Custom built-in storage in NYC.

New York gives storage a difficult brief: make more room without making the apartment feel smaller. A freestanding cabinet gives up the inches above it, beside it and behind it. A fitted built-in can use the wall from floor to ceiling, return cleanly into an alcove, work around moulding and radiators, and make storage feel like part of the architecture.

Kloset Worx surveys the actual room, develops the layout in 3D, mills the cabinetry to those dimensions in the Bronx, and installs it with the same team that built it. That matters in prewar apartments with walls that are not perfectly plumb, brownstones with original trim worth preserving, and newer condos where a few inches can decide whether the room feels open or crowded.

The goal is not simply more shelves. It is to decide what belongs behind a door, what should stay visible, what needs to be reached every day, and what can move higher. The finished built-in should make the room quieter as well as more useful.

The wall is rarely as simple as it looks.

NYC apartments can combine plaster, drywall, masonry, uneven floors, deep baseboards, old radiators, window returns and building rules in the same room. A fitted installation has to account for those conditions before fabrication. We measure the room in person and resolve the junctions in the drawings rather than trimming a standard system on site.

For co-ops and condos, installation planning also means working around building access, certificates of insurance and freight-elevator schedules. For brownstones and townhouses, the challenge is often different: keeping original trim and proportions intact while adding storage that feels as though it belongs there.
