More broadly on this subject, I recommend that every software engineer read the book How Buildings Learn, by Stewart Brand. It's a book about the lifecycle of buildings, design compromises, and how buildings are altered and repurposed over their life. It's a fascinating way to think about software as well.

Is there any reason to believe that the "old" building wasn't just recently repointed? This seems like the most likely answer.

No amount of repointing could make the modern joints as even, or as narrow, as the old ones. Though to be fair I don't think the modern builders were even going for that look.

Is the brick actually holding up the building? In many modern buildings, it's just a veneer, about 1cm thick. The steelwork holds it up. The new Box.net HQ in Redwood City looks like a brick building, but it's not; it's steel and concrete with about 1cm of brick on the outside. There's some nice work being done with brick today.[1] Some of this is gentrification, built to fit in with existing brick buildings, or to i…

> Is the brick actually holding up the building?

This was my thought as well. The modern building is likely just using the brick as veneer, even if it is full-thickness brick. It's likely concrete walls with brick layered over it. The fact that the brickwork is poorly done likely doesn't matter except aesthetically. If all the brick fell off the building would still be standing.

The newer building is indeed ugly, and the brickwork looks cheap and poorly done. But that doesn't mean the technology has declined. It means the technology has advanced to the point that the brick is just ornamental.

The article uses the word "façade" 7 times in reference to both the older and newer building. My takeaway is the emphasis on "technology" in the article is on form rather than function.

Survivorship bias is a really important caveat: https://en.wikipedia.org/wiki/Survivorship_bias Many cheap brick buildings from 100 years ago are gone, where the high quality ones are more likely to remain. Also, steel Lintel are often used over windows in brick buildings. They don't last as long, but are fine for cheap construction that is not expected to last. AKA the kinds of building that are unlikely to be aroun…

not only that, but back in the day brick was the fancy expensive option, today it isn't. those with big budgets and ambitious design goals choose other materials (steel, glass, etc.)

I thought brick was more expensive today due to labor costs and that steel and glass were comparatively cheap. Is this false?

Yes, but when you have entire rows and city-blocks of colonial-era buildings standing, and entire cities of century homes where many new office buildings have gone up and been torn down in the meantime, it's hard to just point to survivorship bias. These aren't a few isolated cases, but large contiguous seas of old buildings.

Earlier quoted context omitted.

I suspect that survivorship bias is not much of an issue here since the old building still looks a lot better than that new building.

Actually that confirms the point; the old building was clearly state of the art for the time, and the new building is a cheap rush like student dorms sometimes are.

No, there are many buildings in London surviving that were built simply to get the money when they were demolished to build railways but it never happened, and they are still standing. 19th century buildings were mass produced, not always very well.

Survivorship bias means that the only objects available for comparison are ones that bias the comparison. For example, the brick buildings from 2,000 years ago were built way better, because look at this brick building still standing that was built 2,000 years ago, look how great it is! Of course, the bad brick buildings built 2,000 years ago can't be found because they crumbled a long time ago.

My last house was built in ~1936. It was cheap for the time, but the entire estate of houses it sat in was complete - virtually nothing had been removed. The form of the buildings had changed somewhat (extension for bathroom instead of toilet in the garden), but the brick walls were incredible and the internal timberwork (joists, frames, etc.) was all hardwood of a quality that would be very expensive now.

My current house was built in ~1985. The brick quality isn't bad, the walls are much straighter, but the wood is cheaper and the materials thinner and lighter. It might be the case this place will last 100 years, but I wouldn't bet on it. It's a middle market house, for the time, not cheap but not high end.

While survivor bias is important, where I live (London) the main reason houses from 100 years ago aren't around now is simply the war. The stuff from then that's still about - including "cheap" factories and other stuff - is now wildly fashionable and still well-built. Stuff built in the 50s was laughably awful and a lot is gone, stuff from 60s and 70s is going the same way. There are definitely other things going on.

I think even some old (100 year old) buildings w/ "full sized" bricks (not 1cm veneer) are still wood-frame construction w/ brick non-structural outerwork.
