CooperBuild

CooperBuild operates as a general contractor in New York City, coordinating projects like kitchen and bath renovations, flooring replacements, and custom carpentry. Two flights above Fifth Avenue, the office sits at 276 5th Ave Ste 704 PMB 170, one block south of the Morgan Library. Scope ranges from structural changes to cosmetic upgrades, each handled under a single contract—no subcontractor roulette.

Beyond the usual remodel trade, they assist with permit applications and punch-list walk-throughs, keeping paperwork from burying the build. Interior door installations, shelving units, and built-in cabinetry are staples they return to often. Tenants in pre-war co-ops and owners of brownstone top-offs both end up here once the architect’s drawings land on the desk.

Call or text the job site line (631) 213-1170 for an on-site visit; the team prefers a tape measure over a sales pitch. A quick click to the map pins the exact entrance on Fifth Avenue—no maze of basements or freight elevators once you’re inside the lobby. That’s the fastest way to find the right door.
