Why this site exists

Pass the trade on.

Let's Build Stuff began as Sun's Up Construction's training library: a way for new carpenters to learn the job without pulling a lead away from the work. We're fourth-generation carpenters, and passing the trade down is the point.

The lessons were useful to our crews, so we made them public. Homeowners, apprentices and working carpenters can use the same free reference, with steps, quality checks and help when something goes wrong.
