This gorgeous Al Beadle condominium high-rise was already a midtown standout before its owners ponied up for an exterior renovation. Now, Executive Towers looks as good as (if not better than) it did when it threw open its shiny glass doors in 1964. Newly repainted stairwells sparkle in stunning turquoise, offset by balconies of palest lemon yellow. Neatly redesigned landscaping and a rejuvenated concrete lagoon surrounding Beadle's "floating" structural design add to the appeal of this popular landmark, which recently earned both national and local historic designations. Interior tweaks include grey-and-turquoise walls and carpeting on each floor. Anyone jonesing to live in a gorgeous and period-correct midcentury building might line up for one of Executive Towers' sought-after condos.
