Why have the chimney outside? It's very inefficient... https://www.quora.com/Why-do-American-houses-often-have-the-...

Not to mention wood fireplaces in the home and the noxious byproducts they produce is likely to shorten your lifespan considerably.

Constructing a building that would last 1000 years is not particularly hard with modern engineering and materials. The hard part is, first and foremost, getting someone to pay for it. I'm not going to live 1000 years. My great grandkids likely won't even live to see the year 3022. Why would I spend orders of magnitude more for a house if a structure meant to last ~100 years serves my needs perfectly? My friend just n…

Yeah, unless I' rich and thinking about building my family somewhere, I wouldn't even touch this idea. And even I do, I'll probably purchase an old, but good-standing building and heavily renovate it. Modern technology also provides means to strengthen the foundation and weight-bearing part of the building.

You should still use reinforcement in the concrete: Use basalt rebar instead of steel; it will not corrode. Use a nylon fiber in the mix to protect against impact and spalling from fire. Use 5000 psi concrete instead of 2500. This is much stronger and will be less likely to break down under any environment. Use a vapor barrier underneath to help prevent moisture and gas from coming up into the house. Put the foundati…

It's "steel" here, and "shutters"

Thanks...fixed.

If I were to design a house with the idea that it should serve future generations, I'd design it to be reconfigured, recycled, or torn down easily. After reading some of Stewart Brand's writing, I've learned to love ugly buildings.

I think the reconfigured / recycled easily makes sense. Tough to build a product in 2000s for life in the 2900s. That said the cost to make homes reconfigured/recycled easily is probably quite high and who knows if there will be people with knowledge to be able to perform that work in 400 years. Whereas a shelter can always be used by humans...

I personally believe that you need to find a compromise between a framework that lasts very long and party that can be recycled so you can adopt the house depending on your needs without needing to redo everything (for example foundation and some integral supports could probably be designed as a framework that can be adapted while walls, windows, room configuration, doors, etc. need to be changed eventually and therefore should be recyclable).

>The second problem is making sure people want to maintain the structure for 1000 years, or at least not tear it down. I don't think this is as hard as the other comentors are saying, though. Just don't build the house in a city.

I live in about a 200 year old house but it has been extensively reworked over its lifetime including by me. And given that it's on a nice piece of exurban property it's hardly a stretch to imagine someone in that time deciding a teardown just made more sense than all the upgrades that have taken place over that period. Just as one example it presumably didn't have indoor plumbing when the first part of the house was built.

This is interesting. About to do a major reno on an old home (early 1900s) and definitely had questions about making upgrades that would last a long time. One of the greenest things that you can do to a home is not build a new one as I understand it. Another one would be to build it so it lasts ... not like this throwaway society we live in. That said I don't think I can do steel girders to extend the life of the hou…

Look into Passive House designs, and videos by Joseph Lstiburek if you are interested in energy efficiency and building structures to last with modern materials.

At this moment in history, building a cheaper 50-100 year house now and letting a future developer rebuild it with hopefully carbon-neutral materials might be more sustainable, assuming that building it to last now would cost more in dollars and carbon and immediate environmental impact. If we haven't figured out how to build in a more sustainable way 100 years from now, then there might not even be any developers around anyway, so it's a win-win (sort of).

Not to mention wood fireplaces in the home and the noxious byproducts they produce is likely to shorten your lifespan considerably.

This is not the case when using modern wood burning stoves though right?
