reach, which is why many of them are not used. They can help keep the temperature of the house stable.
