Extending a concrete base for a greenhouse

Good morning. I wondered if anyone could advise if my plan for altering a concrete base for a new greenhouse is a good one.
We have a 7' x 5' shed on a concrete base at present. The base is also 7' x 5'. The base is a raised part of a slightly sloping larger concrete hardstanding.
I want to expand the raised base section to accomodate an 8' x 6' greenhouse. My plan was to section off the new part with timber and coat the hardstanding with a good layer of PVA before laying concrete to extend the base at it's current level first.
However, because the hardstanding is slightly sloping I think I will need to slightly raise the height of the whole new base to allow for the extra foot of length. I was hoping to do this by using a self-levelling screed on top of the concrete. This should also remove any join between the new and existing base.
Any thoughts?

Forget the PVA it will do nothing.0

I haven't got a greenhouse, but I am sure that concrete floors are not normally recommended or used in green houses. As they are not thought to be necessary. Feel free to correct me if I am wrong.I can afford anything that I want.
Just so long as I don't want much.0 -

You're right. They aren't ideal because of drainage and certainly aren't necessary in all but the most windy spots. However, we're stuck with what we have because the existing hardstanding is there and I don't want to go digging it up.0 -
Another vote against PVA, I’d say you really need to get some sort of mechanical connection between the two sections.
On bigger jobs we’ve resorted to drilling holes and then resin fixing bits of rebar0
