I have a freestanding deck that is 24 ft across at house and 10 ft out and is only 14 inches of ground ,frame is on piers .I am not attaching to block of home.
I had to pour piers about 10 inches from side of crawlspace block due to footers and pier size.
What is the best way to build a small support (for the 2 24 ft deck boards) in that space between the block of home and the beam of the deck that sits on center of pier?
Pic shows doorway at edge of beam with a space for 2 rows of decking.

It's framed wrong, there's no cantilever on the outside edges.
That would have taken care of the now exposed piers and let the rim joist be closer to the house.
Sort of like this.

I can add 2 by8s to the sides but will need something for inside area

Is low an no room for lower layer of joistsas in your pic.But can extend sides.
If I have to attach a 2by 8 to that area of concrete block at home for that small area I will..
Can also dig a few deep holes an use 4by4 as support .
So many ways but I'm just looking for best options being ONLY13 or so inches off ground an just 10 inches out from home.

My 2nd pic is just example on how some are done.

Main deck is VERY SOLID! 12 inch center an 15 piers.

According to the first picture you will need more nails/screws in the treads.?

Most pics here have space for a lower wood support under the frame..I have just over a ft if even that from ground to door step.
As in before pic -just as example- showing a piece of 2 2 by 10s (by 24 ft along home) in support with deck board before before placing in concrete tube

Guess i might go with bolts, for another 2 rows of 2 by 10 x 12 ,along the concrete block and then add bracing between both 2 by10 s for the 24 ft..its only a 10 inch wide area of support .

in ground 4 by 4s are also a possibility or deck support blocks but i dont like to use either of those .

Not done with attaching end board in pic in case i need to get to inside of double beam while building end block to home.

Just looking for suggest before i build it..

Thank You

Yep, second photo that Ron45 posted. 10" is enough room to screw them to rim board. If you have a walkout from the house, make sure that area is very strong. Not sure if that would pass inspection, but 14" off the ground, a lot of places won't require inspection.

Thanks for the suggestion.
-would that verticle side attach to block or to the beam ?

I was looking at maybe a set up like in pic- with the 2 side boards added to outside -brown- an end board -blue- to the concrete block,an the red -blocking between them..pic is framing alone without decking boards,,
This is a lot more wood though ..

You can split the beam and run a double joist through the middle all the way to the house. Run both end joists to the house. Run a double rim (up close to the house) between them both sides of the doubler in the middle.. Then ladder block (little joists) between them.

You can run a hanger upside down to carry the rim at the house on the middle doubler which is supported by the beams.

I decided to go with 2 by 6 bolted to concrete block.
I will be to be using the 2 by 6 along the concrete block and use joist hangers and bracing to connect to beam.

Thanks for all the suggestions!
