Our recent renovation at 1035 5th Avenue found us in the middle of quintessential Manhattan. Overlooking Central Park, this beautiful Italian Renaissance Palazzo co-op is located on Fifth and 85th street, just down the street from The Met. When our client purchased this 4,000 square foot pre-war property, the space hadn’t been updated in more than 50 years. The vision for this renovation called for a complete design overhaul of the extensive space, while incorporating many of the prior architectural elements and elegant marble accents, while also creating an additional bathroom and powder room. While the results speak for themselves, the client’s glowing praise for our full-service approach went a long way.
Typically, when fully renovating a pre-war apartment in NYC, the job often welcomes a gut renovation, in order to fully customize and modernize the dated space as needed. However, in the case of this 4,000 square foot historic home, the architectural accents and original marble offer one-of-a-kind design opportunities that add and maintain value, so a full gut renovation was out of the question.
For us, the biggest challenge became protecting those distinguished details, while also blending into new additions so the final look was cohesive. That fine touch required an immense amount of customization and specific trims to match existing, along with floor restoration in the majority of the home that included stitching to large portions of the original parquet flooring to ensure proper blend. We also rewired 60% of the property, which required strategic openings to ensure nothing of pre-war significance was altered. To honor the marble accents throughout the space, we polished every surface and matched certain epoxies when required to get as close as possible to the original look and feel.


To match the foundational pre-war details, our transitional design plan called for accentuating the millwork throughout the space. The focal point of this immaculate woodwork is the library, which features wall to wall white oak shelving and paneled millwork throughout the entire space. Focal point features in the kitchen and family room exhibit extensive millwork upgrades as well, as do the bedrooms. The kids room features a custom white oak bunk-bed that is built floor-to-ceiling with steps on the side for easy and safe access.
Another significant challenge when renovating this pre-war co-op was creating central air in the space without having to drop ceilings that would impact the period aesthetics, or more importantly block any of the Central Park views. Our solution was a true split HVAC called a VRV system, which we placed in the back laundry room. This required us to turn the space into a formal indoor/outdoor room that allowed the condenser to have circulation of fresh air from outside while still being well-insulated by residing inside. To do this, we removed a window and created an automatic louver that opens and closes accordingly as the VRV system cycles on and off. The room is also equipped with a drainage system so any water managing to trickle inside immediately gets drained. Finally, we ran heat trace lines on all the plumbing pipes so they’ll never freeze, as a secondary measure beyond insulation.

For a full apartment of about 1,700 square feet, construction typically runs five to six months. Design, board approval, and permitting come first and usually take four to six months, so most full renovations move from first consultation to move-in in 10 to 12 months. Scope, building rules, and how much infrastructure is being replaced set where a project falls in that range.

The construction portion of a full kitchen renovation typically takes 7 to 11 weeks. Door to door, the timeline depends mostly on the building: about 10 to 14 weeks in a private townhouse, 14 to 20 weeks in a condo, 16 to 24 weeks in a post-war co-op, and 20 to 30 weeks in a pre-war co-op, where board and engineering review take longer. Gallery KBNY orders custom cabinetry, stone, and long-lead appliances during design and approvals, so materials arrive ready for the build.

Board review and execution of the alteration agreement typically take 6 to 10 weeks in a post-war co-op and 8 to 14 weeks in a pre-war co-op, where asbestos filings, electrical load letters, and engineering review add steps. DOB permits usually run at the same time. A complete package with full technical drawings and specifications tends to clear the building's reviewing architect in one or two rounds, which keeps the approval phase on schedule.
