Home additions in Green Oaks, IL
Home additions in Green Oaks often address the unique characteristics of custom homes built during the village's initial growth wave (1960s-80s) or the later subdivisions of the 1980s and 90s. These projects frequently expand existing footprints, adding functional space to homes that, while large, may not always align with contemporary layouts or family needs. Many homes in Green Oaks, particularly those on larger, wooded lots, offer ample space for horizontal expansion, creating opportunities for significant changes to their original design. We commonly extend living areas, integrate new rooms into existing structures, or add second stories where appropriate, transforming the overall flow and utility of these established residences. The goal is typically to modernize and enlarge without sacrificing the architectural integrity of the original home, ensuring a seamless transition between old and new construction. This often involves updating the home's aesthetic while gaining valuable square footage tailored to the homeowner's lifestyle.
What Green Oaks homeowners ask for
Green Oaks homeowners frequently request primary suite additions, expanding smaller bedrooms and bathrooms into luxurious retreats, often incorporating walk-in closets. We also see strong demand for multi-generational living spaces, such as in-law suites or private guest quarters, given the generous lot sizes that allow for detached or attached structures. Expansive family room additions that open onto outdoor living areas are also highly sought after, especially in homes from the 1970s and 80s that often feature more compartmentalized layouts.
About Green Oaks
Green Oaks features custom homes on one-, two-, and five-acre wooded lots, a legacy of its incorporation in 1960 as a buffer against dense development. This means generous footprints for remodeling projects, from basement finishing to whole-home updates.
Green Oaks incorporated in 1960 — renamed from the old Village of Oak Grove — as a deliberate buffer against dense development, zoned from the start for single-family homes on one-, two-, and five-acre wooded lots. The housing follows that story: custom homes on acreage from the village's 1960s–80s growth wave along St. Mary's and O'Plaine Roads, then later subdivisions like Saddle Hill (1980s), Reigate Woods, and Lake Somerset (1990s) near Route 137. The K-8 Oak Grove School (District 68) sits inside the village on O'Plaine Road, high schoolers head to Libertyville High School, and commuters reach I-94 in minutes or Metra's MD-N line in Libertyville.
The initial zoning for one-, two-, and five-acre wooded lots means generous lot sizes and setbacks, allowing for significant horizontal expansion on custom homes along St. Mary's and O'Plaine Roads. Later subdivisions like Saddle Hill, Reigate Woods, and Lake Somerset near Route 137 will require careful consideration of their specific lot sizes and setback requirements for additions. Existing roof lines and foundations from the 1960s-80s custom homes and 1980s-90s subdivision builds will need seamless integration for additions. Given the village's deliberate buffer against dense development, exterior changes for additions will be reviewed to maintain the established aesthetic of single-family homes on spacious, wooded lots. For homes on private wells and septic, additions involving new bathrooms or kitchens must account for well capacity and septic system health and placement.
Home additions in Green Oaks require a thorough plan review by the village, covering structural integrity, zoning compliance for setbacks and lot coverage, and architectural plans. GS Construction & Remodeling manages the entire permit application process, including scheduling all necessary inspections as the foundation, framing, electrical, plumbing, and mechanical phases of your addition are completed.

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.
