The building materials supplier had promised hemlock stair parts would be delivered two days before our target completion date. Eric, the finish carpenter, was ready to install the stair in a day. Then, they flaked out on us, saying it would be two more weeks. We needed Plan B.
We found that MacBeath Hardwood had clear, vertical-grain douglas fir in stock in rough 4/4 thickness. So, we bought a couple of hundred board feet of the material and planned to set up our own mill to make the flooring, treads, and risers. MacBeath delivered the material to the job site in FOUR HOURS. The wood was beautiful and mostly in 14-16′ lengths. Had I known how nice this material was, I would have used it for door/window casing too. (However, it was expensive…about $6/bf for the rough material.)
I love the steel stair. The architects designed it conceptually. I worked out a bunch of structural details. The detailer at the steel company created the detailed design. We iterated three or four times to get it right. This stair cost about $3000 for the steel. Waaay less than having some fancy pants stair company do the design and installation. We’re going to use big, chunky treads (3-1/2″ x 11-1/2″), probably out of reclaimed douglas fir (although they were dimensioned such that pieces of a glulam beam turned on their sides would also work).
The railing still needs to be welded in place…but I love it, even in its rough state.
One detail I really like is that we set the steel side stringers on 3/4″ spacers so that we can slip the drywall behind them. The stringers will serve as the baseboard and we’ll get a nice clean interface to the drywall.
