Low-level deck on ground

[Janitha]

Hi All, 

I am new to this forum. Having seen some impressive decking projects and amazing member support, I was hoping I could get some helpful feedback on my idea of building a low level deck in my backyard!

The deck I want to build will go over the existing lawn shown in the below photos. Decking surface will be a continuation of the existing patio tiled floor.

 

 

 

Hopefully the below images show the transformation I am expecting to achieve!

 

The ground height below the patio surface ranges between 140mm to 200mm. With the small depth available, I thought of building the deck with 19mm thick decking boards laid over a 90mm deep frame supported on steel stirrup posts.

90 x 45 MGP10 H3 treated pine is what I am thinking of for the construction of the frame. 

I have two ideas for the frame as shown below. Whilst Frame 1 may be more economical I think Frame 2 would be easier to build with the lower  number of stirrup holes that need to be dug in the small backyard. 

Frame 1

Frame 2

I would much appreciate it if you could let me know your thoughts on which approach is more sensible and structurally sound

Looking forward to hearing from you.

Many Thanks,

Janitha

Hi All,

My apologies about the delayed response.

I used Google Sketchup for the 3D images.

The plans were done using Inventor.

Cheers,
