In true New York fashion people make the best of what they have, while always striving for more. Well this apartment come mansion in TriBeCa fits that m.o. to the tee. As we all know there isn't much room left on the island so you've got to work with what is available - enter 144 Duane Street. This 1862 limestone building has been converted into a modern 25,000 square foot palace with a price tag just under $50 million. Complete with private gym, roof terrace and as many skylights to watch the stars through as possible, this mega townhouse's furnishings are a little to be admired, however the bones are there for sure. Any takers?
