Darius Design Build

Around 350 5th Ave sits a name craftspeople in the city keep tucked in their Rolodexes. Darius Design Build, the general contractor, holds down the 23rd floor in the tower whose chiseled limestone turns pink after four. Concrete-chokers and superintendent hats have used the address for decades, trading punch-lists in the marble lobby before the elevators whisk everyone skyward. From gut renovations to high-end build-outs, the outfit shuffles permits, schedules trades, and signs off on blueprint tweaks without missing a milestone. They’ll spearhead full-floor gut-renovations in FiDi high-rises, splice MEP shafts through landmark façades, and hand back the keys once the punch-list looks like a curbed overrun. If the survey datum shifts or the DOB red-tags a riser, they’re the crew that marshals the swarm of inspectors before the calendar flips. Use the map below for the exact walk from Penn Station—350 5th Avenue is a ten-minute sprint past Macy’s fluorescent window boxes and Koreatown’s fire-escape herb gardens.
