Tom Silva shows Kevin O’Connor the progress on the new back deck at the Lexington house, and how the architect has called for a corner stair leading down to the backyard. The framing requires two sets of traditional stringer systems, joined in the middle by a hip stringer and a series of jack stringers; the same idea as framing a hip roof. Then Kevin and Norm Abram finish up the trim and decking on the new corner deck stair. For the ipe deckboards that are sharply mitered in the corner, Norm has settled on using a floating tenon connection to prevent them from opening up over time.
