With the way they’re building homes today, you’re not going to start building by going to a vocational class. Of all the things you learned at the Hab house, mutiply that by a hundred fold. Electrical,plumbing,concrete,phones,network, code books, and most important, structual enginering. I appreciate your desires,but, you don’t learn this in 2-4 years,even working full time at it. Keep going, but, be relistic. Ron J.
