To build a low level timber deck approximately 25 cm of the ground

[Chye]

Hi, I plan to build a low level deck, 8.5 meters long, 3 meters wide on one side and 3.5 meters on the other. To cover the 8.5 meter length on the front I plan to use 125x75 treated pine as the bearer whilst I plan to lay a 75 x 100 bearer flat on gravel or supported with concrete pavers in the middle and close to the house wall. The 100 x 50 joists will be screwed into the bearers laying flat and then attached perpendicularly to the front bearer with joist holders.

Is this workable? will this be stable and secure enough? I'd appreciate some feedback about laying the bearers flat on the ground from anyone who have done this before.

Thank you for your help.

Thanks Dean. I plan to stabilise the bearer furthest away from the house with post holders. Will also consider other options to stabilise it.

I come up with a span of 480 to 760mm for MGP12 or 310 to 520 for MGP10 or F7. on commercial decking.

Residential 1300mm for MGP10 or F7.

Huge difference between the two standards.
