What Our Clients Say
We worked with Lior from Prestige Custom from the initial design to construction/completion stage. In every way he exceeded our expectations! His attention to detail, eye for design, and meticulous approach to everything made us feel at ease throughout the process. He is a true professional and we trusted his judgement the entire time. Carolina in his office is amazing! She is on top of everything and is responsive and reliable for coordination questions. Lior's workers, team leaders and subs were remarkable. We were in incredible hands throughout the process with Lior and his team and now have our dream home to enjoy for many years!
Lior built our dream home and exceeded expectations, he was available basically all the time, which was huge for us from previous experience. Great eye for detail, solid communication, and all his contractors were professional. The whole process felt personal rather than transactional. Couldn't be happier with how everything turned out. Highly recommend Prestige!
I had the pleasure of working with Prestige Custom Builders on a design and build project in Sea Cliff, NY. From the very beginning, it was clear that this team was a true partner in every sense. They listened to my ideas and vision for the project and provided valuable input and guidance throughout the entire process. The team at Prestige Custom Builders was professional, responsive, and always willing to go above and beyond to ensure that the project was a success. They were also very transparent with their pricing and kept me informed of any changes or updates along the way. One of the things that really stood out to me was the quality of their work. They took great care in every aspect of the build, from the foundation to the finishes, and the end result was a beautiful new home that exceeded my expectations. Overall, my experience working with Prestige Custom Builders was exceptional. I would highly recommend them to anyone looking for a reliable and trustworthy general contractor. They truly are a pleasure to work with and I am grateful for the opportunity to have partnered with them on this project.
Leo built our Long Island home last year and made the whole thing surprisingly smooth. He's detail-oriented without being annoying about it, communicates well, and the team’s craftsmanship is top-notch. He had our back through the entire process. The finished product speaks for itself…beautiful work. Worth every penny…
We hired Prestige to Design/Build a new home for us in Great Neck. Prestige helped us with the exterior and interior design, they gave us new ideas, and suggested layout concepts that we used on our final plans. Prestige was with us every step of the way and made sure that our project was completed in a timely manner and on budget. Lior went to various stores with us and helped us pick out all of the design materials, such as tiles, fixtures and hardware. He made suggestions that made sense and helped us with the difficult decision making process. Prestige used project management software that was incredibly helpful. We received daily notifications with photos, videos and a brief description of what was accomplished. There was a full accounting and a construction schedule that we could easily follow. This put our minds at ease as we could see what was happening every day and track the progress of the work. Prestige was extremely professional and organized. We love our house and the level of detail throughout. I definitely recommend working with Prestige and Lior. Great home building experience.
We just finished building with Lior and couldn't be happier. He took care of everything from design, permits, construction so we didn't have to juggle multiple people. The build quality is excellent and all his subs did solid work. He was always available when we had questions and actually seemed to care about getting things right. Our house came out better than we imagined. Would definitely recommend.
Led Personally by Leo Golan
30 years. 100+ Long Island homes. One builder on every project.
"I don't bite more than I can chew. When I commit to your project, you get me — on site, on design, on every decision. That's why we only take on a handful of projects each year."
Leo founded Prestige on a simple conviction: the architect, the designer, and the builder should never be three separate conversations. Since 1992, he's built and renovated over 100 luxury homes across Long Island — from Kings Point to the Hamptons — and he's been personally in the room for every single one.
He still sits in every design session. He still walks every site. He still draws the elevations himself. When you hire Prestige, you get Leo — not an account manager, not a junior project lead, not a subcontractor chain.

The Questions We Get on Every First Call
Cost. Timeline. Renovate or build new. These are the conversations we have on every consultation — and we'd rather you have the answers before you book one.
What does a project actually cost?
The honest answer: it depends on your finishes. Roughly 40–45% of the total budget is elective—appliances, cabinetry, tile, countertops, and flooring. The same home can vary significantly depending on selections. As an example, an appliance package might range from ~$38K for Monogram appliances to $70K+ for Sub-Zero / Wolf—for the same house.
Typical investment ranges:
• New construction (Long Island): from the low $400s to low $500s per sq. ft. (higher for fully bespoke, high-end homes)
• Gut renovations: from the low $200s to high $300s per sq. ft. (high-end finishes at the upper end)
• Extensions & additions: generally align with new construction pricing, from the low $400s to low $500s per sq. ft.
• Architecture fees: $40K–$85K
• Interior design + 3D photorealistic renderings: $40K–$70K
We believe in setting clear expectations from the start. Every project is thoughtfully designed with your budget in mind—never in a financial vacuum.
Should I renovate or build new?
It’s one of the first conversations we have with nearly every homeowner—and the answer depends on the condition of your home.
When a property requires significant work, a gut renovation with an addition often comes within 10–20% of the cost of new construction. At that point, building new can offer greater long-term value: higher ceiling heights, more efficient layouts, and the ability to avoid unforeseen conditions behind existing walls.
Renovations, while often appealing, can introduce uncertainty—costs may evolve as conditions are uncovered during construction.
We design and build both. Our role is to guide you toward the option that best aligns with your property, your investment, and your long-term goals—with complete transparency from the start.
Where do you work—and who are you a good fit for?
We serve clients across Long Island—from Kings Point and Roslyn through Syosset, Jericho, and Huntington, down to Rockville Centre and east to the Hamptons.
We’re best suited for:
• Custom new construction projects starting at $1.5M
• Renovations starting at $500K
• Homeowners planning a 12–24 month timeline
• Clients seeking a fully integrated design-build experience
We’re not the right fit for:
• Projects under $500K
• Spec or flip work
• Compressed timelines under three months
Our work is intentionally focused—approximately 80% new construction and 20% major renovations. We limit the number of projects we take on so that every client receives dedicated attention from start to finish.
What happens during the design process—will I see my home before it’s built?
Yes—and it’s one of the main reasons clients choose us.
We design your home in fully immersive, photorealistic 3D. You can walk through each space, compare material palettes in real time, and experience key moments—your kitchen, primary suite, even the view to your future pool—before construction begins.
Beyond visualization, every selection within the model is tied to real products and current supplier pricing. Once design is finalized, that same model becomes your detailed, line-item build cost—giving you clarity on your investment before we ever break ground.
How long does a project take from start to finish?
Timelines vary by scope, but a typical project follows this structure:
• Architecture & design: 2–3 months
• Permitting: 2–3 months (longer if revisions are required)
• Construction:
• 12–14 months for homes up to ~4,000 sq. ft.
• 15–18 months for larger custom homes
From initial consultation to move-in, most projects are completed within 15–20 months.
Two things set our process apart: we build year-round, and we use the permitting phase to fully finalize all selections. By the time construction begins, every detail is resolved—eliminating delays and maintaining momentum.
How do you price your work—and why not lump sum?
We don’t use lump-sum pricing. Our clients deserve complete transparency.
Instead, we operate on a clear, standalone project management fee, and build your budget collaboratively—trade by trade, finish by finish—using real numbers from our vetted partners.
Because we integrate architecture and construction under one roof, design and budget evolve together. The result is a fully aligned project—where what you see, select, and approve is what you can confidently build.
It’s a more transparent approach, designed to eliminate surprises and ensure your investment is understood from the very beginning.
