How Long Would Buildings Last Without Humans (And Why?)

Exact Answer: 50 to 60 years

There is no way to understand for sure that our home is going to remain for 80 years or even 150 years. It chiefly comes down to a few essential circumstances that can impact the uprightness of our building and reduce that timeframe drastically.

It is a highly debated topic inside the construction industry since it is dependant on the materials used, the nature of the craftsmanship, and the maintenance that is needed and accompanied by it solely. On mediocre levels, the usual expected and acceptable lifespan of buildings should be at least 50 to 60 years. However, many believe that the lifespan of a building is much longer than that, reaching over 100 years.

How Long Would Buildings Last Without Humans?

Type of BuildingsLifespan
Independent Buildings30 to 40 years
Apartments50 to 60 years
Any Ideal Construction 75 to 100 years

Things that are under continuous use like water pipelines, power cables, and other related services get deteriorated over time and worn out after a fixed duration. However, independent buildings age much slower than apartment buildings where the facilities and common services are shared between the society residents.

It’s well understood how long a building can last on average. Many factors can influence the longevity of how structurally articulate the building is. Knowing these factors before and after the build is complete can help ensure that it will withstand time and the obstacles it will go through. Lack of maintenance or inadequately implemented maintenance can lower the lifespan of a building by a great deal.

Why Would Buildings Last That Long Without Humans?

As stated before, buildings are all made up of elements and should be replaced if they fail. Other than a flooded foundation, any part of it can be replaced. The factors include:

  • Materials: A building out of materials that are sustainable and of high quality can make sure that it is going to be standing tall for generations to come. The things used more frequently are going to degrade faster over time, so be sure you invest in the right products for your home to last many lifetimes. Materials that can last a lifetime (60 to 100 Years) include Natural Stone, Clay, Concrete, Bricks, and locally sourced materials.
  • Craftsmanship: The factor ensuring that a building has a long lifespan is excellent craftsmanship can avert issues arising too soon due to uncertain damages or a seemingly harmless crack. Poorly built buildings will degrade much faster than the one that has every little detail paid attention to. Ensuring that this does not happen, they are put through detailed assessments at each stage of the construction, from measurements and materials to assessing possible outcomes of each decision made.

Spotting a builder or a contractor who comes profoundly suggested is the best bet at ensuring good, quality craftsmanship on the building. Clumsy craftsmanship and poor design can come with concerns, replacements, and repairs much sooner than they are expecting.

  • Weather or Environment: Regrettably, nature is something that we can not control, and it is the same when it comes to a new building. One needs to ensure that they build it for the environment that it will be in. It should be able to endure years after years of harsh circumstances and whatever else nature chooses to hurl at it.
  • Maintenance: Objects get old, whether they are living or non-living. They are compelled to wear and tear, damage, and break. It is no different from a new building. One may not need to do too much maintenance within the first few years, but it will come. Keeping on top of the care that a building requires will ensure that it is going to last longer. The buildings are made up of different elements. While it may be sound for many years, the components that make a building a shelter may not be as resilient and last as long.


Hence, a building can last for only 50 years or maybe more than 100. It is very unpredictable because each of them has its unique capacity. The best thing we can look after is the better we maintain it, the greater it will remain. When it comes to increasing the lifespan of a building, there are a few measures that should be looked after.

A part of it gets down to basic and necessary routines that can prevent disaster from striking. Checking regularly will allow us to grab new damages, cracks, or wear before it becomes too expensive or repair or restore collectively.
