We had some proper heavy 'Shifting skates', that assuming the surface

We have also moved some heavy stuff on wooden rollers (round fence
posts), but the problem you may have is getting the shed up high
enough (without damaging it) and keeping control of it whilst doing
so.

I thought about sliding it on something slippy... plastic boards or
something.

Yup, that could work but maybe only depending on the rigidity of the
boards and the firmness of the ground (to stop the boards flexing and
corners / edges 'digging in').

Although it would need some means of exerting force on it -
isn't so easy to push as it's in a corner.

I think pulling and from low down might be the safest thing.

What is the actual shed made of as that can make a big difference re
how much distortion it can take? If it's plastic panels with a wooden
floor then you might easily stress the fastenings. Also, what are the
slabs resting on, just earth?

It's all wood,

That could make it heavy or light, depending on the construction and
wood. ;-)

except some polycarb for the window which can probably be
taken out.

I think if it got as far as distorting the panels enough to break the
polycarb you might have bigger problems and the polycarb (depending on
thickness) might help keep it all together. ;-)

I think the slabs are just resting on earth, although I can't
tell because they're underneath the shed

So will it be moving over the same? eg, Will you be moving it off
slabs on earth to more (yet to be placed?) slabs on earth?

I think if the slabs are a complete patch (rather than just at set
positions like corners and the ends / middles of the bearers) then I
think you are still in with a chance. If just the corners etc, that
could make it much more difficult (depending on the strength of the
shed and your pulling power).

If the whole structure is reasonably strong, strong enough to be
listed up by one edge, a few long levers along one edge allowing you
to get some timber under the bearers (assuming there are any) might
give you a start?

I did wonder about some kind of pulley/ratchet arrangement, but there's
nothing secure enough to attach the pulley to.

A h/d strap pinned very low where you can, maybe round the bearers /
floor level and then pulling from that. I have a little Tirfor
'Jockey' wire rope winch (that could probably damage the shed if you
kept winching and it didn't move) ... as long as you can also get a
good anchorage in the right direction?

I think the biggest issue (without a crane) might be the consistency
of the ground.

p.s. I (still) have a 8'x6' taylor made wooden shed in my Mums back
garden, bought for me (to act as my own workshop) when I was about 16.

It's still pretty sound, all but the bearers it sits on and whilst
it's on nice flat concrete with at least 8' access at either end,
getting something underneath to take the load again wouldn't be easy.
In an idea world I'd roll it over onto it's face, remove the old
bearers and fit the new ones ...
