The talk of the week in the NYC real estate circles: Demi Moore put her triplex, located on the top of the south tower of the famed San Remo building for sale. And yes, it is a big deal. Because the San Remo, designed by Emery Roth and constructed in 1929, is not only one of NYC’s most magnificent residential buildings, but also an architectural symbol of Central Park West and of the time it was built, on the verge of the Great Depression. I know how spacious, grand, and elegant are all of its apartments, because the San Remo used to be my own home. What I mostly enjoyed about these news is the surfacing of the old black and white photos of this same apartment, in the collection of the Museum of the City of New York, dating 1937, when it was this penthouse was the home of Theodore C. Wiehe (1880-1973).
