I have an area that is about 4' x 2' that I want to put off the main surface of the deck as an entry way to what we call a 'Turtle Garden". This area will be parallel to the ground and about 8 inches off of it.

What I want to do is make the pad surface like a non-standard parquet - not standard widths or lengths or patterns. Some parallel, some angle, etc. Something to do with all the 'scrap' I have and something to keep me busy before the wife expands her Honey Do List.

I would build the 'frame' with 2X beams and anchor bolt them to the band board, but am uncertain what would happen if I placed 6/5 horizontal every few inches to act as anchor points. This area will get little or no traffic.

Hard to describe, but basically I am thinking about building a 3 or 4 inch 'grid' with 6/5's as joists and then securing decking board of varying lengths and widths to the top of this grid. Do they need to be 2X as well or will 6/5 work with such small grids?

Is this nuts?
