What’s up with these mashups?

Been seeing these pop up in my neighborhood. Of us tear down most of an older home however hold a part of a wall up. Then construct one thing the place the previous bit doesn’t match aesthetically in any respect (IMO). I’m considering the saving of a part of the home may very well be a tax factor however why make them so ugly. Why not go for bizarre just like the (clearly tremendous costly) Royal Ontario Museum that melds previous and new in a fantastic means
