Manhattan, New York
Built-in bookcases in Manhattan.
Designed online with a live 3D view and price, measured in your home, then built and installed by the Kloset Worx studio.

Most Manhattan projects happen inside one of three kinds of building. Prewar co-ops, from the Upper West Side to Carnegie Hill, have plaster walls, generous ceilings and walls that are rarely as straight as the floor plan suggests. Downtown lofts in Tribeca, SoHo and NoHo bring high ceilings, exposed brick and floors that can drift an inch or more across a room. Newer condos, from Hudson Yards to the Financial District, have flat drywall, tight dimensions and strict building rules.
Each one changes how built-ins are measured, anchored and delivered. That is why every Worx design is confirmed at a site measure before anything is drawn for the shop.
Built-in bookcases in Manhattan rooms
Prewar Manhattan living rooms and libraries were often built with shelving in mind: tall ceilings, deep window casings and a fireplace on the long wall. A built-in library that returns to the casings and frames the mantel can look original to the apartment.
In newer apartments, where walls are flat and ceilings lower, a library wall works best as one long run with closed base cabinets and lighting under every shelf. It gives a modern room some warmth and depth.
Alteration agreements and board approval
Most co-ops and many condos ask for an alteration agreement before work starts, and some send drawings to the building's architect. Built-in millwork with no plumbing, gas or structural work is usually a simple approval, but it still takes time. Start the paperwork when you sign the drawings, not the week before install.
Insurance certificates
Managing agents almost always ask for certificates of insurance naming the building, the managing agent and sometimes the board. Send us your building's COI requirements early so they are settled before install day.
Freight elevators and work hours
Install days are booked around the freight elevator and the house rules, which usually limit work to weekday business hours. Larger pieces are built in sections sized for the elevator cab and the corridor turns, then joined in the apartment.
Plaster and out-of-square walls
Prewar walls bow and corners drift. Built-ins are scribed to the wall with filler strips and scribe moldings, so the finished piece looks straight even when the room is not.

Can built-ins go around a prewar fireplace?
Yes. The shelving returns to the mantel and the wall above can be paneled to match.
Will the building need to approve bookshelves?
Many co-ops want drawings and an insurance certificate even for millwork. It's usually a simple approval.
Is the design visit free?
Yes. Book a free design visit, or start in the online designer and send your design to the studio.
How long does it take?
About 4 — 5 weeks from signed drawings. Installation is usually one to three days.
