Home additions in Highland Park, IL
Expanding a home in Highland Park often means blending new construction seamlessly with established architectural styles, whether it's a 1920s Tudor or a mid-century ranch. Many homeowners are looking to create more expansive living areas, adding square footage to homes originally designed with more compartmentalized layouts. This can involve extending a rear facade for a larger kitchen and family room, or building up to add a primary suite above an existing garage. The challenge and beauty lie in respecting the original footprint and aesthetic, ensuring the addition looks and feels like an organic part of the home's history. We frequently work with properties that require careful consideration of their period-specific details and materials.
What Highland Park homeowners ask for
Highland Park homeowners frequently request two-story additions to expand living space without sacrificing yard area, especially on narrower lots. Another common request is for single-story rear additions to create open-concept kitchen and family rooms, improving flow and maximizing natural light. Many also seek to add dedicated home offices or first-floor primary suites, adapting their existing homes to evolving lifestyle needs.
About Highland Park
Highland Park has been building homes since its 1869 founding, and its streets show it. The city’s rich architectural tapestry reflects a journey from early Victorian and Queen Anne styles, particularly around the original downtown core, through the Arts and Crafts movement, and into the widespread influence of Prairie School design.
This deep history is evident with Frank Lloyd Wright’s 1901 Willits House standing prominently on Sheridan Road, a testament to the era’s innovative spirit. The National Register further lists local homes by esteemed architects like David Adler, Howard Van Doren Shaw, and Robert Seyfarth, contributing to a diverse and often historically significant housing stock.
Later in the 20th century, particularly through the mid-century, Highland Park saw the development of more modern and ranch-style homes, often with open floor plans and larger windows. The Fort Sheridan Historic District, for example, uniquely repurposed 1890s officers' quarters into one-of-a-kind residences, presenting a distinct set of considerations for remodeling, from preserving historical integrity to adapting layouts for contemporary living. Neighborhoods like Ravinia, which maintained its own village identity until 1899, and Braeside, each with their own UP-N Metra stations, often feature a mix of these architectural styles, with homes reflecting various construction periods and original designs. The walk-to-town lifestyle, anchored by Downtown’s Central Avenue shops and Metra stop, is a key draw, and many homes are designed to take advantage of this proximity. While some areas, particularly along the lakefront and in older sections, feature narrower lots and established landscaping, other subdivisions offer more generous footprints, allowing for potential additions and expanded outdoor living spaces.
For additions, the presence of Frank Lloyd Wright’s Willits House and other architect-designed homes means careful planning to tie into diverse roof lines and foundations, respecting the existing historical integrity. Mid-century modern and ranch-style homes often allow for more flexible additions due to their open floor plans and larger windows, while Fort Sheridan's repurposed officers' quarters demand unique considerations for adapting layouts. Narrower lots in older sections and along the lakefront require creative solutions for setbacks, contrasting with subdivisions offering more generous footprints for expanded outdoor living. Given the architectural significance of many homes, especially within the Fort Sheridan Historic District or properties designed by notable architects, homeowners should anticipate appearance review processes or specific guidelines for exterior changes.
Home additions in Highland Park require comprehensive plan review for structural integrity, electrical, plumbing, and HVAC systems, all of which trigger specific inspections. GS Construction & Remodeling meticulously prepares all necessary documentation and manages the full application and inspection scheduling process through the Civic Access Portal.

We have used GS for two bathroom projects-the first a small update; the second a complete remodel. We were thrilled with both. Everything was as promised; the timeline, price, and what it would look like. We were able to buy our own tile and fixtures and were not tied to any company's showroom. We got what we wanted and likely saved money doing so. GS also installed interior doors. The workmanship was great. The only downside is that now the bathrooms are the two nicest rooms in the house! I would heartily recommend GS construction!
