Deck Design

[LineLefty]

Hi all, I know I havent posted anything in a year or so......a toddler and a newborn have prevented any shed time

Never the less, I'm going to post a plee for help.

The garden designer has come up with the attached design. The original idea was for a PAVED path/circle leading form the driveway to the house. SWMBO has now proposed that it be a boardwalk/deck.

There's a myriad of different ways to construct this curvaceous monster. But is it a a deck.......or is it a boardwalk?

Concrete grade beams or really, really, short timber posts/joists bearers? Decking configuration? Tapered? ITs all getting a bit overwhelming.

Any advice on first principles design would be appreciated!
