Testimonials

Marcelo was my architect for my urgent care center in Bellerose, NY, and I have had the experience of dealing with different architect when I opened my first center in Hicksville, Long Island. My experience the second time around has certainly been more rewarding.I find Marcelo more dedicated as a professional architect than any of the others I have dealt with. He knows all the rules and regulations so you can avoid the pit falls that can arise when you are seeking DOB approval. With his vast experience, and his attention to detail I was really glad I had Marcelo on my side.I highly reccomend him as an architect for any job you may have. This is coming from someone who knows many architects in the commmunity.

Jagdeep Vyas MD New York Urgent Care | Bellerose, N.Y.

I have personally worked with Marcelo for over two years now on both residential projects and commercial and I can tell you I have not met a more dedicated and professional architect in my many years as an inspector and an energy contractor. If you need to build an extension on your home or have to remove violations from the building department Marcelo can turn your dreams into reality. I've also seen his work on commercial buildings it is truly breathtaking. If you're looking for an architect to help you on a project of any size Marcelo is the person you need to call.

Marcelo Kohan is a true gentleman and exceptionally excellent professional! He is very talented, novel in his designs, technically innovative in his understanding and use of materials, and consideration of alternatives. Mr. Kohan’s ethical standards are known to be very high, he is a very collaborative/accessible person, quite dedicated to his profession.

Mark T. Merrick, N.Y.

Marcelo has great experience and is always very professional. We have hired his office numerous times to develop several apartment buildings throughout Queens. He's one of the few architects I've worked with who keeps customer costs in mind. Most importantly he is always reachable, fair in price and diligent in getting things done. I recommend him often!

Greg Raposo Raposo Homes | Queens, N.Y.

We were fortunate to hire Delargent Design Architecture to design, obtain permits and coordinate the building of a new addition to our home and new deck. Marcelo Kohan was exceedingly accommodating, patient, creative and professional. In short, he made it easy. We get many compliments on the work done and couldn’t be happier.”

Steven and Michele M. Bellmore, N.Y.

Marcelo is a wonderful, understanding person with a creative eye that will make your dreams a reality. Been acknowledged by his peers and others for his understanding and ability to deliver to the expectations you seek every time. He can help you!

Bob R. Hicksville, N.Y.

We used Delargent Design as our architects for our home renovation. From the initial phone call to the office and the first meeting at our home, to the home surveying, the preliminary drawings and advice along the way, they always took our calls, and got back to us promptly. Our experience with Marcelo and his team have been top notch. I highly recommend them to anyone in need of a great architectural firm.
