calderón architecture & design studio believes that architecture should respond to its environment in an organic, complementary manner. 

We create unique spaces that serve the interests of our clients, adding grace and value to buildings and their surroundings.

At calderón architecture & design studio, we believe that the design process is a collaboration between client and architect. Whether you’re undertaking a historic home renovation or new construction, we listen carefully to your vision and translate it into reality. Our depth of practical experience allows us to take on difficult problems, spot hidden potential, and bring ideas to life. 

Our clients often refer us to friends and associates after experiencing the value we place on partnership. 



Located in New York’s historic Hudson River Valley, calderón architecture & design studio specializes in commercial and residential projects. Our design-oriented architects are licensed in New York and New Jersey, and we are a certified MBE & DBE firm.


Our founder, J.C. Calderón, is the 2021 president-elect of the AIA Westchester + Hudson Valley chapter and a LEED Accredited Professional. A graduate of Williams College and the Yale School of Architecture, he has worked with firms such as Kohn Pedersen Fox, Tesoro Architects, Calvin Klein, and Simmons Architects. He regularly appears in media and on public panels to speak about design, urban culture, and green building practices.


Expanding a space 

J.C. Calderón did phenomenal work. He turned a large pre-war two-bedroom coop apartment on the Upper West Side into a three-bedroom family apartment with an intelligent design that worked for my family. J.C. spent time talking with me, my wife, and even my kids. 

By reconfiguring the floor plan to our needs, he also creatively brought natural light into the entire apartment. During construction, the seller’s real estate broker came by and could not believe the transformation. She said the apartment was worth over $300,000 more than I paid (about 25%) based on J.C.’s new layout alone, and she had not even seen the finishes.

J.C. also handled all dealings with our coop board’s approval process and worked seamlessly with our general contractor throughout the project. He ensured that all design plans were properly filed with the NYC Department of Buildings and Landmarks so that I will have no problem when I decide to sell. He navigated this project to conclusion on time with very few bumps. He was proactive and his total price was less than the other architects I interviewed, and his price never changed once we reached our agreement. I highly recommend J.C. and his team.

Catching sunlight

J.C. Calderón did a marvelous redesign and renovation of our 25-year-old Upper East Side apartment. He went to great pains to understand and fulfill our design preferences. His understanding of light, space, and color opened up the apartment both physically and visually, and the ingenious hallway cutout allowed sunlight from the corner of the bedroom to reach all the way into the kitchen.

Developing a vision

Working with J.C. enabled us to develop a clearer picture of exactly what it was that we wanted. He kept honing that picture and gave us a result that still gives us satisfaction and utility.

Increasing re-sale value

J.C. Calderón did a fantastic job with our extension. His attention to detail was amazing. The end result was spectacular. We definitely are going to see a substantial increase in our resale value.
