About This Renovation

Renovating in NYC always presents challenges, but the Tribeca condo we fully renovated at 335 Greenwich St required a distinct transformation. Once an artist’s live-work studio, the open air space carried traces of past creativity: paint-splattered floors, an industrial layout, and a configuration that prioritized work over everyday living. When a newlywed couple purchased the corner loft, they set out to create a home that balanced contemporary sophistication with subtle nods to the building’s Art Deco heritage. Enter Gallery.

Our full-scale gut renovation redefined the apartment’s flow, replacing the original two-bedroom layout with a more functional three-bedroom design. The updated plan introduced 1.5 additional bathrooms, reconfigured living areas, and incorporated dropped ceilings to enhance lighting and proportion. Every design choice balances modern elegance with original architectural character, creating a refined home fit for any era.

Thoughtful Reconfiguration With Timeless Design

Reimagining this Tribeca loft involved creating a space that balances modern functionality with timeless style. The reconfigured design focused on maximizing usability, especially in the heart of the home: the kitchen and living areas. The thoughtful design embraces modern necessity while incorporating subtle Art Deco influences through brass fixtures, considerate lighting, and architectural accents.

A Kitchen & Living Space Designed For Entertaining

With soaring ceilings and an expansive Calacatta Black Marble Polished waterfall island, the kitchen was designed as the home’s centerpiece for both form and function. Installing the full stone island was no easy feat, requiring precise planning and a labor-intensive lift through the building’s elevator. The island is complemented by Amazing Silver marble on the kitchen countertops and backsplash, along with accent walls and shelving in the adjoining dining room. A black and brass sloped hood ties together the space’s sophistication, while the open layout welcomes guests and makes hosting easy, one of the couple’s top priorities in their renovation. Appliances include a Wolf GR366 range, a Wolf E Series speed oven, and a Sub-Zero refrigerator and wine fridge. 

Elevated Elegance In Both Bathrooms

The primary bath was designed as a serene retreat, which can be needed amidst the hustle and bustle of Manhattan. To accomplish the grounded look and feel, our design leaned into natural stone and Earth tones. The approach is anchored with a custom-crafted Calacatta Viola marble vanity, which we also repurposed to create a striking feature wall in the shower, positioned slightly forward to highlight the bold design. In another example of leveraging all materials at hand, we repurposed stone from the backsplash in the kitchen and dining room for built-in shower shelving within the architectural nooks. To add texture and contrast, we paired the richly veined marble with Porcelanosa Ice Minnesota tile for the walls and Austin Natural tile for the floor. Finally, the spacious shower offers dual Brizo Odin Thermostatic brass showerheads to enhance the spa-like experience.

The secondary bathroom delivers a more bold design, providing high-end comfort and elegance at a glance. The countertop stone is a light MSI Statuary Classique quartz, complimented starkly with Bedrosian Cloe Green ceramic wall tiles and extremely choice Prism Rosa Pink Polished Marble Mosaic flooring from Tilebar. The design is accentuated with a matching luxe gold faucet and shower system from Brizo’s Levoir collection.

Custom Office With Iron Doors

When you’re WFH, your office needs to be both welcoming and motivating. To deliver that delicate balance, we designed a sophisticated space meant to make the most of the lofty surroundings. Rather than completely separating the office from the expansive living area, we introduced iron interior doors, helping to soundproof the secluded room with a sense of style. The study iron door was based on inspiration images provided by the clients, which we then sourced a vendor to custom-build.

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!!
