the.com/false front

means A structure or face built to look like a complete, substantial building when what's actually behind it is shallow or unfinished.

from The phrase comes straight from frontier-town architecture of the American West, where merchants nailed tall, flat, squared-off facades onto the fronts of simple one-story wooden shacks. From the street, the building looked like a proper two-story brick establishment; from the side or back, you'd see the thin wooden screen propped up with little behind it. The term later generalized into any deceptive front — political, corporate, or personal — that performs solidity it doesn't possess.
