Castle 5 Studios

Stone yards rarely make it onto Madison Avenue, yet here one sits between the glass towers. Castle 5 Studios supplies slabs of marble, granite, quartzite, and limestone to architects and homeowners who need more than a big-box sample. They cut to measure and can source book-matched pairs or entire container loads, so the material arrives ready for site. A visit starts at 286 Madison Ave New York, NY 10017; the address places them a short walk from Grand Central, where the same stone once clad the terminal itself. Questions about lead time or finish can be answered at (212) 433-3232. For directions, the map is at this link; the sidewalk outside still carries the faint polish of yesterday’s deliveries.
