Summer house and decking base

[Keitai]

We've built a base for friend's summerhouse on higher ground then we're planning to build another one with the joists equally apart on lower ground. It's been pointed out to me that the joists (2inch by 4inch) are too far apart. Approximately 1 metre apart. Its 4m x 4m so 16 blocks.

How do we get round this? Joist hangers?

your decking looks a bit high it need planning permission if its higher 300mm above the ground level
is it less than 300 at the back ??

The joists on the higher ground are the base for a summer house. That's what is going on top.

your summer house needs to be below 2.5m and no veranda or platform

I think the decking might be close to 30cm. I cant see my mate's neighbours caring less. It's s run down working class area full of foreigners (including my mate, who's Turkish).

Regarding the summer house they might care a bit more. I'll be sure to tell him. And thanks for the info for future jobs when I'm working for posh people.

Pretty much finished the decking on lower level. My friend bought himself some lights off ebay for it.

Couple of questions, the base wasn't square so on the right side (as in picture) it is different widths. Should we just widen the narrower end with joist hanger or cut a board with jigsaw (scribed in)?

Going to cover the gaps near wall with something too

You was told about it being off square,but choose to laugh it off,if i done that, i would hang my head in shame,and look for a job with Deliveroo or similar.

looks like you should have started at that side to get the boards square and avoid all those wedges
are they screwed down yet ?

Yeah. Wouldn't a few joist hangers sort it with 6 inches of joist sti cking out. I told my mate to measure the diagonals when he was levelling the blocks

joist hanger to where ??
a joist hanger that just supports an end is a hinge ??
how much space do you have far end [the overhang to the other decking]??
my thought are a timber screwed at right angles to a point level to support a full board end
then an additional short joist stopping at the point coming forward to be within the width screwed to the joist
and a block/brick or whatever is required to support the joist in case off bounce
