This marks the kickoff of our new website. It’s an exciting time at JCA! J. Costantin Architecture was started just about 5 years ago with a core value that the clients’ best and highest interests are served first. Our growth is testimony to the fact that they appreciate that focus. Please peruse our site. We will be adding more and more exciting projects monthly. Look through our design plan and elevation sketches. See our fantastic AutoCAD/Revit model that we create for every project. You’ll see how much more clear your project will be before construction starts!

J. Costantin Architecture

Our body of work varies from 300 sq. ft. additions in Watchung to a 30,000 sq. ft. Country French estate in Colts Neck. Our design work spreads as far south as Costa Rica, north as Upper Saddle River, NJ, East as Sagaponack NY, and west as Sun Valley, Idaho.

Our “architectural style” is as varied as the clients who inspire us. With building technology continually advancing and the incredible efficiency of “Smart House” technology tied to the mechanical systems, even large houses become more manageable to condition. Indoor pools, flat roof terraces, indoor sports courts, waterfalls, indoor gardens are all done and controlled for a non-worried peace of mind.

Someone in our firm will periodically check in with communication about design and technology things we’ve learned along the way. I welcome your feedback!
