"This could be due to the fact that they built in a subdivision that has restrictions and may have been forced to put them in."
This is a valid point. Quick build standardized plans do not come with windows. I'm alittle rusty on this, but the local elders (congregation) have to ask for them. In one city in Texas the brothers took the standardized quick build plans to the city to get a building permit. The city denied the permit, said the congregation must hire an architect, structural engineer, and comply with building code. Architecturally the code reads that every x number of feet there will be a column, corner, window, or other architectual feature. The city further told RBC, "your not building an ugly box in this city".
Of course the QB brothers were arrogant and difficult trying to push the matter, but the city won. Cities now have master planners and are trying to build more aesthetically pleasing buildings in the community. I can see their frustration. What if someone wanted to build an ugly house next to yours?
In rural areas the standardized plans are just built with little regard to building a beautiful building. David and Solomon would be ashamed.
