Giuseppe-Abbrancati
- OUR FOUNDER

Giuseppe Abbrancati —
Built by Hand, Since Age 7

Giuseppe Abbrancati began working in construction alongside his father and grandfather in Italy in 1974, at just seven years old. At 16, he moved to Milan to work with a full-service construction company. At 20, he immigrated to Long Island, and by age 21, he had founded Gappsi in Smithtown, NY.

For over 38 years, Giuseppe and the Gappsi team have grown the company into a full-service construction firm with 10 divisions, a dedicated showroom, and a reputation for award-winning design throughout Nassau and Suffolk County.

CONSULTATION

Meet with Giuseppe or a Gappsi designer at our Smithtown showroom or on your property. We evaluate your space, and discuss goals. No pressure, just expert guidance.

02

3D DESIGN

We produce a complete 3D design rendering of your project before any construction begins, so you can visualize the finished result, explore material options, and make changes at zero cost.

03

PERMITTING

Gappsi handles all permits, architectural drawings, and engineering stamps across Nassau County, Suffolk County, Southampton, and New York.City.

04

CONSTRUCTION
