To answer the OP's questions: No, No, and a big YES!
I did a little 'research' and found an interesting article "This Is Our Place of Worship", and the section "Providing and Financing Kingdom Halls TM", seems to confirm what you are saying. Here's just a smidgeon.
Watchtower TM July 2015, study edition
The work of designing, building, and remodeling them is handled by unpaid volunteers. What has been the result? Since November 1, 1999, more than 28,000 beautiful new centers of pure worship have been provided for congregations worldwide. That means that during the last 15 years, on average, five new Kingdom Halls have been provided every day of the year.
And one more small excerpt from the article:
Many brothers and sisters have experienced great joy in being able to participate in Kingdom Hall construction. Whether we can help out on a building site or not, all of us can have the privilege of supporting such projects through our donations.
Hmmm,,, it appears you are correct, sir!
