Imagine walking through New York City in the 1920s. What was different? Well, cars rolled around on what looked like bike tires, women had just received the right to vote, prohibition was in effect, and it was notably harder to find a decent wi-fi signal. But while the Manhattan skyline was notably lower during the Coolidge Administration, the brick and limestone apartment buildings -- today's sought-after pre-war apartment buildings -- were then, and still are, high-style standouts. Which perhaps has something to do with why so many new construction Manhattan condominiums are opting for a look that hearkens back to Manhattan's architectural heyday. Yes, today's classic-style luxury condominiums tend offer all kinds of modern conveniences and luxuries -- the LEED-certified 456 West 19th Street, for instance, pairs classic lines with floor-to-ceiling windows. When it comes to Manhattan condominium aesthetics, though, everything old is seemingly new again.
