Who the hell "likes" sharing walls with people?
I have no problem with it, if it means I get to live in the city. It's a compromise.
I personally was so happy when I could afford to live in stand alone houses. I now, don't have to listen to other peoples noise (stereo, crying babies, fscking, etc)...and I don't have to be terribly cognizant of my own levels of noise production.
You need to insulate your walls better.
I like having a back yard, where I can plant and grow a nice sized vegetable garden, where I can set up my smoker and my grills....where I can set up my homebrewing apparatus, where I can set up and invite friends over for a large crawfish boil, etc.
You can do that in terraced houses as well. Most in Belgium have a yard extending straight back from the rear of the house, the same width. It's not huge, I'll give you that, but plenty large enough for most activities.
Why would I possibly, want to live in a smaller box, share walls, and have to squeeze all my outdoor fun on some small balcony, that in some places has regulations against open flame outdoor cooking?
Because a city is one of the few places that has anything interesting within walking or biking distance. I don't want to have to drive half an hour to get to the nearest restaurant, cinema, museum, or even the supermarket. There's more to cities than just partying, and I want to live in a place where I don't *have* to use my car if I want to do anything besides stay at home.
