Home additions in Des Plaines, IL

Expanding your home in Des Plaines often means building upon the strong foundations of its mid-century housing stock. Many ranches and Cape Cods in neighborhoods like Lake Park or Devonshire, originally built with smaller footprints, are ideal candidates for additions that respect their architectural heritage while dramatically increasing living space. We frequently see projects transforming compact layouts by adding second stories or expanding rearward, extending kitchens, family rooms, or creating dedicated primary suites. These additions are designed to seamlessly integrate with the existing structure, both aesthetically and functionally, addressing the common desire for more open, versatile areas in homes from the 1950s and 60s.

What Des Plaines homeowners ask for

Des Plaines homeowners frequently request additions that create spacious primary suites, often integrating a walk-in closet and larger bathroom. Another common desire is for expanded family rooms or sunrooms, particularly at the rear of the home, to gain more light and direct access to outdoor living. Second-story additions are also popular for adding bedrooms or office space, allowing families to grow without moving.

About Des Plaines

Des Plaines is a postwar boom town, with ranches, Cape Cods, split-levels, and bi-levels filling in around a historic downtown. Remodeling here usually means opening up compartmentalized floor plans, rebuilding original bathrooms, or adding space.

How your Des Plaines project runs

Process

The same six stages on every job — free in-home estimate through warranty.

1

Free in-home estimate

Greg or Patryk — the owners, not a salesperson — walk your space, take real measurements, and give you honest feedback on what your budget buys.

2

Itemized scope & contract

Labor, materials, demolition and disposal priced line by line, not one mystery number. Payment terms and warranty are in the written contract.

3

Design & selections

Bring your own designer, use our architects and designers, or choose everything yourself. Selections are scheduled ahead so lead times never stall the site.

4

Permits & scheduling

We pull and manage building, plumbing and electrical permits with your village — typically 1–2 weeks — and hand you a written schedule before demo day.

5

The build, owner-supervised

Long-standing trade partners working in sequence under daily owner supervision. Your client portal shows the schedule, change orders and current balance.

6

Walkthrough & warranty

We walk the finished job together, close out every punch-list item, hand over manufacturer paperwork, and your written workmanship warranty starts. Our commitment never expires.

Real reviews from homeowners. Ask us for live phone references.

Greg and Patryk do amazing work and are incredible to work with! GS Construction completed two extensive bathroom renovations for us, including completely reconfiguring layouts and expanding one. Both bathrooms are absolutely beautiful, and they have significantly improved our family's quality of life in our home. Patryk and Greg are great communicators, take pride in their work, and have good attention to detail. Throughout the project, they really listened to us, took the time to understand what we wanted, kept progress going in a timely manner, and provided expert advice/suggestions and help on specific questions along the way. Every one of their team members did high-quality work. We couldn't be happier with the end result, and definitely will hire them for future renovations!
