Jim Spontarelli brings experience from modular manufacturing and on-site homebuilding. He helps coordinate the design, manufacturer, lender, and local trades around your agreed scope.
A modular home can begin with a Signature Building Systems ranch, cape, chalet, or two-story plan. Bring your ideas for room sizes, an open kitchen, a first-floor bedroom, or a custom layout. Jim can help you understand the options before final plans are prepared.

The total budget
Consider the modules alongside excavation, foundation, permits, delivery, set, utilities, and on-site completion. The project proposal should explain what is included and which work is handled by others.
The next milestones
Coordinate financing, local approvals, manufacturer plans, production, and site preparation. The timeline depends on your design, location, approvals, and the work needed on your lot.
