What Are Cupolas?
Cupolas are basically the dome like structures present on the top side of a building. These are generally used to provide a unique look to the roof top area or to shun away the boring constructional element. It would not be a wrong thing to say that a cupola is just like a dome or crown present on the roof area.
Window cupolas are also in great trend these days as this make a simple looking balcony area of your home or office look simply classy and architectural rich. Some other variations of these cupolas are hexagonal, octagon and louver ones.
