J.P. Construction team reviewing architectural plans
Our Story

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.

As a fully licensed general contractor, we manage the entire build under one roof — demolition, structural framing, plumbing, electrical, tile, custom cabinetry, and finish carpentry — so you have a single point of accountability from the first walkthrough to the final walkthrough. That control over every trade is what keeps timelines realistic, job sites clean, and the finished details consistent.

What we build

Remodeling and custom building across the North Shore.

J.P. Construction specializes in high-end bathroom and kitchen remodeling, but our work spans far beyond a single room. We design and build home additions, finish basements, reconfigure floor plans, and carry out whole-home renovations for clients in Highland Park, Deerfield, Buffalo Grove, Lincolnshire, and the surrounding communities.

Every project starts with an honest conversation about scope, budget, and timeline. We walk the space, talk through what you actually want to change, and provide a clear written estimate — no vague ballparks and no pressure. Older North Shore homes often need their plumbing and electrical brought up to code along the way, and because we handle those trades ourselves, surprises get caught early instead of mid-project.

Janusz Perkowski

Owner & Principal Builder

Established J.P. Construction in 1996 and still leads every project review and on-site coordination meeting. Many North Shore families have worked with Janusz across multiple homes and decades, and his hands-on involvement is why so much of the firm’s work comes from referrals and repeat clients.
