I absolutely would if it was suitable for me! I absolutely love the mixed zoning buildings they have through large parts of Europe where it'll be a couple of houses on top of a small business. We have them around here, too, but they generally seem to just be for the people running the businesses and are rarely rented out to the public

I remember watching a video a while ago which I believe was either on Hong Kong or Singapore. Basically, they built train stations under or at ground level, then they built gigantic towers on top of them which had shops, houses, and offices all in the one building. I'm not sure about offices, but that seems like a dream to me. Certainly wouldn't need to bother with a car, that's for sure

Also I'm willing to bet like most damn apartments in this country, they won't bother with noise proofing and adequate insulation, and the bottom 4 or 5 floors will basically be unliveable from all the noise in the shops, including all the screaming Everytime some drunk person gets caught stealing by an overzealous security guard desperate to use their karate training on a real life person)
