Home additions in Evanston, IL

Home additions in Evanston frequently involve expanding the footprint of classic foursquares and Victorians, often to create more expansive kitchen and family room areas on the ground floor. For brick bungalows and two-flats west of Ridge Avenue, additions typically focus on rear bump-outs to alleviate compact layouts or add a much-needed mudroom and larger primary suite. Many projects involve tying into existing structures built a century or more ago, requiring careful planning to blend new and old seamlessly, both structurally and aesthetically. Expanding upward with a second-story addition is also common, particularly on smaller lots, to accommodate growing families without sacrificing yard space. We often address the challenge of matching exterior materials, from period-appropriate brick and limestone to cedar shakes and clapboard, ensuring the addition looks original to the home. These projects fundamentally transform the home's functionality and flow, adapting historic residences for contemporary living.

What Evanston homeowners ask for

Evanston homeowners frequently request two-story rear additions to create larger, open-concept kitchen and family rooms on the first floor, with additional bedrooms or a primary suite above. Another common request is for side additions that expand existing living areas or add a dedicated home office, blending with the existing architectural style. Sunrooms and screened porches are also popular, particularly for homes with ample backyard space, extending living areas into the outdoor environment.

About Evanston

Evanston remodels differently than the villages to its north: it is a full-sized city with a rich tapestry of architectural styles reflecting its growth from the mid-19th century onward. These homes often present unique remodeling challenges and opportunities.

How your Evanston 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.
