Adding on in Lake Forest means working with significant historic architecture, wooded ravine lots, and a city that strongly protects its character. The challenge is expanding a landmark-quality estate so it reads as part of the original.
We design and build additions throughout Lake Forest and handle the City of Lake Forest permits and historic-review considerations. We match the new space to the home’s proportions, materials, and rooflines.
Family Expansion
Additions in Lake Forest clear City of Lake Forest zoning, setbacks, ravine considerations, and historic review. We manage the approvals and inspections so the project moves without surprises.
Luxury Customization
Adding to a Lake Forest Tudor, Georgian, or Colonial estate means matching its masonry, trim, and rooflines exactly. We design additions that read as part of the original architecture, not bolted on.

The Right Approach For Your Lake Forest 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 Lake Forest home support a second-story addition?
Many North Shore colonials, Tudors, and traditional homes in Lake Forest 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 Lake Forest?
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 Lake Forest?
In Lake Forest, 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 Lake Forest Building Department take to approve an addition permit in Lake Forest?
Permit approval through the Lake Forest Building Department in Lake Forest 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 Lake Forest 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 Lake Forest?
The Lake Forest Building Department in Lake Forest 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.
