GOING UP: Despite reports of Nike moving into New York’s SoHo, it seems as though the sneaker giant has yet to sign on the dotted line for a lease at 529 Broadway. The corner building on Spring Street was razed last week and a new 52,500-square-foot one will be constructed. The building is still available, according to a source familiar with the five-floor property, who requested anonymity. Café Bari, Steve Madden, Lush, Kiosk, Sabon and baked by Melissa were among the nearby tenants that had to heave-ho. The asking rate for ground-floor space in 529 Broadway is $1,200 per square foot, with the other floors going for considerably less. A Nike executive declined to comment. The arrival of Michael Kors’ mega-store nearby and the anticipation of spring are attracting more tire-kicking brands, one source said. Construction at 529 Broadway is expected to be completed by the end of this year.
