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.

Since 1968, Topsider Homes has been designing, pre-engineering and prefabricating octagon houses.  With thousands of octagonal homes shipped worldwide, no prefab, pre-engineered or kit house company has Topsider’s experience or expertise in octagon home building.

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.

Topsider's multi-sided octagon prefab homes are extremely flexible in design and easier to build that round houses or traditional 'stick built' homes.

This multi-octagon home fits snugly into the terrain as if it grew out of the mountainside. Topsider octagon pedestal homes are efficient to build, and don't require massive excavation.

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.

Building Elevated Homes & Raised House Plan Designs by Topsider Homes

Topsider Homes has been the leader in elevated homes and raised house plan designs since 1968.

The first Topsider Home ever built (circa 1968) in Banner Elk, NC. This unique pedestal house design elevated the living space above the trees for great views, and required only limited excavation – unlike traditional foundations. Since 1968 thousands of Topsider pedestal homes have been built throughout the world.


Topsider Homes’ high-quality pre-engineered prefab post and beam building approach makes elevated homebuilding easy.  Unlike traditional prefab or stick built homes, Topsider Homes’ basic structure was designed to be elevated.  It is not a ground-level type house design adapted to be raised or elevated. That’s why Topsider’s post and beam structural skeleton is far superior to other building systems and design approaches – and why it is also naturally hurricane-proof and earthquake-resistant.

The earliest Topsider Homes were pedestal home designs built in the late-1960s and constructed on steep, sloping mountain terrain where traditional foundations would have been unsightly, expensive and destructive to the surrounding natural environment. These early green-built homes were very unique and allowed for homebuilding in locations that would be otherwise unbuildable.

While many of today’s Topsider pedestal homes continue to be built on severely sloping terrain, many are also built in coastal areas where elevated houses are a necessity to protect against floods, hurricanes and tropical storm surges.  In some locations Topsider Homes have been built to heights in excess of 20 feet above ground level.

As the leader in elevated home design, Topsider offers a variety of foundation options. These include stilt (piling) homes and other raised house foundations including crawl-spaces, short concrete piers, etc.  Taller houses are typically built on stilts (pilings) of wood, concrete or steel.  In some flood-prone locations, the ground level around the stilts or pilings can be enclosed with breakaway walls or walls with flood vents that will not impede the free flow of water. These ground level enclosures are frequently used as garages and storage spaces.

Elevated homes are typically built to accommodate sloping or uneven terrain, to provide safety from floods and storm surge and to enjoy the best view of the natural surroundings.  In very remote wilderness locations, some Topsider clients have built elevated houses for security from bears and other wild animals, and to be above the deep snow pack in high mountain ranges.  We have even designed remote-controlled folding stairways like draw bridges for added home security when the owners are away.

Save Up To 35% Import Duty in Exuma (Bahamas) If You Build Your New Topsider Home by Mid-2019!


Exuma is now Import Duty exempt, but only until June 30, 2019!  Previously, under the Family Island Development Encouragement Act, a handful of Bahamian Islands, including Long Island, Cat Island, Andros, Rum Cay, San Salvador, Crooked Island and others (click HERE to see complete list) were the only islands exempt from duty on building materials – also ending mid-year 2019.


If you are considering building on Great Exuma or Little Exuma – or on any of the other duty exempt islands, there has never been a better time or reason to get your homebuilding project underway.  With a limited number of reliable builders available on these islands, many are already booking projects into 2019. Builder availability will become an issue as 2019 approaches – so time is of the essence if you wish to beat the deadline and save up to 35%!

Topsider Homes has been building in the Bahamas for 50 years.  Because we understand the Bahamas and the challenges there, we have developed a unique and comprehensive approach and package of services for our clients.  It begins with FREE Cost Estimates for any of our more than 250 online house design concepts, so that prospective clients have a starting point from which to work for design and budgetary consideration.  These estimates include the cost of Topsider’s delivered house package plus a detailed breakdown of estimated local construction costs.

Once clients are comfortable with a preliminary design and budget, we begin the “design phase” during which we develop house plans and detailed building specifications. This is followed by construction documents (blueprints), engineering and other technical data and details needed for builder bids, building permits and so on. This is all handled in-house by our design and technical staffs.  Also during the design phase, we recruit and pre-qualify builders to bid on projects – a process we oversee and coordinate.  We have many experienced builders in the Bahamas, but we regularly recruit new ones so that clients have a good selection.

Once all the plans and builder bids are in and the costs tied down (including items such as water-catchment, septic, power to the building site, etc.) clients then engage us to fabricate the pre-engineered house components in our factory for shipment.  But our services don’t stop at our door, we take the technical lead for building permits and approvals, arrange all logistics and coordinate the ongoing project with the local builder until it is complete.

We understand building in the Bahamas. Our homes are designed to be low-maintenance, hurricane-resistant and efficient to build by local contractors. All of this ensures a higher level of cost control and quality than the typical “stick built” construction approach.  Topsider offers a comprehensive package from design and materials to project coordination, but all of these important elements and steps take time. With the June 30, 2019, deadline looming on the horizon, now is the time to get in touch with us and begin the preliminary steps to get the ball rolling!
