pretty decent set of Wiki writes-up
From what I've seen as a software designer, mostly on the side,
here's how I'd roll with building something reflective that's
200 meters wide, 170 km long, and 500 meters tall:
Start by making something reflective but smaller - like 20 meters
wide, 50 meters long, and 10 meters high - and run with that for
a few years to get the hang of it.
After that, you can maybe scale up by adding something next
to it that's 150 meters long, 50 meters wide, and 50 meters
tall, and keep going like that.
I'm thinking of calling it "agile building architecture" and
patenting it.
The novel is set on Earth in the year 2381, when the population of the planet has reached 75 billion people.[4] Population growth has
skyrocketed due to a quasi-religious belief in human reproduction as the highest possible good.
Saudi-Arabia wanted to build a 170 km * 200 m (widht) * 500 m (height) building/city, outside totally made of glass, including high-speec
trains.

Going from 8 billions now, that reflects a modest population growth
of 20.5% for each 30-year generation.

I've been mystified why they chose a line. Doesn't that maximize
the average distance between two arbitrary points? Isn't that
exactly the opposite of what you want for a city? Or was the idea
to build this out of repeating segments, so a citizen could spent
their life in one segment and would never have to travel the length
of the line?

Remember that attrition occurs.
Plus generations were reckoned
at 20 years but that was 70 years ago when I was in school.
Maybe the 30 year figure is based on data?

That's subsumed under the overall x% growth figure.

I just picked 30 years. "Three generations per century" we were
taught in school some forty years ago and 0.63% yearly growth is
harder to intuitively make sense of. You can fiddle with the
figures, but won't get a more plausible result. It's a standard
compound interest calculation. If you deposit 8 (billion) bucks
now and get payed out 75 (billion) in 356 years, the yearly interest
is 0.63%.

"The World Inside" was just totally different that the
reality of our low middle income childbirth rates
and our old "generations" ideas that it just does
not compare.
Big one, child bearing ages now are quite concerned
with finances and time constraints.
Silverbergs view in that book eliminated those and also
had a special kick of religious duty.

I recall a good deal of near-porn in the book, to emphasize the
social drive to procreate. Its very much a 'casual sex world'.
It *was* 1970, and Silverberg knew what would appeal to his
fans.
Other 'crowded Earth' stories:
Best known is probably 'Make Room! Make Room! by Harry
Harrison (1966), which has 7 billion in 1999.
There's also 'Billenium' by Ballard (1961), with 20 billion.
Probably set in 21st century.
The crowded Earth I'm aware of is "A Torrent of
Faces" by James Blish and Norman Knight. That had an
Earth population of 1 trillion in 2794.

There is also T. J. Bass's two book series, _Half Past Human_ and _The Godwhale_. The population of Earth in that was about 3 trillion
genetically modified humans.
