Evanston’s housing ranges from Victorians and four-squares to brick Georgians, frame homes, and two-flats, many on historic blocks near the lake. Adding on means working within City setbacks, historic-district review, and the existing structure.
If you find yourself needing more living space and want to expand your home rather than upsize, a single-level addition is the place to start.
The most cost-effective way to add living space, a single-level addition attaches to the side of the home. They typically require expanding the home’s foundation, and are most often used for expanding kitchens, living rooms, or home offices.
Single-level additions are typically limited by lot size and setback laws. For this reason, these additions are better fit for homes on larger lots.


Want to expand your home without expanding its footprint? Many homeowners don’t realize it’s possible to expand their living space by adding a second story.
Although often more expensive than single-level additions, second-story additions can be a great solution for homeowners who need additional living space but don’t have enough yard space to build out.
Second-story additions tend to be more technically challenging, as they require extensive engineering and planning to ensure that they don’t disrupt the design or aesthetic of the existing structure.
For some homeowners, a basement addition is the best way to expand their living space. This often involves either raising the home or digging out the crawl space.
Homeowners who go this route often use their basement for additional bedrooms, a recreational space, or an Accessory Dwelling Unit (ADU).
Basement additions are among the most expensive methods of adding onto a home. Extensive manual labor, planning, and permitting all contribute to the high cost of basement additions.

At Pegasus Construction our mission is to change the lives of homeowners by helping them expand their homes with custom home additions built just for them. However, we also recognize that not every home addition project is the right fit for our team. Here is how to tell if Pegasus Construction is or isn’t a good fit for your home addition project.

“…I felt truly heard and valued during our conversation. I came to your company with questions about our projects, and Greg provided thoughtful, flexible scenarios and options to help us achieve our goals. He genuinely seemed to care about me and my family as real people.”
Common Evanston additions are primary-suite and family-room additions, dormer and second-story additions on Victorians and four-squares, and rear kitchen expansions. The right approach depends on the home, the lot, and any historic-district rules.
Yes, and additions get more review than interior work. Any addition needs a permit and zoning review from the City of Evanston at the Civic Center, 2100 Ridge Avenue, plus preservation review if your home is in a historic district. We handle the drawings, submission, and inspections.
Yes, for exterior work. Evanston has several historic districts and many landmark homes, so additions visible from the street go through preservation review. We manage that review and design the addition to meet it.
Evanston has side-, front-, and rear-yard setbacks plus lot-coverage limits, on top of any historic rules. Before we design anything we pull your lot’s zoning so the addition is something the City will actually approve.
Often yes, though older homes and historic districts add considerations. The key is whether the existing framing and foundation can carry the load, so we evaluate the structure before promising a second story and reinforce where needed.
Evanston additions vary widely — a rear or room addition might start around $100,000, while a large primary-suite or second-story addition can run $300,000 or more, especially with historic requirements. We give you a fixed, itemized number once the design is set.
Plan on roughly 5 to 10 months from design to finish, including Evanston permitting and any preservation review, which adds time up front. We give you a real schedule, not an optimistic guess.
That’s the goal, and in a historic district it’s required. Evanston is full of Victorians, four-squares, and Georgians, and a good addition should match the materials, rooflines, and proportions so it reads like original construction.
