A successful home remodel starts with a clear plan. With hundreds of satisfied Evanston customers, our proven 6-Step Design-Build Process ensures a smooth and stress-free remodeling experience.
1 in 3 remodels exceed their budget—but yours doesn’t have to. At Pegasus Construction, we’ve created a budgeting system to eliminate surprise costs, with our projects averaging just a 5% variance from the initial budget to the final price.
Feel confident knowing your home remodel is managed by experts. Each project is assigned a dedicated team, led by an experienced master carpenter, ensuring timely completion. While other companies face delays of weeks or months, our projects average less than a 2-day difference from the original schedule.
Whether you’re adding to a Victorian on the Ridge, expanding a Craftsman bungalow, or building a rear addition on a Tudor Revival in the Oakton district, we’ll help you find the right approach for your Evanston home.
Home additions in Evanston require permits through the City permit desk at 909 Davis Street and zoning review for setbacks and lot coverage. Properties in the Ridge, Lakeshore, or Oakton historic districts also require Preservation Commission approval for exterior modifications before permits can be issued. We handle both processes before any construction begins.
Evanston's Victorians, Craftsmans, and Tudor Revivals have specific architectural vocabularies — rooflines, trim details, material palettes — that a poorly designed addition will undermine immediately. We design additions that speak the same architectural language as the existing home so the addition looks like it was always part of the plan.
Evanston sits at the convergence of the North Shore, Lake Michigan, and the Purple Line to Chicago — a location homeowners rarely give up voluntarily. A well-planned addition is how residents of the city's Victorian and Craftsman homes get the space their families need without giving up an address that would cost significantly more to replicate.
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.
