Rarely available and ideally located, 123 Happ Road offers a premier redevelopment opportunity in the heart of Northfield. Set on an expansive 18,208 sq ft parcel, this deep lot presents the perfect canvas for a custom new construction home. The existing structure is a legal nonconforming two-flat in need of significant renovation, and most buyers will view this as a land-value opportunity. Zoned R-4 single family, the property allows for generous building potential within standard setbacks and zoning regulations. Located within walking distance to Clarkson Park, Mariano's, the public library and Northfield's Town Center, the neighborhood also offers convenient access to I-94, nearby forest preserves, and North Shore trail systems. Located in top-ranked Avoca District 37 and New Trier High School district 203, this property presents a rare chance for builders or homeowners with vision to create something exceptional in a highly desirable North Shore community. Please call the listing agent for complete details on zoning and allowable use. 119 Happ Road to the south is also listed as land and 2-4 unit. Do not walk the lot without a confirmed appointment.
