Brooklyn Heights Pre-War Co-Op Combination | 61 Pierrepont

Gallery KBNY's eight-month design-build combination of a 1,350-square-foot pre-war co-op at 61 Pierrepont in Brooklyn Heights

About This Renovation

When our clients welcomed their first baby, they saw an opportunity to create a more family-focused home without leaving their beloved Brooklyn Heights neighborhood. Having lived in the area for years, they valued the schools and community but needed more space. Instead of a full gut renovation, they chose to preserve the pre-war charm of their two-bedroom unit in their landmarked building at 61 Pierrepont, including original floors and the kitchen, while formally combining the space with a neighboring unit. Our team renovated all the bathrooms, added new wall moldings, updated the lighting, and installed HVAC, blending modern functionality with timeless details to turn their tight and dated apartment into a warm, family-friendly home.

Sayonara, Studio

The transformation of the integrated space was dramatic, with a former studio apartment completely absorbed into the original two-bedroom apartment design, then reconfigured beyond recognition. The studio was reimagined as a spacious master bedroom and en suite bathroom, blending effortlessly with the layout of the original unit to form a cohesive and functional space tailored to our client’s expanding needs. The design for the reimagined co-op carries a traditional style with ornamental wall mouldings, timeless lighting, and traditional door accents, enhancing the original detail and offering a true to pre-war look. 

Master Bathroom Pivot 

With such adjusted floorplans, the master bathroom underwent a complete transformation, as the space was originally the kitchen and bathroom of the adjoining small studio. From outset, the client’s plan was to purchase part of the exterior hallway, in order to enlarge the space exactly the way they envisioned. However, when that plan was unable to be executed mid-way through the process, we had to pivot and adjust design plans significantly. Reconfiguring the space spontaneously required careful planning to maximize functionality amidst the abbreviated square footage, while addressing subsequent structural challenges. 

Updated HVAC? A Must

In combining two condos, one of the necessities required was enhanced heating and cooling. To accommodate, we created a custom central air solution more appropriate for the freshly enlarged space, without sacrificing any of the original historic details garnishing our clients’ charming pre-war home.

What Can I Expect In Regard To My Project's Final Cost?

Renovation costs vary significantly based on apartment size, scope, finish level, existing conditions, and building type. As a general benchmark in Manhattan:

  • Full gut renovation, pre-war apartment (~1,800 sq ft), upper-mid-level finishes: $500 to $650 per sq ft, or approximately $850,000 to $1,000,000+
  • Same scope with luxury finishes, elaborate millwork, and extensive HVAC or window work: $600 to $850 per sq ft, or $1,000,000 to $1,500,000+
  • Newer building in good condition, primarily cosmetic renovation: $375 to $500 per sq ft, or approximately $650,000 to $900,000

Pre-war buildings typically cost more due to older infrastructure and additional labor requirements.

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!!
