About This Renovation

Our clients purchased a condominium on the Upper East Side intent on a complete condo renovation before moving in. A post-war space, the bones had already been modernized but the overall vibe was outdated. The kitchen was not functional and the home lacked storage. On top of that, the original darker color palette failed to take advantage of the condo’s ample natural light.

A Contemporary Look

While the overall aesthetic is decidedly contemporary, the updated kitchen and dining room from this Upper East Side, Manhattan condo renovation best epitomize the clean, sleek lines of this style. Flat-panel high-gloss upper cabinets in white are the height of contemporary, with lower cabinets featuring a light, sandy finish for neutral contrast. Self-closing drawers further the focus on the modern look of this condo kitchen remodel, as well as the subtly elegant Cambria natural quartz countertops and matching porcelain floor tiles.

The kitchen’s natural footprint is so small that we optimized storage by adding a whole wall of glossy white cabinets in the dining room, with a wine cooler tucked into one of the sides as well. The perfectly smooth surface of the glossy white lacquered cabinets makes the most of the expansive natural light in the dining room, naturally making the space feel larger.

Notes on the Bathrooms

We carried the contemporary spirit into the three bathrooms remodeled in this Manhattan condo renovation.

In the master bathroom, we cultivated a spa-like atmosphere with floor-to-ceiling Carrara marble.

In the kid’s bathroom, glossy ceramic tiles are accented with a mosaic-style shower niche, while the oak vanity softens the room.

The third bathroom, a rare powder room with a shower, features Carrara marble floor tiles with a mosaic accent wall and brushed walnut vanity, with dark gray floor tiles in the shower for a contrasting touch.


Some Highlights

  • Built-in cabinetry in the living room for additional multi-purpose storage
  • New select oak wheat flooring throughout
  • Sputnik chandelier in the dining room
  • Extra wall of glossy white cabinets for additional kitchen storage
  • Floor-to-ceiling Carrara marble in the master bath

NYC RENOVATION FAQS

How Long Does A Full Apartment Renovation Take?

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.

How Long Does A Kitchen Renovation Take?

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.

How Long Does A Bathroom Renovation Take?

The construction portion of a bathroom renovation typically takes three to four weeks. Gallery KBNY renovates bathrooms as part of larger interior renovations, so bathroom work is sequenced alongside the rest of the apartment within the overall project schedule.

How Long Does Co-Op Board Approval Take?

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.

Our success stories

Forget about any horror story you have heard about contractors. Stop right here. This is the design-build contractor you want to HIRE. It was a breeze working with Gallery on our apartment combination project. We looked at quiet a few design-build companies and chose Gallery because of the great communication and the fact that they were able to manage material purchasing and product selection for us. They were honest, took responsibility and pride in their work.”

Gallery KBNY has been absolutely amazing with my renovation. As a complete newbie, I was expecting a stressful process, but they made everything incredibly smooth—and I learned so much along the way. They’re truly a concierge-level service that genuinely cares about both their clients and the quality of their work. I know I couldn’t have chosen a better team. Colin, Morgan, and Leo were fantastic with logistics; Kate is a brilliant designer; and Alex was, hands down, one of the most responsive and professional contacts I’ve ever worked with. The entire experience was marked by ease, efficiency, quality, and grace. 10/10 recommend!

We used Gallery KBNY to re-design our kitchen and other rooms. Avi Zikry's design was amazing. His vision enabled us to create a whole new look and a better functioning space. That was a year ago, and we are very happy with the results. I highly recommend him. View full renovation: https://www.gallerykbny.com/our-work/manhattan-apartment-renovation-91-central-park-west

We loved working with Avi and the whole team at Gallery Kitchen and Bath. From our very first meeting, we felt like we were in great hands. Avi is so responsive—always available, quick to come up with solutions, and he and his team helped us pivot whenever needed without losing momentum. Renovating in NYC is complicated, but they handled all the logistics seamlessly and made the process so much less stressful. They do everything—design, architectural work, and managing every detail and skilled trade needed for a full gut renovation of our loft apartment —so we never had to worry. They are in full control of their workers, which allows them to stay on track and adapt quickly. They were creative and helpful when we needed to pivot on design unexpectedly. We felt like we had true partners that genuinely cared about our project and our well being! The finished space truly exceeds our expectations—we are so proud of our beautiful new home. It’s hard to put into words how positive our experience was overall. We would not hesitate for a moment to recommend Avi and the entire team at Gallery. They will be our very first call if we ever need to renovate again in the future… and you should call right now if you’re considering a renovation!

I enthusiastically recommend Gallery, who did a superb job renovating our once decrepit 2-bedroom apartment in Brooklyn Heights. The project involved a full kitchen and bathroom renovation, as well as new electrical, refinished floors, new doors, new baseboards, and some rearranged bedroom closets. What is more, when I have them the wrong paint color for my daughter’s bedroom, and the team started to paint that color, they got the paint I wanted and corrected the “mistake” (which has actually been my mistake) and didn’t charge me for that either. I’d choose them again 100 times over and definitely recommend them to anyone considering a similar project.

We interviewed about 8 different companies before hiring a contractor for our apartment renovations. Although Gallery was not the cheapest option, we chose them based on their upfront billing format, high client reviews, and depth of knowledge. We loved how it was a “one stop shop” and were paying one bill, up front. Everything was very transparent and we could not be happier with the results! Our apartment looks exactly how we imagined. Thank you!!
