Home additions in Lake Forest, IL
Expanding a home in Lake Forest means gracefully integrating new construction with existing architecture, particularly for the stately brick Georgians and Tudors near Market Square or the expansive country estates. Many homes, while grand, feature layouts from earlier eras that homeowners now find less functional for modern living. A typical home addition project here might transform a smaller kitchen into an open-concept great room, or add a dedicated primary suite wing to a mid-century ranch. This involves careful consideration of the original footprint, ensuring new spaces flow seamlessly and maintain the property's character. Whether expanding living areas or adding new rooms, the goal is always to enhance both functionality and the home's intrinsic value.
What Lake Forest homeowners ask for
Lake Forest homeowners frequently request two-story additions to expand their living space without consuming excessive yard area, often for new primary suites or expanded family rooms. For mid-century and post-war ranches, a common ask is to add a second story to capture additional bedrooms or home office space, fundamentally transforming the home's scale. We also see requests for larger, more private home offices and dedicated entertainment areas, reflecting a desire for specialized spaces within their expansive properties.
About Lake Forest
Lake Forest remodeling means working inside some of the North Shore's most pedigreed housing: country-place-era estates off Green Bay Road, brick Georgians and Tudors near Market Square, and postwar ranches and newer construction farther west.
Lake Forest has country-place-era estates off Green Bay Road, brick Georgians and Tudors near Market Square — the 1916 Howard Van Doren Shaw development often cited as the nation's first planned shopping center — and postwar ranches and newer construction farther west. Five local historic districts, including East Lake Forest and Vine/Oakwood/Green Bay Road, put exterior changes in front of the city's Historic Preservation Commission.
The country-place-era estates and brick Georgians and Tudors near Market Square often present large lots but require careful consideration of existing roof lines and foundations for seamless additions. Postwar ranches and newer construction farther west may offer more flexible lot sizes for expansion, yet still demand thoughtful integration of new structures. Additions to homes within the five local historic districts, such as East Lake Forest and Vine/Oakwood/Green Bay Road, will undergo review by the city's Historic Preservation Commission for exterior changes. Tying into existing roof lines and foundations is crucial across all eras, particularly for two-story additions or new primary suite wings. The city's review process for exterior changes emphasizes maintaining the original character, especially for homes in and around the 1916 Howard Van Doren Shaw development. For plumbing-heavy remodels, homeowners are responsible for the service line from the city main to the house, which can impact foundation work and utility tie-ins.
Home additions in Lake Forest require specific inspections at various stages, including foundation, framing, plumbing, electrical, and mechanical, as well as final occupancy. Tying a new roof into an existing structure and matching exterior materials are key elements that trigger detailed plan review. GS Construction & Remodeling expertly navigates these specific applications and schedules all necessary inspections on your behalf.

Real reviews from homeowners. Ask us for live phone references.
GS Construction & Remodeling is the best of the best. We've hired them to work on 5 different properties (4 were extensive remodels) and continue to be thrilled with their work and have referred them to friends and family. I constantly bring to them pictures/ideas from Houzz & Pinterest and ask how we can duplicate high end looks on a budget and they pull it off - magnificently - every time. Not only do they know their craft, but they have a great design sense as well and make suggestions that always enhance the project. Their communication (providing estimates for changes as we go along, keeping in touch regarding scheduling, etc.) is excellent. They're nice people and incredibly respectful too - top notch all around.
