Octagon Houses and Octagonal Home Designs by Topsider Homes

Octagon house designs have been around for thousands of years and were very popular in the mid-1800s in the United States with thousands of homes built in an 8-sided geometric configuration.  In fact, the headquarters of the American Institute of Architects (AIA) in Washington, D.C. is located in a historical building called “The Octagon” that was built in 1801—so the eight-sided design is a well-established architectural style.

Early-era Topsider Homes were all octagonal shaped and built on pedestal foundations.  For this foundation type, the structural characteristics of an 8-sided design were superior and far more efficient to build than square or round house geometry.  That same 8-sided geometry was found to have other benefits for building on stilts, pilings and even on traditional foundations. For example, Topsider stilt homes require only 9 stilts or pilings – one in the middle and one on each of the 8 corners. Square houses and round houses typically require many more, particularly the larger the house size gets.

This octagon home was built on severely sloping terrain in Hawaii using a Topsider pedestal house foundation. This high quality prefab home was easily erected on its challenging site and provides endless panoramic views.

There are many other advantages to Topsider’s octagon house designs and pre-engineered post and beam building system. Topsider’s exterior walls are non-loadbearing and as a standard feature come with floor-to-ceiling windows so that clients can enjoy the panoramic views of their natural surroundings.  Traditional and “stick built” homes, and many prefab kit homes, square and round in design, have exterior walls that support the roof – that limits the number and size of windows.

For home buyers who want a multi-sided house design, the octagon shape has many advantages.  It is much less radical in appearance than hexagon (6-sided) homes, round and circular house designs, dome homes and yurts – and it is less complex and easier to build.  These more extreme geometric shapes and building systems are also more difficult to finance.  And they are typically sold by kit house and prefab home companies who offer only limited, if any, assistance in providing credible construction cost guidance, qualified builders, direct involvement in building permits, and logistical and technical coordination throughout the entire building project.  Topsider Homes’ provides all of these services, plus free custom design, with the purchase of any of our homes.

The History of Octagonal Homes and Structures

Octagonal homes originally became popular throughout the United States during the late 19th century, but their recorded history dates back thousands of years. The octagon shape has always been a symbolic architectural theme representing regeneration, rebirth and renewal. The oldest known octagonal structure is The Tower of the Winds in Athens, Greece which was built in approximately 300 B.C. Over the years the octagon has been used in constructing churches and temples for its many spiritual representations. It was during the 1850s that octagonal homes became a popular architectural style, due to the influence of Orson Squire Fowler’s book The Octagon House: A Home For All, or A New, Cheap, Convenient, and Superior Mode of Building (1848). Fowler’s book portrayed to people that there were numerous advantages to an octagonal house plan. One of the advantages of an octagonal design is that the multi-sided shape encloses space more efficiently than its counterpart, the square; therefore, decreasing heat loss and gain. Additionally, an octagonal structure permits more natural light, aiding in the reduction of electric bills for illumination and heating in the winter and from a livability standpoint, octagonal designs allow for panoramic views and easier orientation on the building site.

In the past few decades octagonal designs have been revamped into more contemporary home designs that utilize Post and Beam building techniques. Expert in this application is Topsider Homes, who designs and manufactures its octagonal structures to custom specifications. Topsider Homes provides a new genre of building designs by marrying their unique pedestal foundation to an octagonal structure using a Post and Beam building system. The combination of these design and construction principles has created homes that are “structural battleships,” able to withstand hurricanes and earthquakes. Topsider’s unique octagonal homes permit 360 degree views making them very popular in vacation and scenic destinations, such as on the beach or the side of a mountain. They adapt to the terrain and climate of almost any building site and can be built on a wide range of foundation types, including pedestals, pilings, basements, slab and crawl-spaces. These octagonal house designs are ideal for residential areas, retirement homes, home additions and more.
