The short answer is "yes" if the existing base is flat or very slightly sloping, at least 4" thick and hasn't cracked up.
Ragnar's suggestion would certainly work, but given the current cost of timber will almost certainly cost more and require some skills.
As a general point, tanalised timber ceased to exist years ago, the process was more than slightly toxic but had the benefit of working. What we get now is pressure treated, which rarely penetrates far into the timber and consequently doesn't work as well. Always treat the end grain of any timber of this type.

Thank you for that - I didn’t know. I though ‘pressure treated’ was the current word for ‘tantalised’. Every day is a school day.
(Edit) I went off to educate myself further and found;

Now I’m confused. If you have time (since you are presumably in the trade) could you explain further - perhaps it was different carrier chemicals?

Thanks for the advice!

@ColinTheBald Could you pour concrete around the old base and incorporate it into the new one or is that just a recipe for disaster? (Asking for myself for when I install a bigger shed.)
