Curious about Building Brokers

Has any one ever used a building broker before?

I read in a recent API - one of the editorials featured a resi IP owner using a building broker to find/tender a builder for a 10 unit project.

I find the concept interesting.
Building Brokers generally (check that - it changes case by case) own the copyright over your plans much the same as a builder does.

the Broker then ships the deal out to a panel of builders and gets paid a commission - anything from 1.5% to 5%.

i give my clients full copyright over the plans for their block, but i retain copyright over the individual plans entirely, so if they're used again, it's pay day.

there's a big difference there.
