Home additions in Harwood Heights, IL
Expanding a home in Harwood Heights frequently involves working with the sturdy brick ranches and bungalows built from the late 1940s through the 1970s. These homes, while well-constructed, often feature compact original footprints that leave little room for growing families or evolving lifestyle needs. A typical home addition here transforms these layouts by extending living areas, adding new bedrooms, or creating dedicated workspaces. The goal is often to maximize usable square footage without sacrificing the character of the original mid-century architecture, thoughtfully integrating new construction with existing structures. This often means carefully considering how new spaces flow from older ones, especially in homes with distinct living and dining areas.
What Harwood Heights homeowners ask for
Harwood Heights homeowners frequently request family room additions to create more spacious gathering areas, often extending off the back of existing living rooms or kitchens. Second-story additions are also common, particularly on single-story ranches, to efficiently add multiple bedrooms and bathrooms without consuming valuable yard space. We also see demand for mudroom and laundry room additions, as many older homes lack these dedicated functional spaces.
About Harwood Heights
Harwood Heights squeezes a lot of postwar suburbia into 0.83 square miles. Remodeling here works within tight footprints, so finished basements, reworked kitchens, and well-planned additions often beat moving.
Together with Norridge, it forms an enclave surrounded by the City of Chicago. Beyond a small pocket of 1930s Durocraft homes south of Foster Avenue, nearly all of the housing arrived between the late 1940s and the 1970s: brick ranches and bungalows on compact lots, plus 1960s high-rises like Parkway Towers. Most families are served by one-school Union Ridge District 86 and Ridgewood Community High School, though portions of the village fall in Pennoyer District 79, Norridge District 80, and Maine Township District 207; the CTA Blue Line at Harlem on the Kennedy serves commuters.
The compact lots prevalent from the late 1940s through the 1970s mean that additions often require careful consideration of setbacks, with second-story additions on ranches and bungalows being a common strategy to expand without exceeding lot coverage limits. Tying into existing brick ranches and bungalows necessitates matching rooflines and foundations to maintain architectural consistency and structural integrity. The presence of 1930s Durocraft homes south of Foster Avenue suggests a need to adapt to potentially different construction methods and materials for additions in that specific area. Given that the village reviews exterior changes, any addition must be designed to integrate seamlessly with the existing structure and neighborhood aesthetic. Confirming the service line inventory for lead is crucial for plumbing-heavy additions, necessitating coordination with the Village's water system requirements.
Home additions in Harwood Heights require comprehensive plan review for structural integrity, electrical, plumbing, and HVAC systems. The Village Building Department will schedule multiple inspections at various stages of construction, including foundation, framing, rough-ins, and final occupancy. GS Construction & Remodeling manages all permit applications and coordinates every required inspection to ensure compliance.
