Description
A deck extension engineered from the ground up to carry a future hot tub: three 12-inch concrete piers dug roughly four feet deep, 6x6 posts, and a triple 2x10 beam under joists sistered 16 inches on centre. The new boards run in a staggered pattern so the expansion blends into the existing deck, with railing posts anchored inside the joist cavities for a rail that does not wiggle.
