Home additions in Lake Zurich, IL

Expanding your footprint in Lake Zurich often involves thoughtful additions to homes from various eras. For the charming, older cottages near the lake, an addition might mean a seamless extension that respects their historic character, perhaps adding a dedicated master suite or a sunroom while carefully matching existing rooflines and siding. In the prevalent split-levels, tri-levels, and ranches of Old Mill Grove and Quail Run, additions frequently target the lack of a spacious primary suite, a dedicated home office, or a larger, open-concept kitchen that flows into an expanded dining area. These projects often involve building out or up to create the modern living spaces these well-built homes now lack, transforming their original, more compartmentalized layouts into open, airy environments perfect for contemporary family life.

What Lake Zurich homeowners ask for

Lake Zurich homeowners frequently seek two-story additions to create luxurious primary suites, often above an existing garage or extending from the rear of the home. Expanding kitchens into larger, open-concept spaces with an adjacent family room addition is also a common request, especially in the mid-century homes. Another popular choice involves adding dedicated home offices or mudrooms, particularly in homes where the original footprint didn't account for these modern necessities. We also see requests for second-story additions on single-story ranches, effectively doubling the living space and providing multiple new bedrooms and bathrooms.

About Lake Zurich

Lake Zurich homes range from expanded early cottages near the lake to distinct subdivision waves from the 1950s onward, presenting unique opportunities and challenges for modern renovation. This diverse housing stock calls for thoughtful updates and comprehensive remodels to suit contemporary family life.

How your Lake Zurich 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.

Our project turned out better than we expected and as things were going along, we added more projects. Patryk, Greg and their team did a fantastic job. They were always so nice to work with, even suggesting things which was helpful. They never left a project until they thought it was perfect. We did a full kitchen remodel, even closing off a window to move a fridge and pantry to the other side to allow more cabinets and much needed counter space. They widen the entrance and the kitchen seems so much bigger. We think it’s Beautiful! They did laminated floors throughout the first floor, painted all walls and new baseboards. They created a wine bar which was just a cubby hole. They put in a pantry like cubby hole in our laundry room and added cabinets and above wall unit. One of the projects we had them add is new wooden stairs to the 2nd floor, white spindles and railing that curves instead of a wall and laminate floors on the 2nd floor. Other odd and ends that they never hesitated to do. We appreciate all they have done in our home, To us, it’s amazing how nice it is and how it should have been all the years we have lived here. Its exciting to show it off, it feels like a new house. These guys are amazing and would definately recommend them to anyone. Very reliable and easy to get in contact with when needed.
