Having recently gone through a building program with my church, I found the following comments from Victor Hamilton's Exodus commentary to be interesting.
Victor P. Hamilton, Exodus: An Exegetical Commentary (Grand Rapids: Baker), 2011), 456.
"It is also significant that Moses first asks for donations to fund the project before he talks to the people about the tabernacle’s design. One might expect that order to be reversed: first show them the plans, and then ask them to get behind it financially. Is that not how most religious communities wishing to construct a new building or expand and renovate an older building would go about it? Congregants tend to be more enthusiastic and generous when they can see, at least in blueprint, what their pledges and dollars are funding."
