A multi-million-dollar home means different things in different places — but in New York, it's a six-storey townhouse spanning more than 9,000 square feet.

According to the listing, this "modern mansion" in Chelsea was built in 1920, but whatever period influences the property once featured appear to have been entirely replaced by sleek interior design and modern fixtures.

In addition to a kitchen kitted-out with Gaggenau appliances and a glass-encased garage large enough to accommodate an SUV, the home also boasts a "floating glass pavilion," a wet bar and, of course, an elevator. Why use your legs to travel around your giant house when a machine can do the work for you?

There are four sizable bedrooms across the six floors, and a whopping nine bathrooms — including one with a sauna and steam shower.

As if the secluded "subterranean garden" on the home's entertaining level isn't enough, there's also a rooftop terrace offering unobstructed views of the south, west and north of the city. What more could you want from a $17.5 million house?
