DePaul’s housing is mostly 1890s–1920s greystones, Victorian frame houses, and Lincoln Park two-flats on narrow city lots. Adding on here means working within tight setbacks, historic blocks, and century-old structures.
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.

Common DePaul additions are dormer and second-story additions on greystones and frame houses, rear additions, and finished lower levels. On these narrow Lincoln Park lots, gaining space usually means building up or back rather than out.
Yes, and additions get more review than interior work. They need a permit from the Chicago Department of Buildings at 121 N. LaSalle Street, plus zoning review and sometimes landmark review. We handle the drawings, submission, and inspections.
DePaul’s standard city lots are tight, and Chicago zoning controls setbacks, height, and lot coverage. We pull your lot’s zoning before we design so the addition is something the City will actually approve.
Often yes — it’s a common way to add bedrooms on a narrow lot. The key is whether the existing masonry and foundation can carry the load, so we evaluate the structure before promising a second story and reinforce it where needed.
They can. Blocks in Sheffield and the Mid-North District near DePaul are Chicago landmark areas, so exterior additions there go through the Commission on Chicago Landmarks. We manage that review and design the addition to meet it.
DePaul additions vary widely — a dormer or rear addition might start around $100,000, while a full second-story addition can run $300,000 or more. We give you a fixed, itemized number once the design is set.
Plan on roughly 5 to 9 months from design to finish, including Chicago permitting and any landmark review, which runs longer than the suburbs. We give you a real schedule up front.
That’s the goal. DePaul is full of greystones and Victorians with strong character, and a good addition should read like original construction — matching limestone, brick, rooflines, and window proportions so it looks like it was always there.
