It is too soon to say how long it will take New York to bounce back from the coronavirus pandemic, or what long-term effect the economic fallout will have on the real estate market. What we do know, though, is that many buildings that have been planned and under construction for years are now nearing the finish line. We take a look at the most highly anticipated new developments that have launched sales or are about to do so. The Benson is the first new condominium to take shape on a co-op-heavy section of Madison Avenue in over 20 years and will feature a design and limestone facade that pays tribute to prewar Upper East Side architecture. Three penthouses will come with secluded terraces, and all units will have interiors by Peter Pennoyer Architects, private elevator landing, oversized windows, soaring ceilings, custom crown moldings, fireplaces with custom mantles, custom kitchens by Christopher Peacock, and master suites that occupy their own wing. The building will offer 24-hour doorman and concierge service as well as a state of- the-art fitness center; half basketball court; spa with sauna and steam room; library with adjoining garden; art studio; pet spa with washing station; private cinema room; and landscaped roof lounge with fire pit and Central Park views.
