I came across a Texas specialty builder in my backyard that I wanted to bring to your attention. It's called Monolithic Dome Institute out of Italy, TX. They make dome shaped buildings and homes and this is a little bit about what I learned about them.
The construction costs are similar to custom homes and a little higher than tract homes. They give you about 75% savings on the energy costs which translates to about 50% savings on the bill. They have even in the Pensacola area been known to survive a direct hit from Hurricane Ivan. They have good insulation across the roof with a composite of rebar and concrete laid on it.
My question for many, is I wonder how the resale is on these, because while they have many advantages, they are VERY different! I wonder.

It's very niche-centric, but I personally love it.
Jill: I had seen this design a number of years ago at the State Fair and knew one of these homes built out in the country. By being such a niche that's why I wondered how hard it might be to sell one day.
Audrey: You would be the only one in the neighborhood with this architecture.
Kathry and Carole: The web site does show the interior which looks normal other than the curved roof.
Linda: It probably would take some getting used to.
Gary,
That is so weird! I was just looking at this type of property near me! Check out this link: http://www.bigbeardomehome.com/html/bigbear.htm

Rich: Great video on the subject. More than you would imagine. Especially protection against fire.
Karen: That's the ticket. Put the domes in a golf community. Very clever.
Joan: That is my theory too.
Rosario: I like you phrased it that the "majority" have more conventional ideas.
I think it's cool - very futureistic looking! I'm more of a traditional girl myself but this one gives me the feeling that maybe I should be open minded. Thanks for sharing Gary!
Kim: The insides are quite beautiful. You just have to get used to the curved ceiling.
Patricia: Now Christmas lights, that would certainly look different.
Carol: We get stuck in our conventional thoughts don't we? Eskimos might think these resemble igloos.
Marchel: Re-sale problems is what I heard too. Kind of cool for buyer #1, but how hard is it to find buyer #2? I agree that most HOA's would think you were a radical if this is what you planned on the lot you purchased.
What could an appraiser compare it too? I am assuming there is nothing else like it in the area and even if there was, how often do they sell? I think this would have to be a specialty property and pretty much cash only.
Chuck: On the web site they showed some example interiors which looked pretty good.
Todd: Appraisal could be tough with a one of a kind property.
Gary,
Saw your post over on Terry Westbrook's blog, and just had to come see for myself! This is pretty unique!

Mike: The dome house is quite different I admit.
Scott: The protection from high winds is one of its great strengths.
We own one in Wisconsin and it is amazing! Very low heat bills and we added huge windows that give a panoramic view of a Class A trout stream. It's built into a hillside so is like living in the trees. One of a kind, yes, but just gorgeous. We rent it out and live in Virginia, but hope to return some day.
