We generally don’t see round houses built by the major home construction companies. Many of us think that only ancient Mongols used to live in strange-looking circular houses called Yurts many centuries ago. Nowadays we don’t even see round circus tents anymore…
It may come as a surprise but round houses are actively continued to be built around us ranging from tiny granny pods to impressive multi-million dollar villas and skyscrapers. There is only a handful of dedicated round home builders yet they are doing an increasing volume of construction year after year. Some of them manufacture small round house kits that you can even assemble yourself while others custom build 3-10 bedroom homes consisting of a few interconnected round modules.
So, why some people choose round house plans over regular ones?
Let’s examine what high-level professionals like World-famous architect Eli Attia write about the cons and pros of building circular houses.
1. The Round form is the most economical in terms of exterior walls vs interior space
The exterior wall surface, in general, is the most expensive part of the building. We all know that exterior walls should protect us well from extreme temperatures and the elements. Saving money on insulation and materials will result in energy waste and high utility bills.
The above drawing illustrates that building a small 900 SQ FT round house will require 14 FT fewer exterior walls than a 900 SQ FT square house. Imagine the difference if the rectangular house plan would consist of several squares and rectangles as most of the modern home plans usually do…
Eli Attia states:
…a round building form is significantly more resource-efficient than any other building form, including the most environmentally sound homes built today.
2. The best hurricane proof houses are round houses
Every year hundreds, sometimes thousands of homes get destroyed by hurricanes. Round homes make much better hurricane-proof houses than traditional square ones. Here are a couple of examples showing round houses built by Deltec Homes in Florida right after hurricane Michel.
Both videos show only a loss of some roof shingles and no other damage. The answer is in streamlined shapes of circular homes – the wind goes around the curved walls without strong resistance.
…the superior aerodynamic behavior of the Round house reduces the wind pressure load acting on the building to its minimum — less than half (!) that of a square building (center) and much less than irregular building forms (right), making the RHT’s round form the most effective, least expensive to withstand high winds. – Eli Attia
3. Earthquake resistant
Small round homes that some people may also call Yurts are often assembled from individual panels that are tightened with a cable near the roof. This is done to avoid putting the post in the middle of the house that supports the roof. This cable system creates a super sturdy structure that can sustain even pretty strong earthquakes.
Larger round homes are often designed as several interconnected round modules. So, instead of one large roof, each module supports just a portion of the roof which is lighter and has fewer chances to collapse during the earthquake. Round home builders like Deltec Homes also use stronger roof ties for attaching roof trusses to walls. The whole house is usually designed to be wind, hurricane, and earthquake-resistant at the same time.
4. Energy efficient
During windy conditions, the air goes around the house penetrating much less through the spaces around windows and doors. Flat walls of regular rectangular homes often work as sails resisting the air going around and letting it in. Thus, circular houses are a lot more energy efficient during cold and hot weather.
In addition, heating or cooling the round house is also easier and faster because the air goes around the curved walls and there are fewer pocket areas where cold or hot air can be trapped.
5. The Round house gets more daylight
More daylight means not only saving on utility bills but also sustaining a healthier environment inside the house. Although we all should be careful about overexposing ourselves to excessive doses of sunlight, it is also proven that ultraviolet UVB rays coming from Sun are also very damaging to bacteria and even the most dangerous viruses (see a recent study).
Ultraviolet (UV) light destroys the molecular bonds that hold together the DNA of viruses and bacteria. UV light is a particularly good option for sanitation because it kills bacteria regardless of drug resistance and without toxic chemicals. – Katie Scarlett Brandt – insider.com
Now, after we established that round homes have many important advantages over the traditional square ones, let’s look at what affordable round house options for budget-minded people do we have here in the US.
There are two US manufacturers that fall into this category: Smiling Woods Yurts and Freedom Yurt Cabins. Don’t let the term “Yurts” confuse you – their products are not round tents made of deer skin. Both companies produce all-wood round cabins with tons of customization options.
For people with a bit more substantial budget in mind, there is another round house builder Deltec Homes that offers a wide range of round house plans from 300 SQ FT to 2,500+ SQ FT.
