About This Renovation

This stand-out Manhattan renovation began with a clear vision from our clients, a retired couple ready to settle into city life after years of managing a large vacation home in Provincetown. They wanted their new Sutton Place space to reflect their thoughtful traditional style while incorporating choice updates to make the most of the square footage. Collaborative from the outset, they were deeply involved in the design process, from selecting fixtures to refining layouts - but always welcomed our input throughout. Best case scenario. Together, we transformed their new abode into a home that feels timeless, functional, and entirely their own.

Full Gut Renovation, Everything Goes

We opened up the kitchen to create a more functional and inviting space while keeping the bathroom’s original footprint but upgrading it with all-new fixtures and finishes. Replacing the windows was a significant task, as was adding HVAC—a process made smoother thanks to the building’s incredibly supportive super. Despite the scope of the renovation, challenges were minimal, allowing us to approach the project with ease and execute the remodel on our own terms.

Every Room Is A Knockout 

Choosing a standout room in this home isn’t easy, as every space exudes its own unique charm. The clients, passionate about wallpaper, allowed us to bring creative design into each bathroom with carefully selected patterns that set the tone for each. The powder room features a moody wallpaper, adding a touch of drama, while the master bathroom embraces airy elegance with a light, refined design.  

Traditional Meets Contemporary

From a design stand point, the goal was traditional design with contemporary details. They have traditional style furniture, so they wanted that to reflect in the design. We accomplished this added millwork and wall accents throughout the space. Doors make an impact as well, with a few painted black—an uncommon request that added striking depth and dimension to the overall design.

Millwork Detail Throughout 

The millwork throughout this home was crafted with meticulous attention to detail, enhancing both the functionality and aesthetic of each space. In a unique niche of the entry hallway, we created a built-in bookcase that adds both function and charm. The den also features a custom-built bookcase, while the kitchen boasts a custom-built bar that enhances its beauty. The kitchen itself is stunning, with a luxurious marble countertop featuring a waterfall detail. One challenge we faced was a gas pipe running through the center of the island, which we couldn’t remove. Instead, we designed custom cabinetry around it, transforming the pipe into a seamless, architectural column.

Elevator Landing Update

To transform the entryway between the apartment and its neighbor, we updated the flooring with a sleek, modern finish and replaced the tile for a more cohesive look. The walls were adorned with a statement wallpaper that added texture and character, while a new light fixture set the perfect ambiance. These changes were designed to create an inviting, seamless transition as soon as you step off the elevator.

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!!
