The terms “cupola” and “dome” are often used interchangeably, leading people to ask, "Are cupola and dome the same thing?" Cupolas and domes are actually two distinct architectural elements with specific features unique to them. While domes can often be seen on large, ornate buildings (such as art museums, government offices and churches) they are not typically suited to residential use. Cupolas, on the other hand, can easily be incorporated into any size home, garage, shed or outbuilding, adding both beauty and function to the structure.
What is the Difference Between a Cupola and a Dome?
Domes are always circular, with a rounded roof that resembles the upper half of a sphere. This design makes them self-supporting, which means domes contain no interior supports, allowing them to create large open areas. Because the main goal of a dome is to provide open space, they do not necessarily add extra light and ventilation. Furthermore, domes can also be difficult to incorporate into existing structures. They work best on flat roofs and cannot be placed on the traditional sloped roofs of residential homes without extensive modifications to the house.
Cupolas were first introduced to architecture back in the 8th century, and their overall design hasn't changed much. They can be round, square, hexagonal or octagonal in shape and are comprised of three parts: the base, the vents and the cap. The "vents" can be louvers, windows or a combination of both, and the "cap" (roof) typically has a distinct shape (such as bell or concave) to help shed rain, snow, leaves and other debris.
The main purposes of a cupola are to increase ventilation, add natural light and improve the aesthetics of a home. They are easy to install on any style roof and require only minimal alterations to your roofline. While cupolas and domes are not the same thing, they can often be seen together, with cupolas gracing the tops of domes to serve as belfries, lanterns or look-outs, the most famous example being the cupola and dome atop the U.S. Capitol building.
