From 1696 until 1851 a "window tax" was imposed in England and Wales (Following the Treaty of Union the window tax was also applied in Scotland, but Scotland's a whole other legal beast that I'm going to quietly ignore for now because it doesn't really have any bearing on this story.). Sort-of a precursor to property taxes like council tax today, it used an estimate of the value of a property as an indicator of the wealth of its occupants: counting the number of windows provided the mechanism for assessment.
(A particular problem with window tax as enacted is that its "stepping", which was designed to weigh particularly heavily on the rich with their large houses, was that it similarly weighed heavily on large multi-tenant buildings, whose landlord would pass on those disproportionate costs to their tenants!)

Why a window tax? There's two ways to answer that:

, was long considered to be too much of an invasion upon personal privacy (Even relatively-recently, the argument that income tax might be repealed as incompatible with British values shows up in political debate. Towards the end of the 19th century, Prime Ministers Disraeli and Gladstone could be relied upon to agree with one another on almost nothing, but both men spoke at length about their desire to abolish income tax, even setting out plans to phase it out... before having to cancel those plans when some financial emergency showed up. Turns out it's hard to get rid of.).
I recently got back from a trip to Amsterdam to meet my new work team and get to know them better.

One of the things I learned while on this trip was that the Netherlands, too, had a window tax for a time. But there's an interesting difference.
The Dutch window tax was introduced during the French occupation, under Napoleon, in 1810 - already much later than its equivalent in England - and continued even after he was ousted and well into the late 19th century. And that leads to a really interesting social side-effect.

Glass manufacturing technique evolved rapidly during the 19th century. At the start of the century, when England's window tax law was in full swing, glass panes were typically made using the crown glass process: a bauble of glass would be spun until centrifugal force stretched it out into a wide disk, getting thinner towards its edge.
The very edge pieces of crown glass were cut into triangles for use in leaded glass, with any useless offcuts recycled; the next-innermost pieces were the thinnest and clearest, and fetched the highest price for use as windows. By the time you reached the centre you had a thick, often-swirly piece of glass that couldn't be sold for a high price: you still sometimes find this kind among the leaded glass in particularly old pub windows (You've probably heard about how glass remains partially-liquid forever and how this explains why old windows are often thicker at the bottom. You've probably also already had it explained to you that this is complete bullshit. I only mention it here to preempt any discussion in the comments.).

As the 19th century wore on, cylinder glass became the norm. This is produced by making an iron cylinder as a mould, blowing glass into it, and then carefully un-rolling the cylinder while the glass is still viscous to form a reasonably-even and flat sheet. Compared to spun glass, this approach makes it possible to make larger window panes. Also: it scales more-easily to industrialisation, reducing the cost of glass.
The Dutch window tax survived into the era of large plate glass, and this lead to an interesting phenomenon: rather than have lots of windows, which would be expensive, late-19th century buildings were constructed with windows that were as large as possible to maximise the ratio of the amount of light they let in to the amount of tax for which they were liable (This is even more-pronounced in cities like Amsterdam where a width/frontage tax forced buildings to be as tall and narrow and as close to their neighbours as possible, further limiting opportunities for access to natural light.).

That's an architectural trend you can still see in Amsterdam (and elsewhere in Holland) today. Even where buildings are renovated or newly-constructed, they tend - or are required by preservation orders - to mirror the buildings they neighbour, which influences architectural decisions.
It's really interesting to see the different architectural choices produced in two different cities as a side-effect of fundamentally the same economic choice, resulting from slightly different starting conditions in each (a half-century gap and a land shortage in one). While Britain got fewer windows, the Netherlands got bigger windows, and you can still see the effects today.
But there's another interesting this about this relatively-recent window tax, and that's about how people broadcast their social status.
In some of the traditionally-wealthiest parts of Amsterdam, you'll find houses with more windows than you'd expect. In the photo above, notice:
When it was first constructed, this building may have been considered especially ostentatious. Its original owners deliberately requested that it be built in a way that would attract a higher tax bill than would generally have been considered necessary in the city, at the time. The house stood out as a status symbol, like shiny jewellery, fashionable clothes, or a classy car might today.

Can we bring back 19th-century Dutch social status telegraphing, please? (But definitely not 17th-century Dutch social status telegraphing, please. That shit was bonkers.)
