Decking over an existing raised patio

[dediy]

Hi guys

I'm looking for a bit of advise regarding building a deck over a raised patio. Basically the patio is attached to the house and is 10m x 4m and has a retaing wall all the way around it. The paving slabs are resting on a hard core base, which is probably just under 1m from the ground.
Can I run 6x2 or 8x2 joists from the house across to the retaining wall and then maybe dig a post half way across (2m) into the hard core?

Your thoughts are really appreciated.

Depends just how high above the flags you want to fit the decking.
if it is ok to sit it on the flags--here is a good tip for you .

Just have a look out for some Euro pallets -they should all be the same dimensions .
Lay them on top of flags -screw them together-- use slate or decent packers to level them up-- and screw your decking to the structure (pallets).
Very cheap and LOADS quicker and easier to do.
You will then have a 'floating deck'-- Just like a floating floor !!

Trust me-- it works very well .
