"No expense spared" is never really an accurate thing to say. If a home actually existed where zero expenses had been spared during its construction, it would be made out of solid gold and have a moat. You don't see very many solid gold houses, and it's not because everybody doesn't love gold. It's because gold is a pretty significant expense and you usually have to spare it (also it's very soft and would be a terrible thing to build a house out of but don't worry about that.) One doesn't usually have to spare the expense of, say, installing kitchen appliances, though.
Look, this isn't to say that vertical strips of brick and huge metal ventilation pipes aren't expensive. Actually, in this case, perhaps a few expenses could have been spared.
Now this is what's happening. In a true "No Expense Spared" house, every single carve-able item in the place would be shaped into a statue of a dude doing some weird pose. Shower rods, door knobs, everything. This house seems to only have this one little guy, but it's a start.
