That's not even close to pushing the boundaries for a new house. Your tank has a huge footprint for its volume.

The interweb tells me a standard bathtub holds about 60 gals. Ergo, your 180 gallon is comparable to 3 standard tubs stacked on top of each other. Slightly different footprint, yes, but something to consider as a reference.

Invite 10 of your buddies over for beer and wings, stand them all in the spot where the tank is going while bouncing up and down. Pretty simple.
