Having seen other German words, I'm going to just blindly guess that the word etymology is this:

Fachwerksbau

Fuckworks Bau

Sex worker Bough

Sex Dungeon Beams

Yep, fetish harness house.

and no trees! yuck.

You can stick a fancy facade on basically any wall construction to make it look like an old-half timbered style, or brick, or stone, etc.

But trying to actually build an old brick/stone/plaster and timber monstrosity today wouldn't be smart. Insulation, moisture control, energy efficiency, and even creature comforts like wifi signal penetration are all miles better with newer construction methods.

I agree the architecture is boring, but again, it doesn't have to look this way. However, I think most people would rather have the soulless gray box than have uncontrollable mold spreading across their walls unless they leave the windows open in winter.

Yep, I've lived in old buildings most of my life (very german predilection for the "Altbau" I guess) and I'm not sure whether people are aware how much energy it costs.

I love 3.5m ceilings and 2.5m high windows, I love thick walls made from solid stone, that's how I grew up, in a rented place in a wonderful turn-of the century building. ... it's not even expensive to rent compared to where I live now. But heating alone costs enough that it could pay for a single room somewhere else. And given that the walls are thick, but not insulated, you have to make sure you heat it, make sure you don't put things too close to the wall, otherwise you might have to battle moisture and moldy walls. In fact, if the windows insulate too well it might even be a drawback because the moisture can't escape, and you have to air the rooms (the very german habit of "Stoßlüften") frequently to not get mold.

The rectengular zero-energy buildings of today, you probably don't need to heat much. Friends of mine used to live in a building like that. Well insulated, three-pane windows, all that. They barely had to turn the heat on in the middle of winter. Body heat, residual heat from cooking and what not, it's practically enough to keep the place warm.

Yeah, I'm looking into insulating my 100+ year old house, and it might mean the stones on the base need to be flattened and covered up. The windows and some of the doors are now plastic, since the previous ones (that were already not the original) were water damaged, which somehow involved the indoor doors too.

Unless you build the house to last 200 years, with occasional maintenance. No drywall monstrosity will survive that long.

I live in the Philadelphia area and a lot of the row houses here dating to a century or more ago have absolutely beautiful brickwork, incredibly creative and interesting stuff, often on houses that these days barely sell for $100K. It would be completely impossible to duplicate this kind of thing today even with a construction budget of millions. The craftsmen who can do that kind of work are nonexistent now -- today you're lucky to find somebody who can lay bricks in a straight line.

There are a lot of high density housing being built in my city after some planning rule changes to enable it.

It's unpopular to say the least.

I'm just happy that it means more people get to live in a house.

At least all the things I see on the buildings in the top picture seem to have a utilitarian purpose.
Of course, how well they fulfilled their purpose would have depended upon the availability of materials and manufacturing processes at the time.

The popularisation of the idea that ornament is inherently bad genuinely did far more damage to the visual environment of the UK than the Luftwaffe managed with years of strategic bombing in my view.
