Northfield homeowners add on to stay on the North Shore and in the schools — primary-suite wings, family-room expansions, and second stories. The generous lots usually leave room, and the Village of Northfield sets the zoning and setbacks. We design Northfield additions that match the home’s character and clear the village review.
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.”
Often yes, but mid-century ranches must be verified. We evaluate the foundation and framing and involve a structural engineer before designing up.
Sometimes, though many Northfield lots have room to expand outward. We compare both against your goals and budget.
In Northfield, additions typically run $250 to $400 per square foot, with custom-match work and high-end finishes on the upper end. We provide a fixed budget after design.
Permitting through the Village of Northfield generally takes several weeks to a couple of months depending on scope and variances. We handle the submittal and review.
We document the existing rooflines, masonry, and trim and specify matching materials so the addition looks original and protects resale value.
The Village of Northfield enforces setbacks, lot-coverage, and height limits that vary by district. We confirm all of it before finalizing the design.
