Yes it does.
If I live in suburbia surrounded by suburbia, my house is worth X, because it's a house in a quiet area. I have to drive to SF to have fun, which sucks because it's far, traffic sucks, and parking sucks.
If I live in suburbia but am surrounded by islands of new mixed-use buildings (housing on top, retail on the bottom), then my house is worth X + Y, because a) it's still a house in a quiet area, but b) it's now also close to walkable outdoor spaces with chic shops and restaurants, at least one of which is likely to become a popular upscale haunt.
I now have the luxury of being able to quickly drive there in my car to hang out, and then quickly go back home to my (large, quiet) house when I'm done. I get convenient use of the new space, without the inconvenience of living in an overpriced shoebox above a nightclub.
It's literally having your cake and eating it too.
