We're All About the Details

Your Long Island Custom Home Builder

The Calvosa Organization has been building custom and semi-custom homes in Long Island for almost 30 years. The quality of The Calvosa Organization team is built upon years of relationships. We continually bring together a team of master craftsmen for the benefit of our clients. The result is always a job done correctly the first time. On a Calvosa Organization job site, it is not unusual to see Master Craftsmen with 30 years or more of experience, and tradesmen with extraordinary skills, working together with insight, harmony and passion. We are strongly committed to superior craftsmanship and a “customer first” mission.

We pride ourselves in providing a product of value, through innovative design and superior construction.

What Makes us Different

Each and every home that we build in Long Island is meticulously overseen by our owner, who is a Master Carpenter. He has worked on every job that can be done in conjunction with home building and has studied all the trades. He inspects every job personally to ensure that The Calvosa standards are being met every time. This attention to detail means that your new home will be built with care and will be something we can proudly put our name on.
