It is true. The Society is simplifying all of their structures/buildings. Many of the more elaborate ones are becoming maintenance headaches. They have recently released new simplified KH plans.
Additionally, they are even selling off many of their assembly halls. The word is that the Assembly Hall in plant city, florida will be sold, and a new simpler Assembly Hall will be built.
While the new Kingdom Hall plans are still fairly nice - the assembly hall plans actually look like big produce warehouses - you know, made out of that corrugated aluminum with a nice lobby is all - so that maintenance will be much easier and add-ons and mods will be modular in nature.
I expect you will see this slowly trickle across the country if it hasn't started already.
