Home additions in Buffalo Grove, IL
Expanding a home in Buffalo Grove often means thoughtfully extending the existing footprint of a mid-century ranch or split-level, addressing the original, often compartmentalized floor plans. Many homes built in the 1960s and 70s, while well-maintained, feature smaller living areas or a lack of dedicated primary suites that no longer align with modern family needs. A home addition here typically transforms these layouts by integrating new spaces seamlessly, whether it's a rear extension for an enlarged kitchen and family room or a second-story addition to create new bedrooms. The goal is to enhance functionality and flow while maintaining the architectural character prevalent in subdivisions like Strathmore, where additions are designed to blend with existing brickwork and rooflines. These projects often involve expanding outward to create open-concept living or building upward to add vital bedroom and bathroom space, directly addressing the common desire for more expansive and versatile interiors.
What Buffalo Grove homeowners ask for
Buffalo Grove homeowners frequently request first-floor rear additions to expand kitchens and add integrated family rooms, creating the open-concept living spaces missing from their original designs. Second-story additions are also common, providing space for new primary suites with walk-in closets and spa-like bathrooms, or additional bedrooms for growing families. Another popular request involves adding a dedicated home office or sunroom, extending the living space without significantly altering the main living areas.
About Buffalo Grove
Buffalo Grove's housing stock, much of it roughly a half-century old, ranges from mid-century ranches and split-levels to slightly larger, more contemporary homes from later development phases. This variety means original kitchens, bathrooms, and unfinished basements are often due for a full rework, offering diverse opportunities for modern transformations.
Buffalo Grove grew up fast after its 1958 incorporation. Throughout the 1960s and '70s, subdivisions like the Levitt-built Strathmore filled in with ranches, split-levels, and two-story family homes, contributing to the village's population jumping 80 percent in the 1970s alone. The varied housing stock across Buffalo Grove means GS Construction approaches each project with an understanding of the specific architectural nuances and homeowner needs, from the more traditional layouts near the Raupp Museum to the slightly newer constructions further north. Homes on the Lake County side, particularly those closer to Stevenson, sometimes feature slightly larger footprints or more contemporary designs from later development phases. Areas near Mike Rylko Community Park and along Lake Cook Road have seen continuous investment and development, reflecting a community that values both its established neighborhoods and modern amenities. With two North Central Service Metra stations — Buffalo Grove and Prairie View — and the Town Center reborn as The Clove, this is a town reinvesting in itself — homes included. The transformation of The Clove, for example, mirrors the desire of many residents to update their own living spaces to better suit contemporary lifestyles while remaining rooted in the community.
What that means for home additions in Buffalo Grove: The rapid growth of subdivisions like Strathmore in the 1960s and '70s often means existing ranches, split-levels, and two-story homes were built on lots with specific setbacks that must be respected when planning additions. Homes on the Lake County side, especially those closer to Stevenson, sometimes offer slightly larger footprints or more contemporary designs from later development phases, potentially allowing for more expansive additions. Tying into the original rooflines and foundations of these roughly half-century-old homes is crucial for seamless integration, particularly in areas near Mike Rylko Community Park and along Lake Cook Road where continuous investment is evident. While Buffalo Grove lacks a historic district, the village's established permitting processes and building codes require careful plan review of exterior changes to maintain residential character, ensuring additions enhance existing homes within established parameters. The village's commitment to maintaining its residential character means that while teardowns and infill development occur, they are typically within established parameters, allowing for significant remodeling and additions that enhance existing homes rather than replace them entirely.
Home additions in Buffalo Grove require comprehensive plan review by the Community Development Department for structural integrity, foundation work, new roof tie-ins, and all new electrical, plumbing, and HVAC systems. GS Construction & Remodeling manages the complete application submission, including detailed drawings, and coordinates all necessary inspections throughout the construction process.

Your Neighbours in Buffalo Grove Love Us
Real reviews from homeowners. Ask us for live phone references.
They did an outstanding job on our complete bathroom renovation! Our bathroom was an icebox due to poor insulation from the original build. They made excellent design recommendations to resolve the poor insulation and also installed heated floors. They converted an outdated tub/ shower combo into a beautiful walk-in shower and we are thrilled with the results . Their team was prompt, courteous and clean, taking off shoes and wiping down the area which with a toddler in the home was extra appreciated. They even helped us install a shower rod in another bathroom that was not part of the project. We are so happy they were recommended to us and we would definitely recommend them for your project.
