About This Renovation

When space gets tight and kids get older, proactive families think ahead. In this character-rich Chelsea condo—once the Krisiloff Bros Sewing Machine Co factory and now a boutique co-op tucked between Madison Square Park and the Chelsea Gallery District—our clients saw an opportunity to evolve. With two growing children and a 2-bedroom layout that no longer served them, they partnered with Gallery to reimagine their home’s flow, functionality, and style. The result? A striking 3-bedroom, 2-bath transformation that maximizes storage, celebrates the building’s industrial bones, and delivers the transitional-meets-contemporary aesthetic the family envisioned—all thanks to our collaborative full-service design-build process.

More Bedrooms, Less Friction

When you’ve got two young teenage children who share a bedroom, you’re walking on thin ice. That was one of the key catalysts for the renovation, pushing our clients to reconfigure their space in order to comfortably add an extra bedroom and give each child their own space. To make this happen, we created a third bedroom by framing within the existing open area, slightly reducing the common area footprint to make room for the new layout.

In the daughter’s room, we pushed the wall slightly toward the living room to expand her closet space, giving her the storage she needed without compromising flow. For the newly-framed son’s room, we added a seasonal storage compartment above the closet to maximize vertical storage. Meanwhile, the primary bedroom was reoriented to accommodate a true ensuite master bathroom and a walk-in closet—designed around a client-selected closet system, with our team guiding the layout for optimal function. Three bedrooms, two teens, one happy family.

A Second Bathroom To Match  

While adding the second bathroom was a huge help for their evolving family, there was still room to maximize the space further to accommodate growth. Enter—a full bathroom conversion. By splitting one large bathroom into two, we created a private ensuite for the parents and a secondary bath for the kids (or guests) that is accessible from the main living area. A strategic wall shift of about 10 inches gave us just enough wiggle room to fit a 34–36” vanity, standard toilet clearance, and a comfortable shower in each space.

To free up valuable square footage, we coordinated with the building to shift the original plumbing risers behind the walls, improving flow while preserving the overall aesthetic.In the primary ensuite, a Brizo Odin widespread faucet pairs with Bianco Dolomiti tile across the floor and walls, while a honed Arabescato D’Oro marble elevates the shower with subtle contrast—creating a serene but statement-making retreat for the parents.

Strategic Kitchen Layout With Built-In Storage Solutions

While the primary goal of this Chelsea condo renovation was to make the most of every square inch, the full gut remodel also created an opportunity to reimagine the kitchen. We introduced a new layout centered on functionality and flow, incorporating an appliance garage with pocket doors, two-tier cabinetry, a Magic Corner cabinet organizer, plus a mix of pull-outs and roll-outs to maximize storage. Open shelving balanced the space visually, while a concealed charging station kept surfaces free of clutter.

Cabinet finishes and materials were thoughtfully selected to complement the clients’ RH-inspired dining furniture — including a Neolith Calacatta Gold Silk surface that adds a refined, marble-like elegance with the durability needed for everyday use. Finally, alongside the new Sub-Zero refrigerator and Wolf GR366 range, we added a dual-zone Zephyr PRESRV wine cooler with capacity for 45 bottles — the perfect finishing touch for a kitchen designed to work hard, live comfortably, and always be ready to entertain. Salut.

Mission: Island Slab Installation

One significant challenge was installing the oversized Neolith Calacatta Gold Silk island slab, which was too large to fit in the building’s elevator. After extensive coordination and building approvals, we devised a solution that felt straight out of a Mission Impossible movie. We opened the elevator shaft on the second floor (while the elevator sat at the first), placed the slab on top of the elevator inside the shaft, then had contractors ride the elevator roof up to the fourth floor to safely receive and install—ensuring not a single detail was compromised. Tom Cruise could never. 

Thoughtful Space Optimization

In this renovation, tight spaces became opportunities. For example, a narrow gap between a structural column and wall was transformed into custom laundry storage, turning an awkward spot into a practical solution. Throughout the rest of the home, we focused on smart storage details and built-in features that support the family’s evolving needs—bringing thoughtful design to every corner without compromising the condo’s open, airy feel.

Additional Highlights

  • Full HVAC Solution: Installed full HVAC system with rooftop condensers, floor-routed ductwork, and extensive coordination between HVAC team, electricians, and building management
  • Old Doors, New Purpose: Repurposed original walnut doors (including bathroom pocket doors and closet doors) for use in new bathrooms, the pantry, and entry closet, requiring precise framing adjustments
  • Flooring Update: Replaced flooring throughout the apartment

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!!
