How to build a low-level deck on pavers?

[simont]

Hello all, 

I'm planning to build a deck on pavers. Here are some details (also see photo). 

- Deck will be outdoor, uncovered.

- Size approximately 4.0m x 3.6m

- Thinking of joist spacing ~450mm

- Merbau decking 

- Pavers seems stable, however, some areas are uneven.

- Clearance (pavers to house floor level) ~110mm

Some help/questions per below:

- What joist size to use? Is H3 70x45 suitable?

- What footings to use? Is Builders Edge 25-40mm Minifoot Pedestal Feet suitable?

- This should bring the total height: 25 (footing) + 70 (joist) + 19 (deck) = 114mm. Will this cause any issues with ventilation and drainage?

- Will I be better off by building the subframe from scratch (using H3 timber + pedestal feet) OR by using the Good Times module base frame 70x45?  

- Can the deck cover the drain?

Thanks for your help!

Hi @simont 

My apologies for the incorrect reference, I meant to say Bastion 20kg Aggregate Crusher Dust. Builders mix is actually a concrete mix which is something you're not supposed to use for your project.
