Common Remodeling Challenges for Homes in Highland Park, Illinois Include:
Adding on in Highland Park often means working with ravine lots, mature trees, and the architecture of a Prairie-style or mid-century home. The challenge is expanding the house — a primary suite, family room, or second story — without disrupting the setting or the original design.
We design and build additions throughout Highland Park and handle the City of Highland Park permits and setbacks, including ravine and tree considerations. We match the new space to the home’s proportions and materials.
Family Expansion
Additions in Highland Park clear City of Highland Park zoning, setbacks, and permits — with extra care on ravine and bluff lots. We manage the approvals and inspections so the project moves without surprises.
Large Lot Design
Adding to a Prairie-style, mid-century, or historic Highland Park home means matching its proportions, rooflines, and materials. We design additions that read as original to the house, not bolted on.
Historic Preservation
Highland Park families add on for primary suites, family rooms, and space that opens to wooded ravine lots. We plan additions around how your household lives while protecting the home's character.
The Right Approach For Your Highland Park Home Addition
Whether you need to add extra room for a growing family or a second level to your home, our team will help you find the best way to expand your space.
Single Level Additions
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.
Second Story Additions
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.
Basement Additions
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.

Frequently Asked Questions
Can my Highland Park home support a second-story addition?
Many North Shore colonials, Tudors, and traditional homes in Highland Park are built on foundations capable of supporting an upper level, but it requires a structural assessment. Pegasus works with licensed engineers to evaluate your existing framing, foundation, and load paths before committing to a design. We will not promise a second story until we know the structure can handle it.
Is a dormer or attic conversion more cost-effective than a full addition in Highland Park?
Often yes. Converting an existing attic with dormers can add significant livable square footage at 30 to 40 percent lower cost than a ground-up addition because the foundation and exterior walls already exist. Pegasus will price both options so you can compare real numbers before deciding.
How much does a home addition cost in Highland Park?
In Highland Park, home additions typically run $150 to $250 per square foot for a fully finished, permitted addition including framing, mechanical, electrical, plumbing, and finishes. Complexity and site access affect where you land in that range. You receive a detailed estimate before any contract is signed.
How long does the Highland Park Building Department take to approve an addition permit in Highland Park?
Permit approval through the Highland Park Building Department in Highland Park typically takes four to eight weeks depending on project complexity and current review volume. Pegasus submits complete, code-compliant drawings the first time to avoid back-and-forth that delays the clock. Permit timelines are built into the project schedule from day one.
How do you match a new addition to my existing Highland Park home’s architecture?
Matching North Shore colonials, Tudors, and traditional homes requires attention to roof pitch, exterior materials, window proportions, and trim profiles. Pegasus sources the same siding species, brick veneer, and roofing materials as your existing home wherever possible so the addition looks like it was always there.
What zoning and setback rules apply to home additions in Highland Park?
The Highland Park Building Department in Highland Park enforces setback requirements limiting how close structures can be to property lines, and zoning codes cap total lot coverage. Pegasus researches your specific parcel restrictions before design begins so there are no scope surprises after plans are drawn.
