Suspended floor in shed/garden studio

[Jagosdad]

We have had a large 7x5 metre shed built in the garden. It's going to be my wife's home office and will have visitors.

The shed is built on top of what are basically railway sleepers (or the new equivalent) so has plenty of breathing space under it. However because it going to be an office I'd like to insulate the floor. I imagine this means I need to build a suspended floor which I can insulate under.

My question is how many joists will I need to put under the suspended floor or rather what the gap needs to be between them?

Many thanks for your help

400 mm centres will be fine.

you do realise if it has sleeping accomodation you need planning permission
although the odd night would probably not be noticed if you keep in with the neihbours

Thanks for your help.

I will go with 400mm gaps.

Think I may have confused the issue mentioning visitors. I meant business visitors during the day rather than friends etc staying over!

if its under permitted development it ok but if you ad sleeping accomodation [or plan to sleep in it]it needs planning permission

yep cleared that up

i only mention it because so many companies sell garden building and forget to mention that sleeping requires planning

When it comes to the actual insulation, I assume that I will need to leave a gap under this?

So I am left with from the bottom, the original floor, air gap, insulation and finally the new floor?

Is this right, even though there is a big gap under the shed?

Thanks again!
