Home Additions & Whole Home Remodeling

Room additions, second stories, and whole-home renovations — one design-build team from first sketch to final walkthrough.

Expert Home Additions & Whole Home Remodeling

When your home no longer fits your life, you have two choices: buy a new one in an expensive market, or make the home you love work harder. Our home additions and whole-home remodeling service is built around the second option. Using a true design-build approach — one team from design through construction — we handle room additions, sunrooms, second-story additions, open-concept conversions, in-law suites, and full-home renovations. Permits and zoning, fixed-price proposals, a dedicated project manager, and a post-project warranty walkthrough are all part of how we work, so a project this big never feels chaotic.

How We Get the Job Done

Our process is designed for safety, efficiency, and quality at every step. We don't cut corners — we follow a proven system that delivers consistent, exceptional results.

Consultation & Feasibility

We sit down to understand how you want the home to live, then assess feasibility — structure, lot, zoning setbacks, and budget. You leave the first meeting with an honest read on what's possible and what it takes.

Design & Fixed-Price Proposal

Because we're design-build, our team develops the plans, selections, and scope together — no handoff between a separate architect and builder. You approve a fixed-price proposal with clear line items before construction begins.

Permits & Zoning

We handle permit applications, zoning review, and any variance work with your village, and we coordinate inspections throughout. You don't chase paperwork — that's our job.

Site Prep & Foundation/Structure

We protect the existing home, then build the foundation, framing, and structural work for the addition or reconfiguration — tied cleanly into the existing structure so the new space feels original, not bolted on.

Systems & Weather-Tight Shell

Licensed trades run HVAC, plumbing, and electrical; we install roofing, windows, siding, and insulation to get the addition weather-tight and matched to the existing exterior.

Interior Finishes

Drywall, trim, flooring, cabinetry, tile, and paint are completed to the same detail-first standard we built painting North Shore homes — so the finish quality inside matches the ambition of the project.

Walkthrough & Warranty Follow-Ups

We complete a final walkthrough and punch list with you, then return for scheduled warranty walkthroughs at 45 days and 11 months to catch settling items and confirm everything is performing as it should.

Materials We Use

We only use professional-grade products from trusted brands. The quality of materials is just as important as the quality of application — and we never compromise on either.

Engineered Lumber & Structural Steel

Engineered beams, LVLs, and steel where spans and open-concept layouts demand it — sized by structural design for safe, code-compliant load paths.

Andersen & Marvin Windows

Quality windows matched to your home's existing style and rated for Chicago's climate — energy-efficient, durable, and warranty-backed.

Matched Siding & Roofing

Siding, trim, and roofing sourced and blended to match your existing exterior so an addition reads as part of the original home.

Closed-Cell Spray Foam & Batt Insulation

High-performance insulation packages for additions and renovations that keep new space comfortable and energy-efficient year-round.

James Hardie Fiber Cement

A durable, low-maintenance siding option for additions and whole-home exteriors — resists moisture, rot, and Chicago's freeze-thaw cycles.

Premium Interior Finishes

Cabinetry, tile, flooring, millwork, and Sherwin-Williams and Benjamin Moore paints — the same finish materials and standard we bring to every project.
