About Expert Designers

ADU Design and Legalization Services in NYC

Expert Designers is an ADU architect firm based in New York City, helping property owners convert underutilized spaces — such as garages, basements, and backyards — into legal accessory dwelling units. Their services cover the full process, from initial design through permit filing and construction support, with a focus on keeping projects compliant with NYC's regulations.

As an accessory dwelling unit builder operating in one of the country's most complex regulatory environments, Expert Designers works to simplify what can otherwise be a difficult and time-consuming process for homeowners. They handle design, legalization, and guidance through the city's evolving zoning and building rules.

The City of Yes and What It Means for ADU Projects

New York City's City of Yes initiative has introduced meaningful changes that affect how ADUs can be built and approved. Expert Designers keeps up with these regulatory shifts so their clients can take advantage of the updated framework.

  1. Simplified Conversion Rules: Converting basements or garages into legal living spaces has become more accessible under the new initiative, opening up options that were previously unavailable to many homeowners.
  2. Updated Zoning Restrictions: Zoning laws have been revised to support additional housing options, removing a number of the previous barriers that blocked garage conversion and other ADU projects.
  3. Streamlined Approval Process: The path to permits and approvals is now more straightforward, which can mean faster processing and fewer delays for property owners pursuing ADU development.

Expert Designers monitors changes in NYC zoning, Department of Buildings (DOB) rules, and housing initiatives on an ongoing basis. This allows them to ensure that each project is structured to meet current requirements and take advantage of available policies.

What Expert Designers Offers

Their process is structured to take a project from concept to a fully approved, legal unit. The key stages include:

  1. Consultation: They assess the property and evaluate zoning eligibility before any design work begins.
  2. Design: Custom ADU plans are developed to optimize the available space while meeting all applicable building codes.
  3. Permit Filing: Expert Designers manages all DOB paperwork and submissions, handling compliance requirements from start to finish.
  4. Construction Support: They provide guidance through the construction phase and assist with final inspections.

Building an ADU in NYC can offer several practical benefits for property owners. A legal granny flat, in-law suite, or detached ADU can generate rental income, increase the overall market value of a property, and provide flexible living arrangements for extended family or caregivers. It can also contribute to addressing the city's broader housing needs by making better use of existing residential lots.

Expert Designers positions itself as a resource for homeowners who want to navigate NYC's ADU regulations without having to manage the complexity on their own. Their scope covers architectural services, property legalization, and construction coordination — making them a single point of contact throughout the project lifecycle.

" Exceptional Architects, Builders, and Problem Solvers I had the pleasure of working with Bernardo Gamba and his team at Expert Designers, and I can say without hesitation that they are among the most knowledgeable, professional, and reliable firms Ive worked with in the architecture and construction space. Expert Designers is truly a full-service firm. From architectural drawings and design concepts to home builds, conversions, and the removal of violations, they understand the process from start to finishand more importantly, they know how to navigate real-world challenges that come up with municipalities, zoning, DOB, and compliance issues. Bernardo brings a rare combination of technical expertise, practical construction knowledge, and strategic thinking. He doesnt just draw planshe thinks through feasibility, cost efficiency, timelines, and approval pathways before putting anything on paper. That level of foresight saves time, money, and frustration. The team is highly responsive, detail-oriented, and professional. Communication was clear throughout the process, expectations were set properly, and deliverables were handled with precision. Whether its resolving violations, handling a conversion, or designing and building from the ground up, they approach every project with confidence and competence. In an industry where mistakes and delays can be extremely costly, Expert Designers stands out for doing things the right way. If you are a homeowner, investor, or developer looking for an architectural and building firm you can truly trust, I strongly recommend Bernardo Gamba and Expert Designers. Top-notch work, excellent service, and results you can rely on. Highly recommended."
