- dlahoda 2y ago60 years is way small. one person could have move in the end of of life. it should be 200.
- bluGill 2y agoI live in a 50 year old house and there are a lot of things we wouldn't do today. The walls are not well insulated and hard to retrofit. The attic meets minimum standards only because I added extra myself a couple years back - I wanted to do more than the minimum but the way it is built there isn't room for more. At least I avoided aluminum wiring (which was common a couple years before this house was built) but there is a lot about the wiring that doesn't meet todays standards. It isn't just style that we layout houses differently today. This house has been remodeled at great expense (30 years ago) and there are some things that are still wrong. Which is to say tearing down and building new to the latest standards is a good thing.
- littlestymaar 2y agoI live in a house that was built in 1840, and none of the issues you're complaining about exists here, since I had everything refurbished when I bought it. Destroying an entire building to fix the wiring or insulation would be insanely wasteful. Concrete is one of the most CO2 emissive technology, and it also consumes way more sand than what natural erosion produces, and thinking that all of this will be rotten in a century is heartbreaking.
- medo-bear 2y agoI also refurbished my 50 year old apartment which is part of a cute concrete monster i wouldn't change for the world. I've had no issues doing this and attained the highest possible energy rating because the architect that designed the building was a genius.
- littlestymaar 2y agoThat doesn't surprise me, the problem with reinforced concrete starts getting out of hands around a century.
- medo-bear 2y agoI think you are overstating the problem. No one expects these buildings to start falling apart any time soon
- littlestymaar 2y agoIf they are 50 years old, they are already, it may be hidden but the concrete cancer has most definitely kicked in at that point. Don't worry it's not going to have dramatic structural impact for the next 50 years, but at some point the bill will start coming to try and keep the building from falling apart. Until it's not economical to do so…
- medo-bear 2y ago> concrete cancer You mean decay ?
- littlestymaar 2y agoI mean this: https://fr.wikipedia.org/wiki/Carbonatation_du_b%C3%A9ton#/media/Fichier:Betonrot_Hippodroom.JPG https://fr.wikipedia.org/wiki/Carbonatation_du_b%C3%A9ton#/m...
- medo-bear 2y agoSo decay
- littlestymaar 2y agoCall that the way you please, it's also called “concrete cancer”, and I find the expression much more apt.
- littlestymaar 2y agoNo I'm not, getting reinforced concrete to last beyond a century requires an increasing high amount of effort, which isn't the case with most other building materials.
- medo-bear 2y agoSuch as ?
- littlestymaar 2y agoStone, rubble masonry, brick (both fired and mud), wattle and daub or non-reinforced concrete! As long as you keep a roof on top of them, you'll have mostly local/superficial degradation, but with reinforced concrete you'll eventually end up with concrete cancer everywhere which is harder and harder to fight.

- medo-bear 2y agoNone of these come close to the performance of reinforced concrete in highly dense urban areas. They could be used in non supporting walls sure. I live in a statically outstanding building (very important where I live) that is over 50 years old and my apartment has the highest energy efficiency rating possible. The latter is not due directly to use of reinforced concrete but architectural design enabled by it
- littlestymaar 2y ago> None of these come close to the performance of reinforced concrete in highly dense urban areas. Paris, which is mostly made out of stone buildings and is among the densest city on earth, disagrees.

- Fricken 2y agoBrutalism has been very popular in civic architecture due to it's appearance of megalithic permanence but humans find it so ugly that a great deal of brutalist architecture has, ironically, been torn down.
- medo-bear 2y agoHumans also find it appealing and keep building brutalist architecture. Some other humans pay astronomical amounts of money for such pleasure https://en.m.wikipedia.org/wiki/Sirius_Building https://en.m.wikipedia.org/wiki/Sirius_Building
