North Shore builders since 1996.

J.P. Construction was founded by Janusz Perkowski with a straightforward promise: deliver honest craftsmanship and stand behind every detail. Nearly three decades later, that owner-led approach continues to shape high-end renovations, additions, and custom homes across Deerfield, Bannockburn, Evanston, and neighboring communities.

We have completed projects throughout the North Shore, collaborating with architects and designers to balance heritage aesthetics with modern livability. From Riverwoods retreats to Buffalo Grove additions, our work is tailored to the families who call them home.
