Home additions in Highland Park, IL

Expanding a home in Highland Park often means blending new construction seamlessly with established architectural styles, whether it's a 1920s Tudor or a mid-century ranch. Many homeowners are looking to create more expansive living areas, adding square footage to homes originally designed with more compartmentalized layouts. This can involve extending a rear facade for a larger kitchen and family room, or building up to add a primary suite above an existing garage. The challenge and beauty lie in respecting the original footprint and aesthetic, ensuring the addition looks and feels like an organic part of the home's history. We frequently work with properties that require careful consideration of their period-specific details and materials.

What Highland Park homeowners ask for

Highland Park homeowners frequently request two-story additions to expand living space without sacrificing yard area, especially on narrower lots. Another common request is for single-story rear additions to create open-concept kitchen and family rooms, improving flow and maximizing natural light. Many also seek to add dedicated home offices or first-floor primary suites, adapting their existing homes to evolving lifestyle needs.

About Highland Park

Highland Park has been building homes since its 1869 founding, and its streets show it. The city’s rich architectural tapestry reflects a journey from early Victorian and Queen Anne styles, particularly around the original downtown core, through the Arts and Crafts movement, and into the widespread influence of Prairie School design.

How your Highland Park 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.

We have used GS for two bathroom projects-the first a small update; the second a complete remodel. We were thrilled with both. Everything was as promised; the timeline, price, and what it would look like. We were able to buy our own tile and fixtures and were not tied to any company's showroom. We got what we wanted and likely saved money doing so. GS also installed interior doors. The workmanship was great. The only downside is that now the bathrooms are the two nicest rooms in the house! I would heartily recommend GS construction!
