When imagining a place, not a specific place that I want to visit, which is more appropriate to use:
- ( high as much it could be )
or
- ( high as much it can be )

Use "as high as could be" not "high as much it {could/can} be".
As you stated, this is something that does not exist. You don't know that it "can" be that high. But you wish that it "could" be. So you use "could" for the hypothetical (not real) thing.
Neither. You don't need 'as much.'
The bird's nest was as high as it could be. (For your sentence it sounds like this is what you are going for) The bird's nest was much higher than I could reach with a ladder.
'As much high' is simply incorrect.
