High-end houses aren’t square in the same way that a normal house is square: often they’ll be open plan, where rooms join together through shared spaces that are all sorts of shapes. A better description of the consistency amongst property is “straight” walls.

If you spend much time looking at high-end real estate, you’ll encounter much more than just the standard square rooms you would see in the average house, but ultimately, they’re still square(ish) because straight walls are convenient and practical.

I think the best description would be “right angles”.

Ultimately, not only is furniture designed for right angles, but so are all the construction materials and equipment. Doing anything else is custom and more expensive but also not usable because of the furniture limitations.

The best you can get without going into custom stuff il are those bay windows that pop out.
