Hi everyone, I am a DIY homeowner and am planning to build a deck on a sloping site at the bottom of my garden, approx 6m x 3m. I have calculated the quantity of 100 x100x2.4m posts and 150 x50 joists etc., with posts at 1.8m and joists at 400 centres. Before I order any timber I have a question about the 100 x100 posts. Because the 6m length of decking will be raised about 500mm above the ground, I am concerned about making the handrail rock solid. Should I cut 2.4m posts, set in concrete, around the perimeter long enough to fix the balustrade and handrails directly to them, i.e. 1100 mm above the decking boards. Or will it be sufficiently strong, and look better, if I bolt newel posts to the joists? I think the first way will be stronger, but may look a bit naff. Any thoughts?
