Question Observatory on top of a concrete water tank?

Please don't laugh!

After several years waiting, my wife and I are about to build a new home on a block of land we own. Unlike where we are now, this site will be more observatory friendly (even more so if some "northern die-back" occurred! ).

My father-in-law (an architect) is currently preparing designs for the house. He is even willing to consider doing the observatory. But...

He is talking about placing the observatory (type yet to be determined) on top of a large concrete water tank.

When I talked about problems of vibration, separating the pier from the surrounding concrete etc, he seems to think that this can be solved with enough concrete (my words, not his).

So the question is: can a pier that is attached to a large concrete water tank be used as an acceptable platform, or is vibration going to kill me? And yes, I'd like to do some imaging!

Opinions, informed or otherwise, are welcome!
