The developers, a couple with careers in the media, were not satisfied with the double-pitched roof originally specified by the building authorities, and so they looked for a more interesting alternative.
In trips abroad, the couple was particularly impressed by large barns in Ohio with their highly rounded roofs.
Starting at eaves which are vertical like a façade, the roof curves protectively over the top floor and then runs at an approximately 30 degree angle to the ridge.The half-offset roof tiles emphasise the horizontal lines.In Scandinavia, they were struck by the contrast between the dark roofs and light wooden façades.These two impressions gradually gave birth to an idea of a house with a large, convex tiled roof.The flat, true graphite Koramic Actua 10 roof tiles represent the dark hull of ship.
In addition, notes Minckwitz, “roof tiles are a modern phenomenon and hence give the traditional roof shape which initially arose in the 1920s a new, modern twist.” The roof is covered with tiles from stem to stern and takes up approximately one-third of the height of the building.
Even though the roof is covered with flat roof tiles, the curve seems natural.
The special, straight Actua ridge is an appropriate choice for the design.
In contrast to a genuine barrel roof that does not have a slope or a ridge at the highest point of the roof, the zeppelin roof has a slope and a ridge at the top which allows it to be completely covered with roof tiles.
This particular round roof design first came into being around 1920 and is characterized by the so-called Zollinger style.
