Im seeking a bit of advice from the experts.
I am planning to put in a low lying deck in the backyard. Semi circular in shape, but I am have a bit of a head-scratcher on what the underframe should be shaped like. I was wondering if anyone knew of any websites with blueprints or design plans for such a shape, or of course any other helpful information would be appreciated.
The frame would be the same as a rectangular deck. The issue is at the edges where it curves. You need to decide what material you'll be using to wrap the edges before you design the curve. Synthetic boards will have more give to them then regular wood unless you laminate thin boards to the edge, one layer at a time. The issue with thin boards will be the faster deterioration.
