Unique and Unusual Roofs

The “Leaf House,” located on beachfront property just north of Rio de Janeiro, Brazil is a spectacular design inspired by native architecture. The shingled, leaf-shaped roof is intended to not only amaze, but to also counteract the hot and humid climate that Brazil is known for. It covers 8,600 square feet of the home’s enclosed spaces and in-between breezeways.

The traditional homes of the Torajan people of Sulawesi, Indonesia are called Tongkonan. Dominating the impression of the building is the saddleback roof. Bamboo planks bound with rattan are layered and tied lengthwise to the rafters to form the roof. The under roofing consists of the hollow stems of bamboo. The distinctive shape is obtained by creating a series of vertical posts that support beams that are angled upward. A freestanding post supports the portion of the ridge pole which extends beyond the ridge purlin.

In Beaune, France, the Hospices de Beaune is an old charity hospital dating back to 1443. It is a prime example of fifteenth-century French architecture. What makes this building especially unique is its roof, which is decorated with red, brown yellow and green colored tiles applied in an intertwining design. The building’s roof certainly made it a landmark of the architecture of France’s Burgundy region. The hospice eventually became a museum, and the tiles were replaced in the years between 1902 and 1907.

The Sydney Opera House was constructed with gigantic precast “shells” of concrete spanning nearly 250 feet in radius, which form the iconic roof structures. For six years in the mid-20th century, designers went through a dozen proposals on how to form the shells in an effort to find an economically feasible solution. In 1961, the design team finally decided that the shells would be created from sections of an enormous concrete sphere, allowing arches of varying length to be cast in a common mold. The roof shells were then covered with more than a million white- and cream-colored tiles imported from Sweden. Altogether, the building covers 4.4 acres, measuring 600 feet long and nearly 400 feet wide at one point.
