I don't think they are benefitting the folks inside-or harming them particularly. JWs will put up with the greenhouse(!).
The thing is that this is a carefully contrived plan to benefit the organization(NY Bethel/WTBTS) rather than the individual congregations-many of whom are fine now with locale and setup as they make sense to the people using them. In my mom's congregation (and a couple I know of besides) halls are in fairly residential areas, down a drive that is not readily seen from the street at all and has a park like situation with lots of trees. Off the beaten track. It serves two small towns filled with a lot of retired people. One town is rich, the other is scraping by, barely. They recently remodeled. I wonder what will become of that hall? It goes against the new guidelines in about every way, plus, there are only two congregations meeting there from about a 30 mile radius. Both towns are small and in the one that is struggling, commercial property can be found cheaper than that nice big residential area lot. Hmm. The hall I grew up in is in a borderline residential area on a main-ish road, but not commercial at all. It's been there for 50 years at least (my whole life).
