Home additions in Harwood Heights, IL

Expanding a home in Harwood Heights frequently involves working with the sturdy brick ranches and bungalows built from the late 1940s through the 1970s. These homes, while well-constructed, often feature compact original footprints that leave little room for growing families or evolving lifestyle needs. A typical home addition here transforms these layouts by extending living areas, adding new bedrooms, or creating dedicated workspaces. The goal is often to maximize usable square footage without sacrificing the character of the original mid-century architecture, thoughtfully integrating new construction with existing structures. This often means carefully considering how new spaces flow from older ones, especially in homes with distinct living and dining areas.

What Harwood Heights homeowners ask for

Harwood Heights homeowners frequently request family room additions to create more spacious gathering areas, often extending off the back of existing living rooms or kitchens. Second-story additions are also common, particularly on single-story ranches, to efficiently add multiple bedrooms and bathrooms without consuming valuable yard space. We also see demand for mudroom and laundry room additions, as many older homes lack these dedicated functional spaces.

About Harwood Heights

Harwood Heights squeezes a lot of postwar suburbia into 0.83 square miles. Remodeling here works within tight footprints, so finished basements, reworked kitchens, and well-planned additions often beat moving.

How your Harwood Heights 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.

My designer and I chose GS Construction for the rehab of my kitchen and other small projects in my newly purchased condo. They were recomended by a client of the designer, Mark Zancanaro Design, who raved about their professionalism and communication, as well as their skill. It was the best decision I made. Greg and Patryk were prompt, courteous and extremely knowledgeable. They listened to what I wanted and their attention to detail was greatly appreciated. They were not satisfied until everything was absoutley perfect. I would highly recommend them to anyone looking for a reliable and skilled construction company to complete any size project in their home or office. They will definitley be called for any future projects in my new home.
