Building stairs is pretty easy after you get done crying about how much the lumber cost you. The 3 stringers would be 2x12x16 or 14 at $90 each and for the treads you would need 7 2x6x12 boards at $30 each for 3' wide treads. So you're looking at $500 just for materials. I have a book I can lend you if you want to build them yourself.
Thanks, Dave ( my hubby) says the only problem is that he already knows he won’t like the formula results.

The space we have for the stairs to go doesn’t seem like it’s really enough room. So, they are either going to be really steep stairs or come down a bit and then turn.
