If the observer is at 800-850 feet, with an intervening hill between him and the target buildings of 650 feet, and we know the distance between them, then simple school-level trig will tell us the downward angle from observer to intervening hill, and by extension from that, the height H at which that sightline should meet the buildings - IF the underlying plane and reference level for all the heights is perfectly flat.

Like this;



Storm, I invite you do the calcs for us ...

Not Flat. Happy to prove this, if you ask me.

Nearly all flat earthers agree the earth is not a globe.

Nearly?

Yet, in the southern U.S., Venus is visible at 45 degrees -- WAY up in the night sky, after sundown for at least two months STRAIGHT. Tonight, Venus is visible for as long FOUR HOURS after sunset. That means I can see it til ONE O'CLOCK in the morning.
Can you tell us what latitude you are at in the mid-northern latitudes, and what time sunset is for that particular latitude in March on a particular day that you claim to see Venus at 1am?
