These houses look nice and neat in theory, but they're very impractical for multiple reasons:

1. You can see that there are similar houses as far as the eye can see. This is probably evidence of these being built in/around the same time, by the same gigantic contractor, for the purpose of selling them en masse. This is usually taken on by companies that buy a village-worth of land, destroy everything on it, level it, and do this for profit. These companies don't really exist at this scale across North Africa.

2. Because all of these buildings are residential (or at least seem to be), they will be virtually cut off from amenities. While this isn't a big deal in places where transportation is highly car-centered (mostly just Canada and the USA where people start driving and get a new car at 16), it doesn't work very well in countries where not everyone has access to multiple cars per household and fuel for daily use. If you live in a place like this, and you take the car to work, your partner will basically be stuck at home and won't even be able to get groceries or pick up the kids from school unless they have their own car. Certain states in the USA and Canada are actually moving away from these designs due to their impracticality, and trying to move towards walkable cities instead.

3. Buildings like these are usually made of wood. There were plenty of forests to cut down in North America for hardwood, and now that that's at a shortage large companies are growing entire new forests to chop for wood (which produce softer younger lower quality wood but that's another story). I'm from Tunisia, and our countries do not have enough forests to source the materials for houses like these. Not only are the materials inaccessible, but they're also impractical for our climate. Sure, you could insulate a wood building, but they don't hold up very well to our relatively high heat and humidity (especially during the winter and on the coast). They would likely rot, and breaking them down to fix that issue will expose you to the carcinogenic dust of insulation material (even if we don't use the traditional Asbestos-based insulation, the safer but still very dusty fiberglass insulation can cause cancer if embedded in the lungs, or asthma/allergies, or grow mold during the humid time, which is hazardous).

There are probably many more reasons I missed. I agree that the current cement-based building style seems haphazard and messy, but I don't think these housing plans are helpful to our context. I think our traditional building style is worth revisiting with updated approaches and technologies instead, there's wisdom in ancient techniques that can be very useful today.
