Jon Bijari began his career in 2001, learning the craft of homebuilding from the ground up on job sites in Brooklyn. He progressed to larger residences across Queens before growing demand for his work drew him into Long Island’s high-end luxury market in 2008. Today, with projects spanning Manhattan to the Hamptons, Jon has established a reputation as one of Long Island’s premier luxury home builders.
His approach combines extensive knowledge of construction science, a command of the latest building products and technologies, and a keen understanding of architecture and interior design. More than a builder, Jon serves as a trusted guide throughout the entire process—from securing the right property and collaborating with architects and designers to overseeing construction, coordinating furnishings, and delivering a fully finished home. His hands-on involvement brings clarity, continuity, and personal attention to every stage.

Building independently
Independent residential work across New York's boroughs expanded the scale and design ambition of each project—and developed the habit of resolving details directly with the people building them.
Entering the Long Island luxury market
Jon opened Rockwell Developers and spent more than a decade building for exacting clients on Long Island. The experience strengthened his approach to complex estates, highly coordinated interiors, and close collaboration with leading design teams.
Jon Bijari Custom Homes
The current practice brings those lessons into a focused, hands-on relationship: luxury custom home building as the primary service, with owner's representation available for homeowners who have selected another project team but want Jon's experience on their side.

What Experience Changes
Seeing the issue before it becomes expensive
Luxury residential construction demands more than knowing how to assemble a building. It requires an understanding of how design decisions affect structure, systems, procurement, sequencing, finish quality, maintenance, budget, and the homeowner's daily life.
Years in the field make small warning signs easier to recognize. A missing dimension, an uncoordinated transition, a late selection, an unrealistic allowance, or an unanswered responsibility can grow into a major delay or visible compromise. Jon's role is to bring those questions forward early.
One standard from planning through completion
The same priorities should survive every phase: the architecture, the homeowner's intent, the level of workmanship, and the agreed financial and schedule controls. Whether Jon is the builder or acting as the homeowner's representative, the work is organized around clear decisions, direct communication, and accountable follow-through.
