Box-Framed Curved Deck Stairs

A fun and challenging project that I’ve been working on lately is a new elevated deck, which features the set of curved stairs shown here. Instead of framing the stairs with cut stringers, I built a series of tapered boxes out of incised pressure-treated hemlock, standard exterior framing lumber here on the West Coast. The boxes are all 6 feet long and taper 5 1/2 inches in width from one side to other. Stacked on top of each other, the boxes form the framework for the stair’s treads and risers.
