I am not sure if you are discussion about legitimate construction or The Sims.
If it's real, contact a housing plat developer and ask if you can intern or regard without pay envelope for a while. You can learn deeply.
Answers: Get a job next to a builder. You would have to start as a laborer and cram on the job. After a few years you can work your channel up to being a carpenter.
