Cupolas

These diminutive structures sit atop a roof ridge and bring light and air into a dark attic space. Check out a few cupolas that also bring style and interest to their top spots.

Light & Airy

Cupolas were originally designed to add natural light and ventilation to the area under a roof. They sit on the ridge of a roof and can be found in many shapes, including square, round, and octagonal.

On barns, they're meant to allow a continuous flow of air into the hayloft, helping to dry the hay. This multi-sided octagon features wooden louvers to promote ventilation.

Tall & Handsome

Glass panes on a square-based cupola allow light into the interior space. Operable windows bring in ventilation.

Making a Point

A square wooden cupola with louvered sides has a spire-like finial, mimicking the gable wall below.

View Too

When a cupola is big enough for a person to look out through its windows, it is also called a belvedere, as in this square cupola in a style typical of Italianate houses.
